Abstract
Un atacante puede ser capaz de crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo con toda probabilidad las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada. Incluso la capacidad para controlar los argumentos pasados a un determinado método o constructor puede aportar a un usuario malintencionado y astuto el margen necesario para ejecutar un ataque con éxito.

Ejemplo 1: Un motivo común por el cual los programadores utilizan la tecnología de reflexión es el de implementar su propio distribuidor de comandos. El ejemplo siguiente muestra un distribuidor de comandos que no utiliza la reflexión:


var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var ctl:String = String(params["ctl"]);
var ao:Worker;
if (ctl == "Add) {
ao = new AddCommand();
} else if (ctl == "Modify") {
ao = new ModifyCommand();
} else {
throw new UnknownActionError();
}
ao.doAction(params);


Un programador podría refactorizar este código para utilizar la reflexión tal y como se muestra a continuación:


var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var ctl:String = String(params["ctl"]);
var ao:Worker;
var cmdClass:Class = getDefinitionByName(ctl + "Command") as Class;
ao = new cmdClass();
ao.doAction(params);


La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite que un usuario malintencionado cree instancias de cualquier objeto que implemente la interfaz Worker. Si el distribuidor de comandos sigue siendo responsable del control de acceso, entonces cada vez que los programadores creen una nueva clase que implemente la interfaz Worker, no deben olvidar modificar el código de control de acceso del distribuidor. Si no pueden modificar el código de control de acceso, algunas clases Worker no tendrán ningún control de acceso.

Una manera de solucionar este problema de control de acceso es hacer que el objeto Worker sea responsable de realizar la comprobación de control de acceso. A continuación se muestra un ejemplo del código refactorizado:


var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var ctl:String = String(params["ctl"]);
var ao:Worker;
var cmdClass:Class = getDefinitionByName(ctl + "Command") as Class;
ao = new cmdClass();
ao.checkAccessControl(params);
ao.doAction(params);


Aunque esto es una mejora, fomenta un método descentralizado de controlar el acceso, lo que aumenta las posibilidades de que los programadores cometan errores de control de acceso.

Abstract
Permitir que entradas no validadas determinen el método de devolución de llamada de un objeto Continuation podría permitir a los atacantes crear rutas de flujo de control inesperadas a través de la aplicación, lo que podría eludir los controles de seguridad.
Explanation
Si un atacante puede proporcionar valores que posteriormente la aplicación use para determinar qué clase instanciar o qué método invocar, el atacante podría crear rutas de flujo de control inesperadas a través de la aplicación. Esto podría permitir al atacante eludir las verificaciones de autenticación o control de acceso o quizá hacer que la aplicación se comporte de manera inesperada.

Ejemplo 1: El siguiente método de acción inicia una solicitud asincrónica a un servicio web externo y establece la propiedad continuationMethod, que determina el nombre del método al que se llamará al recibir una respuesta.

public Object startRequest() {
Continuation con = new Continuation(40);

Map<String,String> params = ApexPages.currentPage().getParameters();

if (params.containsKey('contMethod')) {
con.continuationMethod = params.get('contMethod');
} else {
con.continuationMethod = 'processResponse';
}

HttpRequest req = new HttpRequest();
req.setMethod('GET');
req.setEndpoint(LONG_RUNNING_SERVICE_URL);
this.requestLabel = con.addHttpRequest(req);
return con;
}

Esta implementación permite que la propiedad continuationMethod se establezca mediante parámetros de solicitud de tiempo de ejecución, lo que permite a los atacantes llamar a cualquier función que coincida con el nombre.

Ejemplo 1: Los programadores utilizan a menudo la reflexión para implementar distribuidores de comandos. En el siguiente ejemplo se muestra un distribuidor de comandos que no utiliza la reflexión:


...
Dim ctl As String
Dim ao As New Worker()
ctl = Request.Form("ctl")
If (String.Compare(ctl,"Add") = 0) Then
ao.DoAddCommand(Request)
Else If (String.Compare(ctl,"Modify") = 0) Then
ao.DoModifyCommand(Request)
Else
App.EventLog("No Action Found", 4)
End If
...


Un programador podría refactorizar este código para utilizar la reflexión tal y como se muestra a continuación:


...
Dim ctl As String
Dim ao As New Worker()
ctl = Request.Form("ctl")
CallByName(ao, ctl, vbMethod, Request)
...


La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite a un usuario malintencionado llamar a cualquier método implementado por el objeto Worker. Si el distribuidor de comandos se encarga del control de acceso, cada vez que los programadores creen un número método en la clase Worker, deben acordarse de modificar la lógica de control de acceso del distribuidor. Si esta lógica de control de acceso se queda obsoleta, algunos métodos Worker no tendrán ningún control de acceso.

Una manera de solucionar este problema de control de acceso es hacer que el objeto Worker sea responsable de realizar la comprobación de control de acceso. A continuación se muestra un ejemplo del código refactorizado:


...
Dim ctl As String
Dim ao As New Worker()
ctl = Request.Form("ctl")
If (ao.checkAccessControl(ctl,Request) = True) Then
CallByName(ao, "Do" & ctl & "Command", vbMethod, Request)
End If
...


Aunque esto es una mejora, fomenta un método descentralizado de controlar el acceso, lo que aumenta las posibilidades de que los programadores cometan errores de control de acceso.

Abstract
Un atacante puede ser capaz de crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo con toda probabilidad las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada.

Esta situación se convierte en una situación crítica si el atacante puede cargar archivos en una ubicación que aparezca en la ruta de la aplicación o la biblioteca. En cualquiera de estas situaciones, el atacante puede usar la reflexión para introducir un nuevo comportamiento presuntamente malicioso en la aplicación.
Ejemplo 1: Un motivo habitual por el que los programadores utilizan la API de reflexión consiste en implementar su propio distribuidor de comandos. En el siguiente ejemplo se muestra un distribuidor de comandos JNI que utiliza la reflexión para ejecutar un método de Java identificado por un valor leído desde una solicitud CGI. Esta implementación permite a un usuario malintencionado llamar a cualquier función definida en clazz.


char* ctl = getenv("ctl");
...
jmethodID mid = GetMethodID(clazz, ctl, sig);
status = CallIntMethod(env, clazz, mid, JAVA_ARGS);
...

Abstract
La interpretación de las instrucciones controladas por el usuario en tiempo de ejecución puede permitir a los usuarios malintencionados ejecutar código malintencionado.
Explanation
Si un atacante puede proporcionar valores que la aplicación luego utiliza para determinar qué método invocar o qué valor de campo recuperar, existe la posibilidad de que el atacante cree rutas de flujo de control a través de la aplicación que no fueron previstas por los desarrolladores de la aplicación. Este vector de ataque podría permitir al atacante eludir las verificaciones de autenticación o control de acceso o, de lo contrario, hacer que la aplicación se comporte de manera inesperada.

Ejemplo 1: en este ejemplo, la aplicación recupera el nombre de una función a la que se va a llamar desde un argumento de la línea de comandos.


...
func beforeExampleCallback(scope *Scope){
input := os.Args[1]
if input{
scope.CallMethod(input)
}
}
...
Ejemplo 2: Similar al ejemplo anterior, la aplicación utiliza el paquete reflect para recuperar el nombre de una función a la que se va a llamar desde un argumento de la línea de comandos.

...
input := os.Args[1]
var worker WokerType
reflect.ValueOf(&worker).MethodByName(input).Call([]reflect.Value{})
...

Abstract
Un atacante puede ser capaz de crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo con toda probabilidad las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada. Incluso la capacidad para controlar los argumentos pasados a un determinado método o constructor puede aportar a un usuario malintencionado y astuto el margen necesario para ejecutar un ataque con éxito.

Esta situación pasa a ser crítica si el atacante puede cargar archivos en una ubicación que aparezca en la ruta de clase de la aplicación o añadir entradas a la ruta de clase de la aplicación. En cualquiera de estas situaciones, el atacante puede usar la reflexión para introducir un nuevo comportamiento presuntamente malicioso en la aplicación.
Ejemplo 1: Un motivo habitual por el que los programadores utilizan la API de reflexión consiste en implementar su propio distribuidor de comandos. El ejemplo siguiente muestra un distribuidor de comandos que no utiliza la reflexión:


String ctl = request.getParameter("ctl");
Worker ao = null;
if (ctl.equals("Add")) {
ao = new AddCommand();
} else if (ctl.equals("Modify")) {
ao = new ModifyCommand();
} else {
throw new UnknownActionError();
}
ao.doAction(request);


Un programador podría refactorizar este código para utilizar la reflexión tal y como se muestra a continuación:


String ctl = request.getParameter("ctl");
Class cmdClass = Class.forName(ctl + "Command");
Worker ao = (Worker) cmdClass.newInstance();
ao.doAction(request);


La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite que un usuario malintencionado cree instancias de cualquier objeto que implemente la interfaz Worker. Si el distribuidor de comandos sigue siendo responsable del control de acceso, entonces cada vez que los programadores creen una nueva clase que implemente la interfaz Worker, no deben olvidar modificar el código de control de acceso del distribuidor. Si no pueden modificar el código de control de acceso, algunas clases Worker no tendrán ningún control de acceso.

Una manera de solucionar este problema de control de acceso es hacer que el objeto Worker sea responsable de realizar la comprobación de control de acceso. A continuación se muestra un ejemplo del código refactorizado:


String ctl = request.getParameter("ctl");
Class cmdClass = Class.forName(ctl + "Command");
Worker ao = (Worker) cmdClass.newInstance();
ao.checkAccessControl(request);
ao.doAction(request);


Aunque esto es una mejora, fomenta un método descentralizado de controlar el acceso, lo que aumenta las posibilidades de que los programadores cometan errores de control de acceso.

Este código también pone de manifiesto otro problema de seguridad relacionado con el uso de la reflexión para crear un distribuidor de comandos. Un atacante puede llamar al constructor predeterminado en relación con cualquier tipo de objeto. De hecho, el usuario malintencionado no está limitado solo a los objetos que implementan la interfaz de Worker; se puede llamar al constructor predeterminado de cualquier objeto del sistema. Si el objeto no implementa la interfaz de Worker, se generará una ClassCastException antes de la asignación a ao. Sin embargo, si el constructor realiza operaciones que trabajan a favor del usuario malintencionado, el daño ya estará hecho. Aunque este escenario es relativamente benigno en aplicaciones sencillas, en las aplicaciones de mayor tamaño en las que la complejidad crece exponencialmente, es razonable creer que un usuario malintencionado podría encontrar un constructor para aprovecharlo como parte de un ataque.

Las comprobaciones de acceso también pueden verse comprometidas más adelante en la cadena de ejecución de código si se llama a determinadas API de Java que realizan tareas mediante la comprobación del cargador de clases del autor de la llamada inmediato, en objetos poco confiables devueltos por las llamadas de reflexión. Estas API de Java omiten la comprobación de SecurityManager que garantiza que todos los autores de llamadas de la cadena de ejecución dispongan de los permisos de seguridad necesarios. Se debe tener cuidado para garantizar que se llame a estas API en los objetos que no son de confianza devueltos por la reflexión, ya que pueden omitir las comprobaciones de acceso de seguridad y dejar al sistema vulnerable frente a ataques remotos. Para obtener más información sobre estas API de Java, consulte la directriz 9 de The Secure Coding Guidelines for the Java Programming Language (Directrices de creación segura de código para el lenguaje de programación Java).

Abstract
Los atacantes pueden controlar un argumento al método performSelector, lo que podría permitirles crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo potencialmente las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada.

Ejemplo 1: Es un motivo común por el cual los programadores utilizan la API del selector para implementar su propio distribuidor de comandos. En el ejemplo siguiente se muestra un distribuidor de comandos de Objective-C que utiliza la reflexión para ejecutar un método arbitrario identificado por un valor de lectura a partir de una solicitud de esquema de URL personalizado. Esta implementación permite que un atacante llame a cualquier función que coincida con la firma del método definida en la clase UIApplicationDelegate.

Abstract
Un atacante puede ser capaz de crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo con toda probabilidad las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada. Incluso la capacidad para controlar los argumentos pasados a un determinado método o constructor puede aportar a un usuario malintencionado y astuto el margen necesario para ejecutar un ataque con éxito.

Esta situación pasa a ser crítica si el atacante puede cargar archivos en una ubicación que aparezca en la ruta de clase de la aplicación o añadir entradas a la ruta de clase de la aplicación. En cualquiera de estas situaciones, el atacante puede usar la reflexión para introducir un nuevo comportamiento presuntamente malicioso en la aplicación.
Ejemplo 1: Un motivo habitual por el que los programadores utilizan la API de reflexión consiste en implementar su propio distribuidor de comandos. El ejemplo siguiente muestra un distribuidor de comandos que no utiliza la reflexión:


$ctl = $_GET["ctl"];
$ao = null;
if (ctl->equals("Add")) {
$ao = new AddCommand();
} else if ($ctl.equals("Modify")) {
$ao = new ModifyCommand();
} else {
throw new UnknownActionError();
}
$ao->doAction(request);


Un programador podría refactorizar este código para utilizar la reflexión tal y como se muestra a continuación:


$ctl = $_GET["ctl"];
$args = $_GET["args"];
$cmdClass = new ReflectionClass(ctl . "Command");
$ao = $cmdClass->newInstance($args);
$ao->doAction(request);


La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite que un usuario malintencionado cree instancias de cualquier objeto que implemente la interfaz Worker. Si el distribuidor de comandos sigue siendo responsable del control de acceso, entonces cada vez que los programadores creen una nueva clase que implemente la interfaz Worker, no deben olvidar modificar el código de control de acceso del distribuidor. Si no pueden modificar el código de control de acceso, algunas clases Worker no tendrán ningún control de acceso.

Una manera de solucionar este problema de control de acceso es hacer que el objeto Worker sea responsable de realizar la comprobación de control de acceso. A continuación se muestra un ejemplo del código refactorizado:


$ctl = $_GET["ctl"];
$args = $_GET["args"];
$cmdClass = new ReflectionClass(ctl . "Command");
$ao = $cmdClass->newInstance($args);
$ao->checkAccessControl(request);
ao->doAction(request);


Aunque esto es una mejora, fomenta un método descentralizado de controlar el acceso, lo que aumenta las posibilidades de que los programadores cometan errores de control de acceso.

Este código también pone de manifiesto otro problema de seguridad relacionado con el uso de la reflexión para crear un distribuidor de comandos. Un atacante puede llamar al constructor predeterminado en relación con cualquier tipo de objeto. De hecho, el usuario malintencionado no está limitado solo a los objetos que implementan la interfaz de Worker; se puede llamar al constructor predeterminado de cualquier objeto del sistema. Si el objeto no implementa la interfaz de Worker, se generará una ClassCastException antes de la asignación a $ao. Sin embargo, si el constructor realiza operaciones que trabajan a favor del usuario malintencionado, el daño ya estará hecho. Aunque este escenario es relativamente benigno en aplicaciones sencillas, en las aplicaciones de mayor tamaño en las que la complejidad crece exponencialmente, es razonable creer que un usuario malintencionado podría encontrar un constructor para aprovecharlo como parte de un ataque.

Abstract
Un atacante puede ser capaz de crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo con toda probabilidad las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien hacer que la aplicación se comporte de forma inesperada. Incluso la capacidad para controlar los argumentos pasados a un determinado método o constructor puede aportar a un usuario malintencionado y astuto el margen necesario para ejecutar un ataque con éxito.

Esta situación pasa a ser crítica si el atacante puede cargar archivos en una ubicación que aparezca en la ruta de carga de la aplicación o añadir entradas a la ruta de carga de la aplicación. En cualquiera de estas situaciones, el atacante puede usar la reflexión para introducir un nuevo comportamiento presuntamente malicioso en la aplicación.
Ejemplo 1: Un motivo común por el cual los programadores utilizan la reflexión es el de implementar su propio distribuidor de comandos. El ejemplo siguiente muestra un distribuidor de comandos que no utiliza la reflexión:


ctl = req['ctl']
if ctl=='add'
addCommand(req)
elsif ctl=='modify'
modifyCommand(req)
else
raise UnknownCommandError.new
end


Un programador podría refactorizar este código para utilizar la reflexión tal y como se muestra a continuación:


ctl = req['ctl']
ctl << "Command"
send(ctl)


La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite a un usuario malintencionado ejecutar cualquier método que termine con la palabra "Command". Si el distribuidor de comandos sigue siendo responsable del control de acceso, siempre que los programadores creen un nuevo método que termine con "Command", deberán acordarse de modificar el código de control de acceso del distribuidor. Incluso entonces, el procedimiento habitual cuando hay varios métodos con nombres similares puede ser crearlos dinámicamente mediante define_method() o llamarlos mediante el reemplazo de missing_method(). Auditar y realizar un seguimiento de estos métodos y de cómo se utiliza el código de control de acceso con ellos resulta muy difícil, y si consideramos que también depende de qué código de biblioteca se cargue, realizar esta tarea correctamente puede convertirse en una misión imposible.

En cualquiera de estas situaciones, el atacante puede usar la reflexión para introducir un nuevo comportamiento presuntamente malicioso en la aplicación.
Ejemplo 1: Un motivo habitual por el que los programadores utilizan la API de reflexión consiste en implementar su propio distribuidor de comandos. El ejemplo siguiente muestra un distribuidor de comandos que utiliza la reflexión:


def exec(ctl: String) = Action { request =>
val cmdClass = Platform.getClassForName(ctl + "Command")
Worker ao = (Worker) cmdClass.newInstance()
ao.doAction(request)
...
}


La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite que un usuario malintencionado cree instancias de cualquier objeto que implemente la interfaz Worker. Si el distribuidor de comandos sigue siendo responsable del control de acceso, entonces cada vez que los programadores creen una nueva clase que implemente la interfaz Worker, no deben olvidar modificar el código de control de acceso del distribuidor. Si no pueden modificar el código de control de acceso, algunas clases Worker no tendrán ningún control de acceso.

Una manera de solucionar este problema de control de acceso es hacer que el objeto Worker sea responsable de realizar la comprobación de control de acceso. A continuación se muestra un ejemplo del código refactorizado:


def exec(ctl: String) = Action { request =>
val cmdClass = Platform.getClassForName(ctl + "Command")
Worker ao = (Worker) cmdClass.newInstance()
ao.checkAccessControl(request);
ao.doAction(request)
...
}


Aunque esto es una mejora, fomenta un método descentralizado de controlar el acceso, lo que aumenta las posibilidades de que los programadores cometan errores de control de acceso.

Este código también pone de manifiesto otro problema de seguridad relacionado con el uso de la reflexión para crear un distribuidor de comandos. Un atacante puede llamar al constructor predeterminado en relación con cualquier tipo de objeto. De hecho, el usuario malintencionado no está limitado solo a los objetos que implementan la interfaz de Worker; se puede llamar al constructor predeterminado de cualquier objeto del sistema. Si el objeto no implementa la interfaz de Worker, se generará una ClassCastException antes de la asignación a ao. Sin embargo, si el constructor realiza operaciones que trabajan a favor del usuario malintencionado, el daño ya estará hecho. Aunque este escenario es relativamente benigno en aplicaciones sencillas, en las aplicaciones de mayor tamaño en las que la complejidad crece exponencialmente, es razonable creer que un usuario malintencionado podría encontrar un constructor para aprovecharlo como parte de un ataque.

Las comprobaciones de acceso también pueden verse comprometidas más adelante en la cadena de ejecución de código si se llama a determinadas API de Java que realizan tareas mediante la comprobación del cargador de clases del autor de la llamada inmediato, en objetos poco confiables devueltos por las llamadas de reflexión. Estas API de Java omiten la comprobación de SecurityManager que garantiza que todos los autores de llamadas de la cadena de ejecución dispongan de los permisos de seguridad necesarios. Se debe tener cuidado para garantizar que se llame a estas API en los objetos que no son de confianza devueltos por la reflexión, ya que pueden omitir las comprobaciones de acceso de seguridad y dejar al sistema vulnerable frente a ataques remotos. Para obtener más información sobre estas API de Java, consulte la directriz 9 de The Secure Coding Guidelines for the Java Programming Language (Directrices de creación segura de código para el lenguaje de programación Java).

Abstract
Los atacantes pueden controlar un argumento al método performSelector, lo que podría permitirles crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo potencialmente las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada.

Ejemplo 1: Es un motivo común por el cual los programadores utilizan la API del selector para implementar su propio distribuidor de comandos. En el ejemplo siguiente se muestra un distribuidor de comandos de Swift que utiliza la reflexión para ejecutar un método arbitrario identificado por un valor de lectura a partir de una solicitud de esquema de URL personalizado. Esta implementación permite que un atacante llame a cualquier función que coincida con la firma del método definida en la clase UIApplicationDelegate.


func application(app: UIApplication, openURL url: NSURL, options: [String : AnyObject]) -> Bool {
...
let query = url.query
let pathExt = url.pathExtension
let selector = NSSelectorFromString(pathExt!)
performSelector(selector, withObject:query)
...
}

Abstract
Un atacante puede ser capaz de crear rutas de flujo de control inesperadas a través de la aplicación, omitiendo con toda probabilidad las comprobaciones de seguridad.
Explanation
Si un usuario malintencionado puede suministrar los valores que la aplicación más tarde utiliza para determinar con qué clase se puede crear una instancia o qué método se puede invocar, existe la posibilidad de que el usuario malintencionado cree rutas de flujo de control a través de la aplicación que no han diseñado los desarrolladores de aplicaciones. Este tipo de ataque puede permitir que el usuario malintencionado eluda la autenticación o las comprobaciones del control de acceso, o bien que de cualquier otra manera, provoque que la aplicación se comporte de forma inesperada. Incluso la capacidad para controlar los argumentos pasados a un determinado método o constructor puede aportar a un usuario malintencionado y astuto el margen necesario para ejecutar un ataque con éxito.

Ejemplo 1: Un motivo común por el cual los programadores utilizan CallByName es el de implementar su propio distribuidor de comandos. En el ejemplo siguiente se muestra un distribuidor de comandos que no utiliza la función CallByName:


...
Dim ctl As String
Dim ao As new Worker
ctl = Request.Form("ctl")
If String.Compare(ctl,"Add") = 0 Then
ao.DoAddCommand Request
Else If String.Compare(ctl,"Modify") = 0 Then
ao.DoModifyCommand Request
Else
App.EventLog "No Action Found", 4
End If
...



Un programador podría refactorizar este código para utilizar la reflexión tal y como se muestra a continuación:


...
Dim ctl As String
Dim ao As Worker
ctl = Request.Form("ctl")
CallByName ao, ctl, vbMethod, Request
...




La refactorización al principio parece que ofrece una serie de ventajas. Hay menos líneas de código, los bloques if/else se han eliminado por completo y ahora es posible agregar nuevos tipos de comando sin modificar el distribuidor de comandos.

Sin embargo, la refactorización permite a un usuario malintencionado llamar a cualquier método implementado por el objeto Worker. Si el distribuidor de comandos sigue siendo responsable del control de acceso, siempre que los programadores creen un nuevo método dentro de la clase Worker, deberán acordarse de modificar el código de control de acceso del distribuidor. Si no pueden modificar el código de control de acceso, algunos métodos de Worker no tendrán ningún control de acceso.

Una manera de solucionar este problema de control de acceso es hacer que el objeto Worker sea responsable de realizar la comprobación de control de acceso. A continuación se muestra un ejemplo del código refactorizado:


...
Dim ctl As String
Dim ao As Worker
ctl = Request.Form("ctl")
If ao.checkAccessControl(ctl,Request) = True Then
CallByName ao, "Do" & ctl & "Command", vbMethod, Request
End If
...



Aunque esto es una mejora, fomenta un método descentralizado de controlar el acceso, lo que aumenta las posibilidades de que los programadores cometan errores de control de acceso.

Abstract
Los valores de hash criptográficos débiles no pueden garantizar la integridad de los datos y no deberían utilizarse en contextos críticos de seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de valores de hash criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, puesto que avances recientes en el criptoanálisis han descubierto puntos débiles en ambos algoritmos, ya no deberían utilizarse en contextos críticos de seguridad.

Hay disponibles diversas técnicas muy eficaces para cancelar los valores de hash MD5 y RIPEMD, por lo que no se debería confiar la seguridad a esos algoritmos. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los usuarios malintencionados han encontrado el talón de Aquiles del algoritmo, y las técnicas para romperlo darán lugar con toda probabilidad al descubrimiento de ataques aún más rápidos.

Abstract
Los hashes criptográficos débiles no pueden garantizar la integridad de los datos y no deben usarse en contextos esenciales para la seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de hashes criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. La investigación de criptoanálisis ha revelado debilidades fundamentales en estos algoritmos y no se recomienda su uso en contextos críticos de seguridad.

No dependa de los algoritmos de hash MD y RIPEMD para la seguridad. Hay disponibles de forma generalizada técnicas eficaces para cancelar hash MD y RIPEMD. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son difíciles de implementar. Sin embargo, los atacantes descubrieron que las debilidades en el algoritmo y las técnicas para cancelarlo pueden conducir al descubrimiento de ataques aún más rápidos.

Abstract
Los valores de hash criptográficos débiles no pueden garantizar la integridad de los datos y no deberían utilizarse en contextos críticos de seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de valores de hash criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, puesto que avances recientes en el criptoanálisis han descubierto puntos débiles en ambos algoritmos, ya no deberían utilizarse en contextos críticos de seguridad.

Hay disponibles diversas técnicas muy eficaces para cancelar los valores de hash MD5 y RIPEMD, por lo que no se debería confiar la seguridad a esos algoritmos. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los usuarios malintencionados han encontrado el talón de Aquiles del algoritmo, y las técnicas para romperlo darán lugar con toda probabilidad al descubrimiento de ataques aún más rápidos.

Abstract
No utilice hashes criptográficos débiles en contextos críticos de seguridad debido a que no está garantizada la integridad de los datos.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de hashes criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. La investigación de criptoanálisis ha revelado debilidades fundamentales en estos algoritmos, por lo que no se recomienda su uso en contextos críticos de seguridad.

No dependa de los algoritmos de hash MD y RIPEMD para la seguridad. Hay disponibles de forma generalizada técnicas eficaces para cancelar hash MD y RIPEMD. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son difíciles de implementar. Sin embargo, los atacantes descubrieron que las debilidades en el algoritmo y las técnicas para cancelarlo pueden conducir al descubrimiento de ataques aún más rápidos.

Abstract
Los valores de hash criptográficos débiles no pueden garantizar la integridad de los datos y no deberían utilizarse en contextos críticos de seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de valores de hash criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, puesto que avances recientes en el criptoanálisis han descubierto puntos débiles en ambos algoritmos, ya no deberían utilizarse en contextos críticos de seguridad.

Hay disponibles diversas técnicas muy eficaces para cancelar los valores de hash MD5 y RIPEMD, por lo que no se debería confiar la seguridad a esos algoritmos. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los usuarios malintencionados han encontrado el talón de Aquiles del algoritmo, y las técnicas para romperlo darán lugar con toda probabilidad al descubrimiento de ataques aún más rápidos.

Abstract
La llamada identificada utiliza potencialmente los valores de hash cifrados débiles. Los valores de hash criptográficos débiles no pueden garantizar la integridad de los datos y no deberían utilizarse en contextos críticos de seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de valores de hash criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, puesto que avances recientes en el criptoanálisis han descubierto puntos débiles en ambos algoritmos, ya no deberían utilizarse en contextos críticos de seguridad.

Ejemplo 1: El código siguiente utiliza un algoritmo de hash débil (MD5):


NSData *imageData = [NSData dataWithContentsOfFile:file];
CC_MD5(imageData, [imageData length], result);


Hay disponibles diversas técnicas muy eficaces para cancelar los valores de hash MD5 y RIPEMD, por lo que no se debería confiar la seguridad a esos algoritmos. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los usuarios malintencionados han encontrado el talón de Aquiles del algoritmo, y las técnicas para romperlo darán lugar con toda probabilidad al descubrimiento de ataques aún más rápidos.

Abstract
Los valores de hash criptográficos débiles no pueden garantizar la integridad de los datos y no deberían utilizarse en contextos críticos de seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de valores de hash criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, puesto que avances recientes en el criptoanálisis han descubierto puntos débiles en ambos algoritmos, ya no deberían utilizarse en contextos críticos de seguridad.

Hay disponibles diversas técnicas muy eficaces para cancelar los valores de hash MD5 y RIPEMD, por lo que no se debería confiar la seguridad a esos algoritmos. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los usuarios malintencionados han encontrado el talón de Aquiles del algoritmo, y las técnicas para romperlo darán lugar con toda probabilidad al descubrimiento de ataques aún más rápidos.

Abstract
La llamada identificada utiliza los valores de hash cifrados débiles. Los valores de hash criptográficos débiles no pueden garantizar la integridad de los datos y no deberían utilizarse en contextos críticos de seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de valores de hash criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, puesto que avances recientes en el criptoanálisis han descubierto puntos débiles en ambos algoritmos, ya no deberían utilizarse en contextos críticos de seguridad.

Ejemplo 1: el código siguiente utiliza un algoritmo de hash débil (MD5):


let encodedText = text.cStringUsingEncoding(NSUTF8StringEncoding)
let textLength = CC_LONG(text.lengthOfBytesUsingEncoding(NSUTF8StringEncoding))
let digestLength = Int(CC_MD5_DIGEST_LENGTH)
let result = UnsafeMutablePointer<CUnsignedChar>.alloc(digestLength)

CC_MD5(encodedText, textLength, result)


Hay disponibles diversas técnicas muy eficaces para cancelar los valores de hash MD5 y RIPEMD, por lo que no se debería confiar la seguridad a esos algoritmos. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los usuarios malintencionados han encontrado el talón de Aquiles del algoritmo, y las técnicas para romperlo darán lugar con toda probabilidad al descubrimiento de ataques aún más rápidos.

Abstract
Los hashes criptográficos débiles no pueden garantizar la integridad de los datos y no deben usarse en contextos esenciales para la seguridad.
Explanation
MD2, MD4, MD5, RIPEMD-160 y SHA-1 son los algoritmos de hashes criptográficos conocidos que suelen utilizarse para comprobar la integridad de los mensajes y otros datos. Sin embargo, como la investigación reciente de criptoanálisis ha revelado debilidades fundamentales en estos algoritmos, ya no deberían usarse en contextos esenciales para la seguridad.

Las técnicas efectivas para romper los hashes MD y RIPEMD están ampliamente disponibles, por lo que no se debe confiar en esos algoritmos para la seguridad. En el caso de SHA-1, las técnicas actuales todavía requieren una cantidad significativa de capacidad computacional y son más difíciles de implementar. Sin embargo, los atacantes han encontrado las debilidades del algoritmo y las técnicas para cancelarlo pueden llevar al descubrimiento de ataques aún más rápidos.

Abstract
La sal vacía puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es una buena idea utilizar una sal vacía. El uso de sal vacía no solo facilita enormemente que puedan adivinarse los valores de hash, sino que además dificulta enormemente la solución del problema. Una vez que el código está en producción, no es fácil modificar la sal. Si los usuarios malintencionados descubren que los valores con hash tienen sal vacía, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: El código siguiente utiliza una sal vacía:

...
private static final String salt = "";
...
PBEKeySpec pbeSpec=new PBEKeySpec(password);
SecretKeyFactory keyFact=SecretKeyFactory.getInstance(CIPHER_ALG);
PBEParameterSpec defParams=new PBEParameterSpec(salt,100000);
Cipher cipher=Cipher.getInstance(CIPHER_ALG);
cipher.init(cipherMode,keyFact.generateSecret(pbeSpec),defParams);
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal (vacía). Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

desc.semantic.java.weak_cryptographic_hash_empty_pbe_salt
Abstract
La sal vacía puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es una buena idea utilizar una sal vacía. El uso de sal vacía no solo facilita enormemente que puedan adivinarse los valores de hash, sino que además dificulta enormemente la solución del problema. Una vez que el código está en producción, no es fácil modificar la sal. Si los usuarios malintencionados descubren que los valores con hash tienen sal vacía, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: El código siguiente utiliza una sal vacía:

...
const salt = "";
crypto.pbkdf2(
password,
salt,
iterations,
keyLength,
"sha256",
function (err, derivedKey) { ... }
);


Este código podría ejecutarse correctamente, pero cualquiera que tenga acceso a él podría descubrir que utiliza una sal vacía. Una vez lanzado el programa, no hay forma de cambiar la sal vacía, a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer el sistema.

Abstract
La sal vacía puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es una buena idea utilizar una sal vacía. El uso de sal vacía no solo facilita enormemente que puedan adivinarse los valores de hash, sino que además dificulta enormemente la solución del problema. Una vez que el código está en producción, no es fácil modificar sal. Si los usuarios malintencionados descubren que los valores con hash tienen sal vacía, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.

Ejemplo 1: el código siguiente utiliza sal vacía:

from hashlib import pbkdf2_hmac
...
dk = pbkdf2_hmac('sha256', password, '', 100000)
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal (vacía). Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

desc.structural.swift.weak_cryptographic_hash_empty_pbe_salt
Abstract
Una sal codificada puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar sal de forma rígida no solo permite que todos los desarrolladores de proyectos vean sal, sino que además dificulta muchísimo la solución del problema. Una vez que el código está en producción, no es fácil modificar sal. Si los usuarios malintencionados conocen el valor de sal, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: el código siguiente utiliza sal con codificación rígida:

...
PKCS5_PBKDF2_HMAC(pass, strlen(pass), "2!@$(5#@532@%#$253l5#@$", 2, ITERATION, EVP_sha512(), outputBytes, digest);
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal. Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal "2!@$(5#@532@%#$253l5#@$". Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

Abstract
Una sal codificada puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar una sal la pone a disposición de cualquier persona con acceso a la fuente y pone en peligro la solidez criptográfica de la función. Si los usuarios malintencionados conocen el valor de sal, pueden calcular "tablas arcoíris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: El código siguiente utiliza sal con codificación rígida:

...
const salt = "some constant value";
crypto.pbkdf2(
password,
salt,
iterations,
keyLength,
"sha256",
function (err, derivedKey) { ... }
);


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal. Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer el sistema.

Abstract
Una sal codificada puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar sal de forma rígida no solo permite que todos los desarrolladores de proyectos vean sal, sino que además dificulta muchísimo la solución del problema. Una vez que el código está en producción, no es fácil modificar sal. Si los usuarios malintencionados conocen el valor de sal, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: el código siguiente utiliza sal con codificación rígida:

...
CCKeyDerivationPBKDF(kCCPBKDF2,
password,
passwordLen,
"2!@$(5#@532@%#$253l5#@$",
2,
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal. Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal "2!@$(5#@532@%#$253l5#@$". Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

desc.structural.python.weak_cryptographic_hash_hardcoded_pbe_salt
Abstract
Una sal codificada puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar sal de forma rígida no solo permite que todos los desarrolladores de proyectos vean sal, sino que además dificulta muchísimo la solución del problema. Una vez que el código está en producción, no es fácil modificar sal. Si los usuarios malintencionados conocen el valor de sal, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: el código siguiente utiliza sal con codificación rígida:

...
dk = OpenSSL::PKCS5.pbkdf2_hmac(password, '2!@$(5#@532@%#$253l5#@$', 100000, 256, digest)
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal. Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal "2!@$(5#@532@%#$253l5#@$". Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar sal de forma rígida no solo permite que todos los desarrolladores de proyectos vean sal, sino que además dificulta muchísimo la solución del problema. Una vez que el código está en producción, no podrá cambiar sal con facilidad.

desc.structural.golang.weak_cryptographic_hash_hardcoded_salt
Abstract
Una sal codificada puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar sal de forma rígida no solo permite que todos los desarrolladores de proyectos vean sal, sino que además dificulta muchísimo la solución del problema. Una vez que el código está en producción, no es fácil modificar sal. Si los usuarios malintencionados conocen el valor de sal, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: el código siguiente utiliza sal con codificación rígida:

...
Encryptor instance = ESAPI.encryptor();
String hash1 = instance.hash(input, "2!@$(5#@532@%#$253l5#@$");
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal. Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal "2!@$(5#@532@%#$253l5#@$". Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Y lo que es peor, si los atacantes tienen acceso al código de bytes para la aplicación pueden usar el comando javap -c para acceder al código desensamblado, que contiene los valores de la sal usada.

desc.structural.python.weak_cryptographic_hash_hardcoded_salt
Abstract
Una sal codificada puede poner en riesgo la seguridad del sistema de una forma que no es fácil de resolver.
Explanation
Nunca es buena idea codificar sal de forma rígida. Codificar sal de forma rígida no solo permite que todos los desarrolladores de proyectos vean sal, sino que además dificulta muchísimo la solución del problema. Una vez que el código está en producción, no es fácil modificar sal. Si los usuarios malintencionados conocen el valor de sal, pueden calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.
Ejemplo 1: el siguiente código utiliza sal codificada para el hash de contraseña:

require 'openssl'
...
password = get_password()
salt = '2!@$(5#@532@%#$253l5#@$'
hash = OpenSSL::Digest::SHA256.digest(salt + password)
...


Este código se ejecutará correctamente, pero todo aquel que tenga acceso a él también tendrá acceso a sal. Una vez que se haya distribuido el programa, no hay otro modo de cambiar la sal "2!@$(5#@532@%#$253l5#@$". Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema.

Abstract
El recuento de iteraciones que usa una función de derivación de clave basada en contraseña es demasiado bajo.
Explanation
Una función de derivación de claves se utiliza para derivar una clave a partir de una clave base y otros parámetros. En una función de derivación de claves basada en contraseña, la clave base es una contraseña y los otros parámetros son un valor de sal y un número de iteraciones. El número de iteraciones ha servido tradicionalmente para aumentar el coste de generar claves a partir de una contraseña. Si el número de iteraciones es demasiado bajo, la viabilidad de un ataque aumenta a medida que un atacante puede calcular "tablas arcoíris" para la aplicación y revertir más fácilmente los valores de contraseña con hash.

Ejemplo 1: el código siguiente utiliza un recuento de iteraciones de 50:


...
Rfc2898DeriveBytes rdb8 = new Rfc2898DeriveBytes(password, salt,50);
...


Las aplicaciones que usan un recuento de iteraciones bajo para el cifrado basado en contraseñas se exponen a ataques por diccionario triviales, exactamente el tipo de ataques contra los que se diseñaron los esquemas de cifrado basado en contraseñas.

Abstract
El recuento de iteraciones que usa una función de derivación de clave basada en contraseña es demasiado bajo.
Explanation
Una función de derivación de claves se utiliza para derivar una clave a partir de una clave base y otros parámetros. En una función de derivación de claves basada en contraseña, la clave base es una contraseña y los otros parámetros son un valor de sal y un número de iteraciones. El número de iteraciones ha servido tradicionalmente para aumentar el coste de generar claves a partir de una contraseña. Si el recuento de iteraciones es demasiado bajo, la viabilidad de un ataque aumenta a medida que un atacante puede calcular "tablas de arcoíris" para la aplicación y determinar más fácilmente los valores de contraseña con hash.

Ejemplo 1: el código siguiente utiliza un recuento de iteraciones de 50:


...
final int iterationCount=50;
PBEParameterSpec pbeps=new PBEParameterSpec(salt,iterationCount);
...


Las aplicaciones que usan un recuento de iteraciones bajo para el cifrado basado en contraseña son vulnerables a los ataques por diccionario, que son precisamente los ataques ante los cuales deberían proteger los esquemas de cifrado basados en contraseña.

...
const iterations = 50;
crypto.pbkdf2(
password,
salt,
iterations,
keyLength,
"sha256",
function (err, derivedKey) { ... }
);


Las aplicaciones que utilizan un número bajo de iteraciones para el cifrado basado en contraseñas están expuestas a ataques triviales basados en diccionarios, exactamente el tipo de ataque contra el cual se diseñaron los esquemas de cifrado basados en contraseñas.

Abstract
El recuento de iteraciones que usa una función de derivación de clave basada en contraseña es demasiado bajo.
Explanation
Una función de derivación de claves se utiliza para derivar una clave a partir de una clave base y otros parámetros. En una función de derivación de claves basada en contraseña, la clave base es una contraseña y los otros parámetros son un valor de sal y un número de iteraciones. El número de iteraciones ha servido tradicionalmente para aumentar el coste de generar claves a partir de una contraseña. Si el número de iteraciones es demasiado bajo, la viabilidad de un ataque aumenta a medida que un atacante puede calcular "tablas arcoíris" para la aplicación y revertir más fácilmente los valores de contraseña con hash.

Ejemplo 1: El código siguiente utiliza un recuento de iteraciones de 50:


...
$hash = hash_pbkdf2('sha256', $password, $salt, 50);
...


Las aplicaciones que usan un recuento de iteraciones bajo para el cifrado basado en contraseñas se exponen a ataques por diccionario triviales, exactamente el tipo de ataques contra los que se diseñaron los esquemas de cifrado basado en contraseñas.

Explanation
Una función de derivación de claves se utiliza para derivar una clave a partir de una clave base y otros parámetros. En una función de derivación de claves basada en contraseña, la clave base es una contraseña y los otros parámetros son un valor de sal y un número de iteraciones. El número de iteraciones ha servido tradicionalmente para aumentar el coste de generar claves a partir de una contraseña. Si el número de iteraciones es demasiado bajo, la viabilidad de un ataque aumenta a medida que un atacante puede calcular "tablas arcoíris" para la aplicación y revertir más fácilmente los valores de contraseña con hash.

Ejemplo 1: el código siguiente utiliza un recuento de iteraciones de 50:


...
from hashlib import pbkdf2_hmac
dk = pbkdf2_hmac('sha256', password, salt, 50)
...


Las aplicaciones que utilizan un número bajo de iteraciones para el cifrado basado en contraseñas están expuestas a ataques triviales basados en diccionarios, que es exactamente el tipo de ataque contra el que se diseñaron los esquemas de cifrado basados en contraseñas.

Ejemplo 2: El siguiente código establece el parámetro de costo en 11:

bcrypt_hash = bcrypt(b64pwd, 11)

Al utilizar la API bcrypt en Pycryptodome, es crucial tener en cuenta que el parámetro de costo juega un papel importante en la determinación de la complejidad computacional del proceso de hash subyacente. Se recomienda encarecidamente establecer el parámetro de costo en un valor de al menos 12 para garantizar un nivel de seguridad suficiente. Este valor influye directamente en el tiempo necesario para calcular el hash, lo que hace que sea más costoso computacionalmente para los atacantes potenciales llevar a cabo ataques de fuerza bruta o de diccionario.

Abstract
El recuento de iteraciones que usa una función de derivación de clave basada en contraseña es demasiado bajo.
Explanation
Una función de derivación de claves se utiliza para derivar una clave a partir de una clave base y otros parámetros. En una función de derivación de claves basada en contraseña, la clave base es una contraseña y los otros parámetros son un valor de sal y un número de iteraciones. El número de iteraciones ha servido tradicionalmente para aumentar el coste de generar claves a partir de una contraseña. Si el recuento de iteraciones es demasiado bajo, la viabilidad de un ataque aumenta a medida que un atacante puede calcular "tablas de arcoíris" para la aplicación y determinar más fácilmente los valores de contraseña con hash.

Ejemplo 1: el código siguiente utiliza un recuento de iteraciones de 50:


...
let ITERATION = UInt32(50)
...
CCKeyDerivationPBKDF(CCPBKDFAlgorithm(kCCPBKDF2),
password,
passwordLength,
saltBytes,
saltLength,
CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256),
ITERATION,
derivedKey,
derivedKeyLength)
...


Las aplicaciones que usan un recuento de iteraciones bajo para el cifrado basado en contraseña son vulnerables a los ataques por diccionario, que son precisamente los ataques ante los cuales deberían proteger los esquemas de cifrado basados en contraseña.

Las aplicaciones que utilizan un número bajo de iteraciones para el cifrado basado en contraseñas están expuestas a ataques triviales basados en diccionarios, exactamente el tipo de ataque contra el cual se diseñaron los esquemas de cifrado basados en contraseñas.

Abstract
El código se salta la llamada a un paso necesario durante el proceso de generación de un hash criptográfico.
Explanation
La generación de valores de hash criptográficos implica varios pasos y saltarse un paso necesario compromete la intensidad de los valores de hash generados.

Ejemplo 1: el siguiente código se salta la llamada al método CL_ABAP_HMAC->UPDATE, lo que dará como resultado la creación de un hash basado en ningún dato:


...
DATA: obj TYPE REF TO cl_abap_hmac.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_key = 'ABCDEFG123456789'
RECEIVING
ro_object = obj.

obj->final( ).
....

Abstract
El código se salta la llamada a un paso necesario durante el proceso de generación de un hash criptográfico.
Explanation
La generación de valores de hash criptográficos implica varios pasos y saltarse un paso necesario compromete la intensidad de los valores de hash generados.

Ejemplo 1: el siguiente código se salta la llamada al método CryptCreateHash, lo que producirá la creación de un hash basado en ningún dato:


...
if(!CryptAcquireContext(&hCryptProv, NULL, MS_ENH_RSA_AES_PROV, PROV_RSA_AES, 0)) {
break;
}

if(!CryptHashData(hHash, (BYTE*)hashData, strlen(hashData), 0)) {
break;
}
...

Abstract
El uso de un algoritmo controlado por el usuario en un hash criptográfico puede permitir que un usuario malintencionado especifique un algoritmo de hash criptográfico débil y comprometa la seguridad y la integridad de los datos de la aplicación.
Explanation
Los problemas de Hash criptográfico débil: algoritmo controlado por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se utilizan para especificar el algoritmo de hash criptográfico.

Al igual que muchas vulnerabilidades de seguridad del software, Hash criptográfico débil: algoritmo controlado por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado transfiere datos malintencionados a una aplicación que, a continuación, se utilizan para especificar el algoritmo de hash criptográfico. Un usuario malintencionado podría especificar un algoritmo de hash como MD5, que tiene debilidades conocidas, y minar la seguridad y la integridad de los datos de la aplicación.

Ejemplo 1: el siguiente código utiliza un algoritmo controlado por el usuario:

...
string hashname = ConfigurationManager.AppSettings["hash"];
...
HashAlgorithm ha = HashAlgorithm.Create(hashname);
...


El código en el Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta función podrá manipular el algoritmo de hash modificando la propiedad hash. Una vez lanzado el programa, puede resultar muy difícil deshacer un problema relacionado con algoritmos controlados por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado el parámetro del algoritmo de un hash criptográfico específico.

Abstract
El uso de un algoritmo controlado por el usuario en un hash criptográfico puede permitir que un usuario malintencionado especifique un algoritmo de hash criptográfico débil y comprometa la seguridad y la integridad de los datos de la aplicación.
Explanation
Los problemas de Hash criptográfico débil: algoritmo controlado por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se utilizan para especificar el algoritmo de hash criptográfico.

Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: algoritmo controlado por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado pasa datos malintencionados a una aplicación, que a continuación se utilizan para especificar el algoritmo de hash criptográfico. Un usuario malintencionado podría especificar un algoritmo de hash como MD5, que tiene debilidades conocidas, y minar la seguridad y la integridad de los datos de la aplicación.

Ejemplo 1: el código siguiente utiliza un algoritmo controlado por el usuario:

...
Properties prop = new Properties();
prop.load(new FileInputStream("config.properties"));
String algorithm = prop.getProperty("hash");
...
MessageDigest messageDigest = MessageDigest.getInstance(algorithm);
messageDigest.update(hashInput.getBytes("UTF-8"));
...


El código en el Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta función podrá manipular el algoritmo de hash modificando la propiedad hash. Una vez lanzado el programa, puede resultar muy difícil deshacer un problema relacionado con algoritmos controlados por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado el parámetro del algoritmo de un hash criptográfico específico.

desc.dataflow.ruby.weak_cryptographic_hash_user_controlled_algorithm
Abstract
Un método que genera hashes criptográficos recibe un valor de bits mínimo a partir de la entrada del usuario.
Explanation
Esto podría permitir al atacante especificar un mínimo de bits vacíos, lo que hace posible una determinación más fácil de los valores de hash y una filtración de información sobre cómo el programa realiza su hash criptográfico. Los problemas de Hash criptográfico débil: Los problemas de bits mínimos controlados por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en los bits mínimos o se utilizan completamente como bits mínimos en una función de hash criptográfico.


Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: Los bits mínimos controlados por el usuario son un medio para lograr un fin, no un fin en sí mismos. Desde su raíz, la vulnerabilidad es sencilla: un atacante pasa datos malintencionados a una aplicación, que, a continuación, se utilizan como bits mínimos, totales o parciales, de una función de hash criptográfico.

Unos bits mínimos controlados por el usuario pueden permitir varios ataques:

1. Un atacante podría usar esta vulnerabilidad para especificar unos bits mínimos vacíos para los datos que se están procesando. Un atacante puede procesar rápidamente los datos que se están procesando mediante una serie de algoritmos de hash diferentes para filtrar información sobre la implementación de hash utilizada en su aplicación. Esto podría facilitar el "descifrado" de otros valores de datos limitando la variante específica de hash utilizada.
2. 2. Si un atacante puede manipular los bits mínimos de otros usuarios, o engañar a otros usuarios para que utilicen bits mínimos vacíos, esto le permite calcular "tablas arcoíris" para la aplicación y determinar fácilmente los valores con hash.

Ejemplo 1: El código siguiente utiliza bits mínimos controlados por el usuario para ejecutar un algoritmo hash en una contraseña:

...
String minimumBits = prop.getProperty("minimumbits");
Hashing.goodFastHash(minimumBits).hashString("foo", StandardCharsets.UTF_8);
...


El código en Example 1 se ejecuta correctamente, pero cualquier persona con acceso a esta funcionalidad puede manipular los bits mínimos utilizados para aplicar hash a la contraseña modificando la propiedad minimumBits. Una vez que se haya distribuido el programa, puede resultar difícil deshacer un problema relacionado con bits mínimos controlados por el usuario, dado que no puede saber si un usuario malintencionado ha configurado los bits mínimos del hash de la contraseña.

Abstract
Las entradas de usuario potencialmente contaminadas no deben pasarse como el parámetro de sal a una función de derivación de clave basada en contraseña (PBKDF).
Explanation
Los problemas de Hash criptográfico débil: Sal de PBE controlado por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en sal, o se utilizan completamente como sal de una función de derivación de clave basada en contraseña (PBKDF).


Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: sal de PBE controlado por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado transfiere datos dañinos a una aplicación y, a continuación, se utilizan como sal de una función PBKDF, total o parcialmente.

El problema de tener sal definida por el usuario es que puede posibilitar diversos ataques:

1. El atacante puede utilizar esta vulnerabilidad para especificar una sal vacía para su propia contraseña. A continuación, sería muy sencillo derivar rápidamente su propia contraseña utilizando distintas funciones de derivación de clave basada en contraseña para filtrar información sobre la implementación de la función PBKDF empleada en su aplicación. Esto podría hacer que "descifrar" otras contraseñas resultara más fácil al limitar la variante específica de hash utilizada.
2. Si el atacante puede manipular las sal de otros usuarios, o engañar a otros usuarios para que utilicen una sal vacía, esto podría permitirle calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores derivados.

Ejemplo 1: el siguiente código utiliza un sal controlado por el usuario:

string salt = ConfigurationManager.AppSettings["salt"];
...
Rfc2898DeriveBytes rfc = new Rfc2898DeriveBytes("password", Encoding.ASCII.GetBytes(salt));
...


El código en el Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta funcionalidad podrá manipular la sal utilizada para derivar la clave o la contraseña modificando la propiedad salt. Una vez que se haya distribuido el programa, puede resultar muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado la sal de un hash de contraseña.

Abstract
Las entradas de usuario potencialmente contaminadas no deben pasarse como el parámetro de sal a una función de derivación de clave basada en contraseña (PBKDF).
Explanation
Los problemas de Hash criptográfico débil: Los problemas de sal PBE controlada por el usuario se producen cuando ocurre lo siguiente:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en sal o se utilizan completamente como sal de una función de derivación de clave basada en contraseña (PBKDF).


Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: Sal PBE controlada por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado pasa datos dañinos a una aplicación, que a continuación se utilizan como sal de una función PBKDF, total o parcialmente.

El problema de tener sal definida por el usuario es que puede posibilitar diversos ataques:

1. El atacante puede utilizar esta vulnerabilidad para especificar una sal vacía para su propia contraseña. A continuación, sería muy sencillo derivar rápidamente su propia contraseña utilizando distintas funciones de derivación de clave basada en contraseña para filtrar información sobre la implementación de la función PBKDF empleada en su aplicación. Esto podría hacer que "descifrar" otras contraseñas resultara más fácil al limitar la variante específica de hash utilizada.
2. Si el atacante puede manipular las sal de otros usuarios, o engañar a otros usuarios para que utilicen una sal vacía, esto podría permitirle calcular "tablas arcoíris" para la aplicación y determinar más fácilmente los valores derivados.

Ejemplo 1: El código siguiente utiliza sal controlada por el usuario:

app.get('/pbkdf2', function(req, res) {
...
let salt = req.params['salt'];
crypto.pbkdf2(
password,
salt,
iterations,
keyLength,
"sha256",
function (err, derivedKey) { ... }
);
}


El código en el Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta funcionalidad podrá manipular la sal utilizada para derivar la clave o la contraseña modificando la propiedad salt. Una vez que se haya distribuido el programa, puede resultar muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado la sal de un hash de contraseña.

Abstract
Las entradas de usuario potencialmente contaminadas no deben pasarse como el parámetro de sal a una función de derivación de clave basada en contraseña (PBKDF).
Explanation
Los problemas de Hash criptográfico débil: sal de PBE controlado por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en sal, o se utilizan completamente como sal de una función de derivación de clave basada en contraseña (PBKDF).


Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: sal de PBE controlado por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado pasa datos dañinos a una aplicación, que a continuación se utilizan como sal de una función PBKDF, total o parcialmente.

El problema de tener sal definida por el usuario es que puede posibilitar diversos ataques:

1. El atacante puede utilizar esta vulnerabilidad para especificar una sal vacía para su propia contraseña. A continuación, sería muy sencillo derivar rápidamente su propia contraseña utilizando distintas funciones de derivación de clave basada en contraseña para filtrar información sobre la implementación de la función PBKDF empleada en su aplicación. Esto podría hacer que "descifrar" otras contraseñas resultara más fácil al limitar la variante específica de hash utilizada.
2. Si el atacante puede manipular las sal de otros usuarios, o engañar a otros usuarios para que utilicen una sal vacía, esto podría permitirle calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores derivados.

Ejemplo 1: el código siguiente utiliza sal controlada por el usuario:

import hashlib, binascii

def register(request):
password = request.GET['password']
username = request.GET['username']
salt = os.environ['SALT']

dk = hashlib.pbkdf2_hmac('sha256', password, salt, 100000)
hash = binascii.hexlify(dk)
store(username, hash)
...


El código del Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta funcionalidad podrá manipular la sal utilizada para derivar la clave o la contraseña modificando la variable de entorno SALT. Una vez que se haya distribuido el programa, puede resultar muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado la sal de un hash de contraseña.

1. El atacante puede utilizar esta vulnerabilidad para especificar una sal vacía para su propia contraseña. A continuación, sería muy sencillo derivar rápidamente su propia contraseña utilizando distintas funciones de derivación de clave basada en contraseña para filtrar información sobre la implementación de la función PBKDF empleada en su aplicación. Esto podría hacer que "descifrar" otras contraseñas resultara más fácil al limitar la variante específica de hash utilizada.
2. Si el atacante puede manipular las sal de otros usuarios, o engañar a otros usuarios para que utilicen una sal vacía, esto podría permitirle calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores derivados.

Ejemplo 1: El código siguiente utiliza sal controlada por el usuario:

...
@IBOutlet weak var inputTextField : UITextField!
...
let salt = (inputTextField.text as NSString).dataUsingEncoding(NSUTF8StringEncoding)
let saltPointer = UnsafePointer<UInt8>(salt.bytes)
let saltLength = size_t(salt.length)
...
let algorithm : CCPBKDFAlgorithm = CCPBKDFAlgorithm(kCCPBKDF2)
let prf : CCPseudoRandomAlgorithm = CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256)
CCKeyDerivationPBKDF(algorithm,
passwordPointer,
passwordLength,
saltPointer,
saltLength,
prf,
100000,
derivedKeyPointer,
derivedKeyLength)
...


El código en Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta funcionalidad podrá manipular la sal utilizada para derivar la clave o la contraseña modificando el texto de UITextField inputTextField. Una vez que se haya distribuido el programa, puede resultar muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado la sal de un hash de contraseña.

Abstract
A las funciones que generan valores de hash, a las que se pasa sal, no se les debe llamar con un argumento de sal contaminado.
Explanation
Los problemas de Hash criptográfico débil: sal controlada por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en sal o se utilizan completamente como sal de una función de hash criptográfico.

Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: sal controlada por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado pasa datos dañinos a una aplicación, que a continuación se utilizan como sal de un hash criptográfico, total o parcialmente.

El problema de tener sal controlada por el usuario es que puede posibilitar diversos ataques:

1. El atacante puede utilizar esta vulnerabilidad para especificar una sal vacía en los datos con hash. A continuación, sería muy sencillo usar su propio hash rápidamente en los datos utilizando distintos algoritmos de hash para filtrar información sobre la implementación de hash empleada en su aplicación. Esto podría facilitar el "descifrado" de otros valores de datos al limitar la variante específica de hash utilizada.
2. Si el atacante puede manipular las sal de otros usuarios, o engañar a otros usuarios para que utilicen una sal vacía, esto podría permitirle calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.

Ejemplo 1: el código siguiente utiliza sal controlada por el usuario para el hash de contraseña:

...
salt = getenv("SALT");
password = crypt(getpass("Password:"), salt);
...


El Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta función podrá manipular la sal utilizada para aplicar hash a la contraseña modificando la variable de entorno SALT. Además, este código utiliza la función crypt(), que no debería emplearse para el hash criptográfico de las contraseñas. Una vez que se haya distribuido el programa, puede resultar muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado la sal de un hash de contraseña.

Abstract
A los métodos que generan valores de hash criptográficos, a los que se pasa sal, no se les debe llamar con un argumento de sal contaminado.
Explanation
Los problemas de Hash criptográfico débil: sal controlada por el usuario se producen cuando:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en sal, o se utilizan completamente como sal en una función de hash criptográfico.


Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: sal controlada por el usuario es un medio para lograr un fin, no un fin en sí mismo. En su raíz, la vulnerabilidad es sencilla: un usuario malintencionado pasa datos dañinos a una aplicación, que a continuación se utilizan como sal de una función de hash criptográfico, total o parcialmente.

El problema de tener sal controlada por el usuario es que puede posibilitar diversos ataques:

1. El atacante puede utilizar esta vulnerabilidad para especificar una sal vacía en los datos con hash. A continuación, sería muy sencillo usar su propio hash rápidamente en los datos utilizando distintos algoritmos de hash para filtrar información sobre la implementación de hash empleada en su aplicación. Esto podría facilitar el "descifrado" de otros valores de datos al limitar la variante específica de hash utilizada.
2. Si el atacante puede manipular las sal de otros usuarios, o engañar a otros usuarios para que utilicen una sal vacía, esto podría permitirle calcular "tablas arco iris" para la aplicación y determinar más fácilmente los valores con hash.

Ejemplo 1: el código siguiente utiliza sal controlada por el usuario para el hash de contraseña:

...
Properties prop = new Properties();
prop.load(new FileInputStream("local.properties"));
String salt = prop.getProperty("salt");
...
MessageDigest digest = MessageDigest.getInstance("SHA-256");
digest.reset();
digest.update(salt);
return digest.digest(password.getBytes("UTF-8"));
...


El código del Example 1 se ejecutará correctamente, pero cualquier persona con acceso a esta función podrá manipular la sal utilizada para aplicar hash a la contraseña modificando la propiedad salt. Una vez que se haya distribuido el programa, puede resultar muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado ha determinado o no sal del hash de la contraseña.

Abstract
No acepte entradas del usuario para sal en métodos que generen hashes criptográficos.
Explanation
Los problemas de Hash criptográfico débil: sal controlada por el usuario se producen cuando ocurre lo siguiente:

1. Los datos entran en un programa a través de un origen que no es de confianza.

2. Los datos controlados por el usuario se incluyen en sal o se utilizan completamente como sal de una función de hash criptográfico.


Al igual que muchas vulnerabilidades de seguridad de software, Hash criptográfico débil: sal controlada por el usuario es un medio para lograr un fin, no un fin en sí mismo. En esta vulnerabilidad, un atacante puede pasar datos malintencionados a una aplicación, que a continuación se utilizan como sal, total o parcial, de una función de hash criptográfico.

Sal definida por el usuario puede habilitar varios tipos de ataque:

1. Los atacantes pueden utilizar esta vulnerabilidad para especificar una sal vacía en los datos con hash. Luego, los atacantes pueden usar su propio hash rápidamente en los datos utilizando muchos algoritmos distintos de hash para filtrar la implementación de hash de su aplicación. Esto podría facilitar el "descifrado" de otros valores de datos limitando la variante específica de hash utilizada.
2. Si un atacante puede manipular las sales de otros usuarios, o engañar a otros usuarios para que utilicen un una sal vacía, esto le permite calcular "tablas arcoíris" para la aplicación y determinar fácilmente los valores con hash.

Ejemplo 1: El siguiente código utiliza una sal controlada por el usuario para derivar una clave de cifrado:

let saltData = userInput.data(using: .utf8)

sharedSecret.hkdfDerivedSymmetricKey(
using: SHA256.self,
salt: saltData,
sharedInfo: info,
outputByteCount: 1000
)


El código del Ejemplo 1 se ejecutará correctamente, pero cualquier persona con acceso a esta funcionalidad puede manipular sal utilizada para derivar la clave de cifrado modificando el valor userInput. Una vez distribuido el programa, resulta muy difícil deshacer un problema relacionado con sal controlada por el usuario, dado que probablemente no habría forma de saber si un usuario malintencionado determinó sal de un hash de contraseña.

Abstract
La llamada identificada utiliza una primitiva criptográfica que contiene una debilidad introducida durante la implementación.
Explanation
Un error de software es un error en la implementación del software. Los errores se introducen por un sinfín de razones y son inevitables durante el desarrollo de software. Las implementaciones de algoritmos criptográficos no son una excepción. Estas implementaciones pueden contener errores que introducen vulnerabilidades en una aplicación. Las aplicaciones que se basan en implementaciones criptográficas inseguras son vulnerables a más ataques.

Abstract
No use el Algoritmo de firma digital.
Explanation
Una firma digital es una técnica utilizada para determinar la autenticidad y la integridad de los mensajes digitales. El Algoritmo de firma digital (DSA) ya está obsoleto y no debe usarse. A diferencia de otros algoritmos de firma digital, como RSA, DSA presenta una debilidad intrínseca. Requiere un valor secreto por mensaje k que debe ser criptográficamente aleatorio, mantenerse en secreto y que no debe reutilizarse nunca. Si un atacante puede adivinar el valor de k o engañar al firmante para que use un valor proporcionado en su lugar, puede recuperar la clave privada y luego falsificar cualquier firma, haciéndose pasar por el firmante legítimo. De manera similar, un atacante puede recuperar la clave privada si el valor de k se reutiliza para firmar varios mensajes.

Abstract
Un algoritmo de firma criptográfica que, en otras circunstancias, sería segura, se vuelve más vulnerable a los ataques por fuerza bruta cuando se utiliza un tamaño de clave insuficiente.
Explanation
Las instrucciones de criptografía actuales sugieren usar longitudes de claves de 2048 bits como mínimo con los algoritmos RSA y DSA. Sin embargo, los avances en la capacidad de cálculo y en las técnicas de factorización [1] hacen inevitables los futuros aumentos en el tamaño de clave recomendado.

Ejemplo 1: el siguiente código genera una clave de firma DSA de 1024 bits.

...
DSA dsa = new DSACryptoServiceProvider(1024);

Abstract
Un algoritmo de firma criptográfica que, en otras circunstancias, sería segura, se vuelve más vulnerable a los ataques por fuerza bruta cuando se utiliza un tamaño de clave insuficiente.
Explanation
Las instrucciones de criptografía actuales sugieren usar longitudes de claves de 2048 bits como mínimo con los algoritmos RSA y DSA. Sin embargo, los avances en la capacidad de cálculo y en las técnicas de factorización [1] hacen inevitables los futuros aumentos en el tamaño de clave recomendado.

Ejemplo 1: el siguiente código genera una clave de firma DSA de 1024 bits.

...
from Crypto.PublicKey import DSA
key = DSA.generate(1024)
...

Abstract
El código se salta la llamada a un paso necesario durante el proceso de generación de una firma criptográfica.
Explanation
La generación de firmas criptográficas implica varios pasos y saltarse un paso necesario compromete la seguridad de las firmas generadas.

Ejemplo 1: el siguiente código se salta la llamada al método EVP_SignUpdate, lo que producirá la creación de una firma basada en ningún dato:


...
rv = EVP_SignInit(ctx, EVP_sha512());
...
rv = EVP_SignFinal(ctx, sig, &sig_len, key);
...

Abstract
El código se salta la llamada a un paso necesario durante el proceso de generación de una firma criptográfica.
Explanation
La generación de firmas criptográficas implica varios pasos y saltarse un paso necesario compromete la seguridad de las firmas generadas.

Ejemplo 1: el siguiente código se salta la llamada al método update, lo que producirá la creación de una firma basada en ningún dato:

...
Signature sig = Signature.getInstance("SHA256withRSA");
sig.initSign(keyPair.getPrivate());
...
byte[] signatureBytes = sig.sign();
...

Abstract
El código deshabilita la validación segura de la firma XML.
Explanation
El modo de validación segura de la firma XML permite la validación de firmas digitales XML y restringe varias construcciones XML para evitar ciertas denegaciones de servicio y otros tipos de ataques.

Estas restricciones incluyen:
- Prohíbe el uso de transformaciones XSLT.
- Restringe el número de elementos SignedInfo o Manifest Reference a 30 o menos.
- Restringe el número de transformaciones de referencia a 5 o menos.
- Prohíbe el uso de firmas MD5 o algoritmos MAC MD5.
- Garantiza que los ID de referencia sean únicos para ayudar a prevenir ataques de envoltura de firmas.
- Prohíbe URI de referencia de tipo http, https o archivo.
- No permite que un elemento RetrievalMethod haga referencia a otro elemento RetrievalMethod.
- Prohíbe claves RSA o DSA de menos de 1024 bits.
- Prohíbe claves EC de menos de 224 bits.

Ejemplo 1: El siguiente código deshabilita la validación segura de la firma XML con una propiedad del sistema:

Properties props = System.getProperties();
...
properties.setProperty("org.jcp.xml.dsig.secureValidation", "false");
Ejemplo 2: El siguiente código deshabilita la validación segura de la firma XML con XMLCryptoContext.setProperty:

DOMCryptoContext cryptoContext = new DOMCryptoContext() {...};
...
cryptoContext.setProperty("org.jcp.xml.dsig.secureValidation", false);

Abstract
La llamada identificada utiliza un algoritmo de cifrado débil que no puede garantizar la confidencialidad de los datos confidenciales.
Explanation
Los algoritmos de cifrado anticuados como DES dejarán de ofrecer una protección suficiente para su uso con los datos confidenciales. Los algoritmos de cifrado se basan en el tamaño de la clave como uno de los mecanismos principales para garantizar la intensidad criptográfica. La intensidad criptográfica a menudo se mide por el tiempo y la capacidad computacional de cálculo necesarios para generar una clave válida. Los avances en la capacidad de cálculo han hecho posible obtener claves de cifrado pequeñas en un período de tiempo razonable. Por ejemplo, la clave de 56 bits utilizada en DES supuso un importante obstáculo computacional en la década de 1970, cuando se desarrolló por primera vez el algoritmo. Actualmente, DES se puede descifrar en menos de un día con equipos de uso generalizado.

Abstract
La llamada identificada utiliza un algoritmo de cifrado débil que no puede garantizar la confidencialidad de los datos confidenciales.
Explanation
Los algoritmos de cifrado anticuados como DES dejarán de ofrecer una protección suficiente para su uso con los datos confidenciales. Los algoritmos de cifrado se basan en el tamaño de la clave como uno de los mecanismos principales para garantizar la intensidad criptográfica. La intensidad criptográfica a menudo se mide por el tiempo y la capacidad computacional de cálculo necesarios para generar una clave válida. Los avances en la capacidad de cálculo han hecho posible obtener claves de cifrado pequeñas en un período de tiempo razonable. Por ejemplo, la clave de 56 bits utilizada en DES supuso un importante obstáculo computacional en la década de 1970, cuando se desarrolló por primera vez el algoritmo. Actualmente, DES se puede descifrar en menos de un día con equipos de uso generalizado.

Abstract
La llamada identificada utiliza un algoritmo de cifrado débil que no puede garantizar la confidencialidad de los datos confidenciales.
Explanation
Los algoritmos de cifrado anticuados como DES dejarán de ofrecer una protección suficiente para su uso con los datos confidenciales. Los algoritmos de cifrado se basan en el tamaño de la clave como uno de los mecanismos principales para garantizar la intensidad criptográfica. La intensidad criptográfica a menudo se mide por el tiempo y la capacidad computacional de cálculo necesarios para generar una clave válida. Los avances en la capacidad de cálculo han hecho posible obtener claves de cifrado pequeñas en un período de tiempo razonable. Por ejemplo, la clave de 56 bits utilizada en DES supuso un importante obstáculo computacional en la década de 1970, cuando se desarrolló por primera vez el algoritmo. Actualmente, DES se puede descifrar en menos de un día con equipos de uso generalizado.

Abstract
La llamada identificada utiliza un algoritmo de cifrado débil que no puede garantizar la confidencialidad de los datos confidenciales.
Explanation
Los algoritmos de cifrado anticuados, especialmente los que usan claves de tamaño insuficiente, ya no ofrecen protección suficiente para datos confidenciales, ya que los avances tecnológicos permiten obtener claves de cifrado pequeñas en un período de tiempo razonable mediante ataques por fuerza bruta. Por ejemplo, la clave de 64 bits utilizada en DES supuso un importante obstáculo computacional en la década de 1970 cuando se desarrolló por primera vez el algoritmo, pero hoy en día DES se puede descifrar en menos de un día con equipos de uso generalizado.

Ejemplo 1: el código siguiente realiza el cifrado con un algoritmo inseguro (DES):

...
CCCrypt(kCCEncrypt,
kCCAlgorithmDES,
kCCOptionPKCS7Padding,
key,
kCCKeySizeDES, // 64-bit key size
iv,
plaintext,
sizeof(plaintext),
ciphertext,
sizeof(ciphertext),
&numBytesEncrypted);
...

Abstract
La llamada identificada utiliza un algoritmo de cifrado débil que no puede garantizar la confidencialidad de los datos confidenciales.
Explanation
Los algoritmos de cifrado anticuados como DES dejarán de ofrecer una protección suficiente para su uso con los datos confidenciales. Los algoritmos de cifrado se basan en el tamaño de la clave como uno de los mecanismos principales para garantizar la intensidad criptográfica. La intensidad criptográfica a menudo se mide por el tiempo y la capacidad computacional de cálculo necesarios para generar una clave válida. Los avances en la capacidad de cálculo han hecho posible obtener claves de cifrado pequeñas en un período de tiempo razonable. Por ejemplo, la clave de 56 bits utilizada en DES supuso un importante obstáculo computacional en la década de 1970, cuando se desarrolló por primera vez el algoritmo. Actualmente, DES se puede descifrar en menos de un día con equipos de uso generalizado.

Abstract
La llamada identificada utiliza un algoritmo de cifrado débil que no puede garantizar la confidencialidad de los datos confidenciales.
Explanation
Los algoritmos de cifrado anticuados, especialmente los que usan claves de tamaño insuficiente, ya no ofrecen protección suficiente para datos confidenciales, ya que los avances tecnológicos permiten obtener claves de cifrado pequeñas en un período de tiempo razonable mediante ataques por fuerza bruta. Por ejemplo, la clave de 64 bits utilizada en DES supuso un importante obstáculo computacional en la década de 1970, cuando se desarrolló por primera vez el algoritmo. Actualmente, DES se puede descifrar en menos de un día con equipos de uso generalizado.

Ejemplo 1: el código siguiente realiza el cifrado con un algoritmo inseguro (DES):

...
let iv = getTrueRandomIV()
...
let cStatus = CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmDES),
UInt32(kCCOptionPKCS7Padding),
key,
keyLength,
iv,
plaintext,
plaintextLength,
ciphertext,
ciphertextLength,
&numBytesEncrypted)
...

Abstract
Convertir una clave de cifrado en String puede suponer una pérdida significativa de entropía.
Explanation
Los problemas de Cifrado débil: matriz de bytes a conversión de cadena se producen cuando:

1. Se crea una clave de cifrado como matriz de bytes


2. Los datos se convierten en String.

Ejemplo 1: el siguiente código crea una clave de cifrado y, a continuación, la convierte en String.


import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
...
KeyGenerator keygen = KeyGenerator.newInstance("AES");
...
SecretKey cryptoKey = keygen.generateKey();
byte[] rawCryptoKey = cryptoKey.getEncoded();
...
String key = new String(rawCryptoKey);
...


Esto convierte una clave criptográfica en String utilizando el conjunto de caracteres del sistema predeterminado. Sin embargo, no se especifica lo que ocurre cuando se da al constructor bytes fuera del rango válido de este conjunto de caracteres. De esta forma, key ocasionará una pérdida significativa de entropía en comparación con la clave de cifrado original rawCryptoKey.

Abstract
El cifrado RSA de clave pública se realiza sin relleno de OAEP, lo que debilita el cifrado.
Explanation
En la práctica, el cifrado con una clave pública RSA se suele combinar con un esquema de relleno. Un esquema de relleno puede impedir ataques contra RSA que solo funcionan cuando el cifrado se realiza sin relleno.

Ejemplo 1: El código siguiente realiza el cifrado con una clave pública RSA sin utilizar un esquema de relleno:

public Cipher getRSACipher() {
Cipher rsa = null;
try {
rsa = javax.crypto.Cipher.getInstance("RSA/NONE/NoPadding");
}
catch (java.security.NoSuchAlgorithmException e) {
log("this should never happen", e);
}
catch (javax.crypto.NoSuchPaddingException e) {
log("this should never happen", e);
}
return rsa;

Abstract
El cifrado RSA de clave pública se realiza sin relleno de OAEP, lo que debilita el cifrado.
Explanation
En la práctica, el cifrado con una clave pública RSA se suele combinar con un esquema de relleno. Un esquema de relleno puede impedir ataques contra RSA que solo funcionan cuando el cifrado se realiza sin relleno.

Ejemplo 1: El código siguiente realiza el cifrado con una clave pública RSA sin utilizar un esquema de relleno:

require 'openssl'
...
key = OpenSSL::PKey::RSA.new 2048
public_encrypted = key.public_encrypt(data) #padding type not specified
...


En el Example 1, OpenSSL::PKey::RSA#public_encrypt solo se llama con una cadena y no especifica el tipo de relleno a utilizar. El relleno se establece de forma predeterminada en OpenSSL::PKey::RSA::PKCS1_PADDING.
