Abstract
La aplicación omite la autorización otorgada por el atributo [Authorize] con el uso de un atributo [AllowAnonymous] de clase o método.
Explanation
ASP.NET Core permite que las acciones de la aplicación requieran autorización agregando el atributo [Authorize] a una clase o un método. Además, el requisito de autorización especificado de una clase o método de aplicación se puede omitir agregando el atributo [AllowAnonymous]. Cuando se especifican ambos, el atributo [AllowAnonymous] tiene prioridad y omite el atributo [Authorize]. Esto puede resultar en el acceso arbitrario y anónimo a datos y acciones confidenciales por parte de un atacante.

Ejemplo 1: El siguiente ejemplo muestra el atributo [AllowAnonymous] de clase anulando un conjunto de atributos [Authorize] en el método. El método secretAction() no requiere autorización a pesar de tener el atributo [Authorize].


...
[AllowAnonymous]
public class Authorization_Test
{
[Authorize]
public IActionResult secretAction()
{

}
}
...
Ejemplo 2: El siguiente ejemplo muestra el atributo [AllowAnonymous] de clase de una superclase anulando un atributo [Authorize] establecido en el método de una subclase. Debido a que la clase heredada Inherit_AA tiene el atributo [AllowAnonymous], el método secretAction() no requiere autorización a pesar de especificar el atributo [Authorize].


...
[AllowAnonymous]
public abstract class Inherit_AA
{

}

public class Authorization_Test:Inherit_AA
{
[Authorize]
public IActionResult secretAction()
{

}
}
...
Ejemplo 3: A continuación, se muestra el atributo [AllowAnonymous] que anula un atributo [Authorize] de método con herencia. Debido a que el método heredado secretAction() tiene el atributo [AllowAnonymous], el método secretAction() no requiere autorización, a pesar de especificar el atributo [Authorize] en el método de anulación.


...
public abstract class Inherit_AA
{
[AllowAnonymous]
public abstract IActionResult secretAction()
{

}
}

public class Authorization_Test:Inherit_AA
{
[Authorize]
public override IActionResult secretAction()
{

}
}
...

Abstract
Sin un control de acceso adecuado, la ejecución de una instrucción LDAP que contiene un valor controlado por el usuario puede permitir a un atacante acceder a registros no autorizados.
Explanation
La ejecución de consultas LDAP bajo un enlace anónimo, sin autenticación efectiva, puede permitir a un atacante abusar de un entorno LDAP configurado incorrectamente.

Ejemplo 1: El código siguiente crea la DirectoryEntry de mediante un enlace anónimo.


...
de = new DirectoryEntry("LDAP://ad.example.com:389/ou=People,dc=example,dc=com");
...


Todas las consultas LDAP ejecutadas contra de se realizarán sin autenticación ni control de acceso. Un atacante puede ser capaz de manipular una de estas consultas de forma inesperada para obtener acceso a registros que, de otro modo, estarían protegidos por el mecanismo de control de acceso del directorio.

Abstract
Sin un control de acceso adecuado, la ejecución de una instrucción LDAP que contiene un valor controlado por el usuario puede permitir a un atacante acceder a registros no autorizados.
Explanation
La ejecución de consultas LDAP bajo un enlace anónimo, sin autenticación efectiva, puede permitir a un atacante abusar de un entorno LDAP configurado incorrectamente.

Ejemplo 1: el código siguiente usa ldap_simple_bind_s() para vincularse de forma anónima a un directorio LDAP.


...
rc = ldap_simple_bind_s( ld, NULL, NULL );
if ( rc != LDAP_SUCCESS ) {
...
}
...


Todas las consultas LDAP ejecutadas contra ld se realizarán sin autenticación ni control de acceso. Un atacante puede ser capaz de manipular una de estas consultas de forma inesperada para obtener acceso a registros que, de otro modo, estarían protegidos por el mecanismo de control de acceso del directorio.

desc.dataflow.cpp.access_control_anonymous_ldap_bind
Abstract
Sin un control de acceso adecuado, la ejecución de una instrucción LDAP que contiene un valor controlado por el usuario puede permitir a un atacante acceder a registros no autorizados.
Explanation
La ejecución de consultas LDAP bajo un enlace anónimo, sin autenticación efectiva, puede permitir a un atacante abusar de un entorno LDAP configurado incorrectamente.

Ejemplo 1: El código siguiente crea la DirContext ctx mediante un enlace anónimo.


...
env.put(Context.SECURITY_AUTHENTICATION, "none");
DirContext ctx = new InitialDirContext(env);
...


Todas las consultas LDAP ejecutadas contra ctx se realizarán sin autenticación ni control de acceso. Un atacante puede ser capaz de manipular una de estas consultas de forma inesperada para obtener acceso a registros que, de otro modo, estarían protegidos por el mecanismo de control de acceso del directorio.

Abstract
Sin un control de acceso adecuado, la ejecución de una declaración LDAP que contiene un valor controlado por el usuario puede proporcionar a un atacante acceso a registros no autorizados.
Explanation
La ejecución de consultas LDAP bajo un enlace anónimo, efectivamente sin autenticación, puede permitir que un atacante abuse de un entorno LDAP mal configurado.

Ejemplo 1: El siguiente código crea un enlace anónimo si el usuario ingresa una contraseña vacía.


...
$ldapbind = ldap_bind ($ldap, $dn, $password = "" );

desc.semantic.php.access_control_anonymous_ldap_bind
Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el código siguiente utiliza una instrucción que se basa en un número entero y, por tanto, no es vulnerable a las vulnerabilidades de SQL Injection, para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.


DATA: id TYPE i.
...
id = request->get_form_field( 'invoiceID' ).

CONCATENATE `INVOICEID = '` id `'` INTO cl_where.
SELECT *
FROM invoices
INTO CORRESPONDING FIELDS OF TABLE itab_invoices
WHERE (cl_where).
ENDSELECT.
...


El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de ID. Aunque la interfaz genera una lista de identificadores de factura que pertenecen al usuario actual, un atacante puede eludir esta interfaz para solicitar cualquier factura que desee. Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el siguiente código utiliza una instrucción parametrizada, que aplica caracteres de escape a metacaracteres e impide la inclusión de vulnerabilidades de SQL Injection, para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var id:int = int(Number(params["invoiceID"]));
var query:String = "SELECT * FROM invoices WHERE id = :id";

stmt.sqlConnection = conn;
stmt.text = query;
stmt.parameters[":id"] = id;
stmt.execute();
...


El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de id. Aunque la interfaz genera una lista de identificadores de factura que pertenecen al usuario actual, un atacante puede eludir esta interfaz para solicitar cualquier factura que desee. Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SOQL/SOSL que puede contener una clave principal proporcionada por el usuario, se puede permitir al atacante ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SOQL/SOSL.
Ejemplo 1: en el siguiente ejemplo de código, el valor inputID se origina a partir de una lista definida previamente, y una variable de enlace contribuye a evitar la inyección de SOQL/SOSL.


...
result = [SELECT Name, Phone FROM Contact WHERE (IsDeleted = false AND Id=:inputID)];
...


El problema con el ejemplo anterior es que el uso de una lista de identificadores definida previamente no es suficiente para evitar que el usuario modifique el valor de inputID. Si el atacante es capaz de evitar la interfaz y enviar una solicitud con un valor diferente, tendrá acceso a otra información de contacto. Dado que el código en este ejemplo no realiza una comprobación para asegurarse de que el usuario tiene permiso para acceder al contacto solicitado, se mostrará cualquier contacto, incluso si el usuario no tiene permiso para verlo.

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: el siguiente código utiliza una instrucción parametrizada, que establece secuencias de escape metacaracteres e impide las vulnerabilidades de SQL Injection, para crear y ejecutar una consulta SQL que busca una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.


...
ACCEPT ID.
EXEC SQL
DECLARE C1 CURSOR FOR
SELECT INVNO, INVDATE, INVTOTAL
FROM INVOICES
WHERE INVOICEID = :ID
END-EXEC.
...


El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de ID. Aunque la interfaz genera una lista de identificadores de factura que pertenecen al usuario actual, un atacante puede eludir esta interfaz para solicitar cualquier factura que desee. Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Example 1: The following code uses a parameterized statement, which escapes metacharacters and prevents SQL injection vulnerabilities, to construct and execute a SQL query that searches for an invoice matching the specified identifier [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.


...
id = Integer.decode(request.getParameter("invoiceID"));
String query = "SELECT * FROM invoices WHERE id = ?";
PreparedStatement stmt = conn.prepareStatement(query);
stmt.setInt(1, id);
ResultSet results = stmt.execute();
...


El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de id. Aunque la interfaz genera una lista de identificadores de factura que pertenecen al usuario actual, un atacante puede eludir esta interfaz para solicitar cualquier factura que desee. Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.

Algunos piensan que en el mundo de las plataformas móviles, las vulnerabilidades de las aplicaciones web clásicas, como los errores de control de acceso a bases de datos, no tienen ningún sentido: ¿por qué se atacaría un usuario a sí mismo? Sin embargo, tenga en cuenta que la esencia de las plataformas móviles consiste en aplicaciones que se descargan desde varias fuentes y se ejecutan junto con otras en el mismo dispositivo. La probabilidad de ejecutar un malware junto a una aplicación de banca es bastante alta, de modo que se necesita expandir la superficie expuesta a ataques de las aplicaciones móviles para que incluyan las comunicaciones entre procesos.

Ejemplo 2: el siguiente código adapta el Example 1 a la plataforma Android.


...
String id = this.getIntent().getExtras().getString("invoiceID");
String query = "SELECT * FROM invoices WHERE id = ?";
SQLiteDatabase db = this.openOrCreateDatabase("DB", MODE_PRIVATE, null);
Cursor c = db.rawQuery(query, new Object[]{id});
...


Varios marcos web modernos proporcionan mecanismos para realizar la validación de la entrada del usuario (entre ellos, Struts y Struts 2). Para resaltar los orígenes no validados de entrada, los Paquetes de reglas de codificación segura de Fortify vuelven a priorizar dinámicamente los problemas notificados por Fortify Static Code Analyzer reduciendo la probabilidad de ataques y ofreciendo argumentos para los elementos probatorios cada vez que el mecanismo de validación de la estructura está en uso. Esta característica recibe el nombre de clasificación basada en contexto. A modo de ayuda extra para el usuario de Fortify con el proceso de auditoría, Fortify Software Security Research Group facilita la plantilla de proyecto de validación de datos que agrupa los problemas en carpetas en función del mecanismo de validación aplicado al origen de la entrada.

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contiene una clave principal que el usuario malintencionado controla, se puede permitir a este ver los registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Example 1: The following code uses a parameterized statement, which escapes metacharacters and prevents SQL injection vulnerabilities, to construct and execute a SQL query that searches for an invoice matching the specified identifier [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.


...
$id = $_POST['id'];
$query = "SELECT * FROM invoices WHERE id = ?";
$stmt = $mysqli->prepare($query);
$stmt->bind_param('ss',$id);
$stmt->execute();
...


El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de id. Aunque la interfaz genera una lista de identificadores de factura que pertenecen al usuario actual, un atacante puede eludir esta interfaz para solicitar cualquier factura que desee. Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.

Varios marcos web modernos proporcionan mecanismos para realizar la validación de la entrada del usuario (entre ellos, Struts y Struts 2). Para resaltar los orígenes no validados de entrada, los Paquetes de reglas de codificación segura de Fortify vuelven a priorizar dinámicamente los problemas notificados por Fortify Static Code Analyzer reduciendo la probabilidad de ataques y ofreciendo argumentos para los elementos probatorios cada vez que el mecanismo de validación de la estructura está en uso. Esta característica recibe el nombre de clasificación basada en contexto. A modo de ayuda extra para el usuario de Fortify con el proceso de auditoría, Fortify Software Security Research Group facilita la plantilla de proyecto de validación de datos que agrupa los problemas en carpetas en función del mecanismo de validación aplicado al origen de la entrada.

Abstract
Sin el control de acceso adecuado, al ejecutar una instrucción SQL que contenga una clave principal controlada por el atacante, se puede permitir a este ver registros no autorizados.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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


2. Los datos se utilizan para especificar el valor de una clave principal en una consulta SQL.
Ejemplo 1: El siguiente código utiliza una instrucción parametrizada, la cual establece secuencias de escape para los metacaracteres e impide las vulnerabilidades SQL Injection, para crear y ejecutar una consulta SQL que busque una factura que coincida con el identificador especificado [1]. El identificador se selecciona de una lista de todas las facturas asociadas al usuario autenticado actual.


def searchInvoice(value:String) = Action.async { implicit request =>
val result: Future[Seq[Invoice]] = db.run {
sql"select * from invoices where id=$value".as[Invoice]
}
...
}


El problema es que el desarrollador no ha tenido en cuenta todos los valores posibles de id. Aunque la interfaz genera una lista de identificadores de factura que pertenecen al usuario actual, un atacante puede eludir esta interfaz para solicitar cualquier factura que desee. Dado que el código de este ejemplo no comprueba si el usuario tiene permiso para acceder a la factura solicitada, se mostrará cualquier factura, incluso si no pertenece al usuario actual.

Abstract
La aplicación establece una propiedad que permite la entrada no validada a las API nativas y puede llevar a que un atacante eluda la autenticación.
Explanation
De forma predeterminada, la autenticación de formularios ASP.NET valida las credenciales del usuario antes de pasarlas a las API nativas durante el proceso de autenticación. El problema es que esta funcionalidad se puede modificar con el parámetro aspnet:UseLegacyFormsAuthenticationTicketCompatibility para permitir que entradas no validadas se pasen a las API nativas y puede llevar a que un atacante pueda eludir la autenticación. Un atacante que aproveche con éxito esta vulnerabilidad podría eludir la autenticación de formularios ASP.NET para cualquier nombre de usuario conocido sin su contraseña. El atacante podría entonces realizar cualquier acción en el contexto del usuario víctima, incluida la ejecución de comandos arbitrarios en el sitio.

Ejemplo 1: en el siguiente ejemplo, aspnet:UseLegacyFormsAuthenticationTicketCompatibility está definido como true.

...
<appSettings>
<add key="aspnet:UseLegacyFormsAuthenticationTicketCompatibility" value="true" />
</appSettings>
...

Abstract
Sin un control de acceso adecuado, la ejecución de una instrucción LDAP que contenga un valor controlado por el usuario puede permitir a un atacante acceder a entradas de directorio no autorizadas.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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

2. Los datos se utilizan para especificar un valor de datos en una consulta LDAP.
Ejemplo 1: el ID de empleado del usuario actualmente autenticado se envía de forma automática con cada solicitud mediante la interfaz de cliente. El código siguiente valida adecuadamente el nombre de empleado mediante una lista de permitidos antes de utilizarlo para crear una consulta LDAP. Esta validación impide la aparición de vulnerabilidades LDAP Injection, pero podría seguir dejando al código vulnerable.


static string AllowlistVerify(string name) {
Regex pattern = new Regex(@"^[a-zA-Z\-\.']+$");
if (pattern.IsMatch(name)) {
return name;
}
return null;
}

...
string verifiedName = AllowlistVerify(managerName.Text.trim());
if(verifiedName != null) {
DirectorySearcher src = new DirectorySearcher("(manager=" + verifiedName + ")");
src.SearchRoot = de;
src.SearchScope = SearchScope.Subtree;

foreach(SearchResult res in src.FindAll()) {
...
}
}


El problema es que el desarrollador no ha tenido en cuenta qué pasaría si un atacante proporciona valores alternativos de empName. Aunque la interfaz envíe automáticamente el ID de empleado al usuario actual, un atacante podría enviar un valor alternativo como parte de una solicitud maliciosa. Como el código de este ejemplo ejecuta la consulta bajo un vínculo anónimo, devolverá la entrada de directorio para un ID de empleado válido, independientemente de la identidad del usuario autenticado actualmente.

Abstract
Sin un control de acceso adecuado, la ejecución de una instrucción LDAP que contenga un valor controlado por el usuario puede permitir a un atacante acceder a entradas de directorio no autorizadas.
Explanation
Se producen errores de control de acceso de base de datos cuando:

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

2. Los datos se utilizan para especificar un valor de datos en una consulta LDAP.
Ejemplo 1: El ID de empleado del usuario actualmente autenticado se envía automáticamente con cada solicitud mediante la interfaz de cliente. El código siguiente valida un ID de empleado como un entero antes de usarlo para construir una consulta LDAP. Esta validación impide la aparición de vulnerabilidades de inserción LDAP, pero podría seguir dejando al código vulnerable.


...
env.put(Context.SECURITY_AUTHENTICATION, "none");
DirContext ctx = new InitialDirContext(env);

String empID = request.getParameter("empID");

try
{
int id = Integer.parseInt(empID);

BasicAttribute attr = new BasicAttribute("empID", empID);

NamingEnumeration employee =
ctx.search("ou=People,dc=example,dc=com",attr);
...



El problema es que el desarrollador no ha tenido en cuenta qué pasaría si un atacante proporciona valores alternativos de empID. Aunque la interfaz envíe automáticamente el ID de empleado al usuario actual, un atacante podría enviar un valor alternativo como parte de una solicitud maliciosa. Como el código de este ejemplo ejecuta la consulta bajo un vínculo anónimo, devolverá la entrada de directorio para un ID de empleado válido, independientemente de la identidad del usuario autenticado actualmente.

Abstract
La aplicación permite una compresión peligrosa.
Explanation

La aplicación utiliza código que habilita la extensión WebSocket de deflación de mensajes que permite la compresión a través de conexiones cifradas. La habilitación de este tipo de compresión hace que la aplicación esté sujeta a ataques de tipo CRIME y BREACH.

Ejemplo 1: El siguiente código establece DangerousEnableCompression en true para habilitar la extensión "per-message-deflate":

app.Run(async context => {
using var websocket = await context.WebSockets.AcceptWebSocketAsync(new WebSocketAcceptContext() { DangerousEnableCompression = true });
await websocket.SendAsync(...);
await websocket.ReceiveAsync(...);
await websocket.CloseAsync(WebSocketCloseStatus.NormalClosure, null, default);
});
Ejemplo 2: El siguiente código utiliza DangerousDeflateOptions para configurar las opciones para la extensión "per-message-deflate":

using ClientWebSocket ws = new() {
Options = {
CollectHttpResponseDetails = true,
DangerousDeflateOptions = new WebSocketDeflateOptions() {
ClientMaxWindowBits = 10,
ServerMaxWindowBits = 10
}
}
};

Abstract
El almacenamiento de un objeto no serializable como un atributo HttpSessionState puede dañar la confiabilidad de la aplicación.
Explanation
De forma predeterminada, los servidores de ASP.NET almacenan el objeto HttpSessionState, sus atributos y cualquier objeto al que hagan referencia en la memoria. Este modelo limita el estado de sesiones activas que puede alojar la memoria del sistema de un solo equipo. Para ampliar la capacidad más allá de estas limitaciones, los servidores se configuran con frecuencia para almacenar la información de estado de sesión, lo que permite ampliar la capacidad y efectuar la replicación entre varios equipos a fin de mejorar el rendimiento general. Para almacenar su estado de sesión, el servidor debe serializar el objeto HttpSessionState, para lo que es necesario que todos los objetos almacenados sean serializables.

Para poder serializar la sesión correctamente, todos los objetos que almacena la aplicación como atributos de sesión deben declarar el atributo [Serializable]. Además, si el objeto requiere métodos de serialización personalizados, también debe implementar la interfaz ISerializable.

Ejemplo 1: la siguiente clase se añade a sí misma a la sesión, pero como no es serializable, la sesión no se puede serializar correctamente.


public class DataGlob {
String GlobName;
String GlobValue;

public void AddToSession(HttpSessionState session) {
session["glob"] = this;
}
}

Abstract
Se ha incluido JavaScript no minimizado en este archivo. Microsoft recomienda incluir las versiones minimizadas de las bibliotecas JavaScript por motivos de rendimiento.
Explanation
La minimización mejora los tiempos de carga de páginas para las aplicaciones que incluyen archivos JavaScript al reducir su tamaño. La minimización hace referencia al proceso de eliminación de espacios en blanco, comentarios, signos de punto y coma, y llaves acortando el nombre de las variables locales y eliminando código inaccesible.

Ejemplo 1: en el siguiente código ASPX se incluye la versión no minimizada de la biblioteca jQuery de Microsoft:


...
<script src="http://applicationserver.application.com/lib/jquery/jquery-1.4.2.js" type="text/javascript"></script>

Abstract
Los métodos de acción de API web ASP.NET que reciben un modelo deben comprobar si la validación del modelo es correcta para evitar vulnerabilidades que puedan resultar de entradas sin comprobar.
Explanation
Las entradas sin validar son una de las principales causas de vulnerabilidades en los servicios de API web ASP.NET. Las entradas no comprobadas pueden llevar a muchas vulnerabilidades, incluidas Cross-Site Scripting, Process Control, Access Control y SQL Injection, entre otras. Aunque los servicios de API web ASP.NET normalmente no son susceptibles de ataques de corrupción de memoria, si un servicio de API web ASP.NET llama en código nativo que no realiza comprobaciones de enlaces de matriz, un atacante puede utilizar una debilidad de validación de entrada del servicio de API web ASP.NET para iniciar un ataque de buffer overflow.

Para evitar ataques de este tipo:
1. Utilice atributos de validación para anotar comprobaciones de validación mediante programación en parámetros o miembros de parámetros de objeto de enlace de modelos para acciones del servicio de API web ASP.NET.
2. Utilice ModelState.IsValid para comprobar si la validación del modelo es correcta.

Abstract
La suplantación de las credenciales de usuario podría permitir a un usuario malintencionado obtener acceso no autorizado a recursos protegidos.
Explanation
Las aplicaciones Microsoft ASP.NET pueden suplantar el contexto de seguridad del usuario actual o el proceso que las llama para ejecutar operaciones con privilegios. Aunque los contextos de suplantación presentan diversos fines útiles como, por ejemplo, la reducción del número general de intentos de autenticación que debe realizarse, un programa que mantenga privilegios elevados plantea de forma innecesaria un riesgo para la seguridad general del sistema. Si un usuario malintencionado explota otra vulnerabilidad en el programa mientras se ejecuta en otro contexto de seguridad, todas las operaciones no autorizadas que realice este usuario se ejecutarán con los privilegios correspondientes.

Ejemplo 1: el siguiente ejemplo de código representa un patrón de uso típico de suplantación de credenciales mediante el método WindowsIdentity.Impersonate().


using System.Security.Principal;
...

//Get the identity of the current user
IIdentity contextId = HttpContext.Current.User.Identity;
WindowsIdentity userId = (WindowsIdentity)contextId;

//Temporarily impersonate
WindowsImpersonationContext imp = userId.Impersonate();

//Perform tasks using the caller's security context
DoSecuritySensitiveTasks();

//Clean up and restore our old security context
impersonate.Undo();


El código del Example 1 suplanta el contexto de seguridad del usuario actual y lo utiliza para realizar una operación con privilegios. Después de llamar a DoSecuritySensitiveTasks(), el código intenta restablecer el contexto de seguridad original, pero, si DoSecuritySensitiveTasks() genera una excepción, no se llamará nunca al método Undo(), por lo que el programa seguirá usando el contexto de seguridad suplantado.

Abstract
La aplicación especifica incorrectamente el middleware de la política de cookies de ASP.NET.
Explanation
El middleware ASP.NET Core que no se agrega a la canalización de middleware en el orden correcto no funcionará según lo previsto, dejando la aplicación expuesta a una variedad de problemas de seguridad.

Ejemplo 1: El método UseCookiePolicy() agrega el middleware de política de cookies a la canalización de middleware, lo que permite políticas de cookies personalizadas. Cuando se especifica en el orden incorrecto, como se muestra, se ignorará cualquier política de cookies establecida por el programador.

Abstract
La aplicación especifica incorrectamente el middleware de redirección HTTPS ASP.NET predeterminado.
Explanation
El middleware ASP.NET Core que no se agrega a la canalización de middleware en el orden correcto no funcionará según lo previsto, dejando la aplicación expuesta a una variedad de problemas de seguridad.

Ejemplo 1: El método UseHttpsRedirection() agrega middleware de redirección HTTPS a la canalización de middleware, lo que permite la redirección de solicitudes HTTP no seguras a una solicitud HTTPS segura. Cuando se especifica en el orden incorrecto, como se muestra, no se producirá una redirección HTTPS significativa antes de procesar la solicitud a través del middleware que se muestra antes de la redirección. Esto permitirá que la aplicación procese las solicitudes HTTP antes de redirigirlas a la conexión HTTPS segura.

Abstract
Deshabilitar la validación de certificados es extremadamente peligroso.
Explanation
Configurar el modo de validación del certificado en None desactiva todo el proceso de validación de la certificación, lo que expone la aplicación a ataques de tipo "man-in-the-middle". Este modo no debe utilizarse en entornos de producción.

Abstract
Los atacantes pueden ver o modificar el contenido de las cookies desprotegidas.
Explanation
Las cookies se utilizan a menudo para almacenar información importante sobre los usuarios, como información personal, tokens de autenticación y un historial de su actividad. Si esta información se almacena en texto sin formato, cualquier persona con acceso a las máquinas utilizadas para interactuar con la aplicación tendrá acceso a la información almacenada en la cookie. Peor aún, si pueden modificar arbitrariamente los datos almacenados en las cookies, los atacantes también pueden falsificar la información proporcionada a la aplicación y potencialmente alterar su comportamiento en su beneficio.

En muchos casos, una aplicación puede validar la entrada de las cookies mediante programación de acuerdo con el contexto en el que se utiliza, pero el marco de validación ASP.NET ofrece una manera excelente de proteger el contenido de la cookie y de verificar que la cookie no se haya modificado inesperadamente. Sin este método, es difícil, y a menudo imposible, establecer con un alto nivel de confianza que todas las entradas están validadas.

Abstract
Los mensajes de depuración ayudan a los atacantes a conocer el sistema y planificar una forma de ataque.
Explanation
Las aplicaciones ASP .NET se pueden configurar para producir binarios de depuración. Estos binarios proporcionan mensajes de depuración detallados y no deben usarse en entornos de producción. El atributo debug de la etiqueta <compilation> define si los binarios compilados deben incluir información de depuración.

El uso de binarios de depuración hace que una aplicación proporcione al usuario tanta información sobre sí misma como sea posible. Los binarios de depuración están diseñados para usarse en un entorno de desarrollo o prueba y pueden suponer un riesgo de seguridad si se implementan en producción. Los atacantes pueden valerse de información adicional que obtengan del resultado de seguimiento para planear ataques contra el marco de trabajo, la base de datos o cualquier otro recurso que la aplicación utilice.

Abstract
Deshabilitar la validación de eventos de ASP.NET puede permitir a los atacantes enviar solicitudes postback no autorizadas o maliciosas.
Explanation
La validación de eventos es una característica de seguridad de ASP.NET que valida los controles de eventos en las solicitudes postback para garantizar que los controles sean los mismos que cuando se representaron durante la carga inicial de la página. Cuando esta característica está deshabilitada, los atacantes pueden llevar a cabo ataques de falsificación de solicitud entre sitios con controles de eventos manipulados, lo que lleva a accesos no autorizados, ataques de Cross-Site Scripting, etc.

Ejemplo 1: La siguiente configuración de la aplicación web deshabilita la validación de eventos.

...
<system.web>
...
<pages enableEventValidation="false">
...
</pages>
</system.web>
Ejemplo 2: La siguiente directiva de página de servidor deshabilita la validación de eventos.

<%@ Page ... EnableEventValidation="false" %>

Abstract
Un tiempo de espera de autenticación demasiado largo les da a los atacantes más tiempo para comprometer potencialmente las cuentas de los usuarios.
Explanation
Cuanto más tiempo permanece abierta una sesión, mayor es la ventana de oportunidad que tiene un atacante para comprometer las cuentas de usuario. Mientras una sesión permanece activa, un atacante puede forzar la contraseña de un usuario, descifrar su clave de cifrado inalámbrica o controlar una sesión desde un explorador abierto. Los tiempos de espera de autenticación más prolongados también pueden evitar que se libere la memoria y acabar en una denegación de servicio si se crea una cantidad suficientemente grande de sesiones.

Ejemplo 1: El siguiente ejemplo muestra ASP.NET MVC configurado con un tiempo de espera de autenticación de una hora.

...
<configuration>
<system.web>
<authentication>
<forms
timeout="60" />
</authentication>
</system.web>
</configuration>
...


Si no se especifica el atributo de tiempo de espera, el tiempo de espera de autenticación predeterminado es de 30 minutos.

Abstract
Al deshabilitar la comprobación de encabezados se abre la puerta a los atacantes para que realicen ataques de manipulación de los encabezados.
Explanation
De forma predeterminada, .NET Framework impide el envío de nuevos caracteres a API que definen valores de encabezado HTTP. No obstante, este comportamiento se puede deshabilitar mediante programación configurando la propiedad EnableHeaderChecking en el objeto HttpRuntimeSection como false.

Ejemplo: el código siguiente deshabilita la comprobación de encabezados.

Configuration config = WebConfigurationManager.OpenWebConfiguration("/MyApp");
HttpRuntimeSection hrs = (HttpRuntimeSection) config.GetSection("system.web/httpRuntime");
hrs.EnableHeaderChecking = false;


Cuando se deshabilita esta comprobación, el código que permite las entradas de usuario para llegar a las API de configuración de encabezados es vulnerable a ataques como la división de respuesta de HTTP.
