Abstract
Si se permite que la entrada de usuario modifique directamente los permisos de archivo, un atacante podría acceder a los recursos del sistema protegidos de otra forma.
Explanation
Se producen errores File Permission Manipulation cuando se cumplen algunas de las siguientes condiciones:

1. Un atacante puede especificar una ruta de acceso utilizada en una operación que modifica los permisos del sistema de archivos.

2. Un atacante puede especificar los permisos asignados por una operación en el sistema de archivos.

Ejemplo 1: El siguiente código utiliza la entrada de las variables de entorno del sistema para establecer los permisos de archivo. Si los atacantes pueden modificar las variables de entorno del sistema, pueden utilizar el programa para obtener acceso a los archivos que el programa ha manipulado. Si el programa también es vulnerable a Path Manipulation, un atacante puede utilizar esta vulnerabilidad para obtener acceso a archivos arbitrarios del sistema.

Abstract
Si se permite que la entrada de usuario modifique directamente los permisos de archivo, un atacante puede acceder a los recursos del sistema protegidos de otra forma.
Explanation
Se producen errores de manipulación de permisos de archivo cuando se cumplen algunas de las siguientes condiciones:

1. Un atacante puede especificar una ruta de acceso utilizada en una operación que modifica los permisos del sistema de archivos.

2. Un atacante puede especificar los permisos asignados por una operación en el sistema de archivos.

Ejemplo: el siguiente código se ha diseñado para establecer los permisos de archivo adecuados para los usuarios que cargan las páginas web a través de FTP. Utiliza la entrada de una solicitud HTTP para marcar un archivo como visible para los usuarios externos.


$rName = $_GET['publicReport'];
chmod("/home/". authenticateUser . "/public_html/" . rName,"0755");
...


Sin embargo, si un usuario malintencionado proporciona un valor malicioso para publicReport como, por ejemplo, "../../localuser/public_html/.htpasswd", la aplicación hará que el archivo especificado sea legible para el usuario malintencionado.

Ejemplo 2: el siguiente código utiliza la entrada desde un archivo de configuración para establecer la máscara de permisos predeterminada. Si los usuarios malintencionados pueden modificar el archivo de configuración, pueden utilizar el programa para obtener acceso a los archivos que el programa ha manipulado. Si el programa también es vulnerable a la manipulación de rutas de acceso, un usuario malintencionado puede utilizar esta vulnerabilidad para obtener acceso a archivos arbitrarios del sistema.

Abstract
El programa define una directiva entre dominios demasiado permisiva.
Explanation
De forma predeterminada, las aplicaciones Flash están sujetas a la misma directiva de origen, lo que garantiza que dos aplicaciones SWF pueden tener acceso a los datos respectivos solo si proceden del mismo dominio. Adobe Flash permite a los desarrolladores modificar la directiva mediante programación o a través de la configuración adecuada en el archivo de configuración crossdomain.xml. Sin embargo, es necesario tener cuidado al cambiar la configuración porque una directiva entre dominios demasiado permisiva permitirá que una aplicación malintencionada se comunique con la aplicación víctima de manera inadecuada, lo que provocará suplantación de identidad, robo de datos, retransmisión y otros ataques.

Ejemplo 1: El código siguiente es un ejemplo del uso de un carácter comodín para especificar mediante programación los dominios con los que la aplicación se puede comunicar.


flash.system.Security.allowDomain("*");


El uso de * como el argumento de allowDomain() indica que otras aplicaciones SWF pueden tener acceso a los datos desde cualquier dominio.

Abstract
El programa define una directiva de encabezados personalizados demasiado permisiva.
Explanation
De forma predeterminada, las aplicaciones Flash están sujetas a la misma directiva de origen, lo que garantiza que dos aplicaciones SWF pueden tener acceso a los datos respectivos solo si proceden del mismo dominio. Adobe Flash permite a los desarrolladores modificar la directiva mediante programación o a través de la configuración adecuada en el archivo de configuración crossdomain.xml. A partir de Flash Player 9,0,124,0, Adobe también introdujo la capacidad de definir qué encabezados personalizados Flash Player puede enviar a través de dominios. Sin embargo, se debe tener precaución al definir esta configuración porque una directiva de encabezados personalizados demasiado permisiva, cuando se aplica junto con la directiva entre dominios demasiado permisiva, permitirá que una aplicación malintencionada envíe encabezados de su elección a la aplicación de destino, lo que podría conducir a diversos ataques o provocar errores en la ejecución de la aplicación que no sabe cómo manejar los encabezados recibidos.

Ejemplo 1: La configuración siguiente muestra el uso de un carácter comodín para especificar los encabezados que puede enviar Flash Player entre dominios.


<cross-domain-policy>
<allow-http-request-headers-from domain="*" headers="*"/>
</cross-domain-policy>


Utilizar el* como el valor del atributo headers indica que cualquier encabezado se enviará a través de dominios.

Abstract
El programa utiliza la entrada del usuario no validada para eludir las restricciones de directiva entre dominios.
Explanation
De forma predeterminada, las aplicaciones Flash están sujetas a la misma directiva de origen, lo que garantiza que dos aplicaciones SWF pueden tener acceso a los datos respectivos solo si proceden del mismo dominio. Adobe Flash permite a los desarrolladores modificar la directiva mediante programación o a través de la configuración adecuada en el archivo de configuración crossdomain.xml. Sin embargo, es necesario tener cuidado al decidir quién puede influir en la configuración porque una directiva entre dominios demasiado permisiva permitirá que una aplicación malintencionada se comunique con la aplicación víctima de manera inadecuada, lo que provocará suplantación de identidad, robo de datos, retransmisión y otros ataques. Las vulnerabilidades de omisión de las restricciones de directivas se producen cuando:

1. Los datos entran en una aplicación desde una fuente no confiable.

2. Los datos se utilizan para cargar o modificar la configuración de directivas entre dominios.
Ejemplo 1: El siguiente código utiliza el valor de uno de los parámetros para el archivo SWF cargado como la dirección URL desde donde cargar el archivo de directivas entre dominios.


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var url:String = String(params["url"]);
flash.system.Security.loadPolicyFile(url);
...
Ejemplo 2: El siguiente código utiliza el valor de uno de los parámetros para el archivo SWF cargado con el fin de definir la lista de dominios de confianza.


...
var params:Object = LoaderInfo(this.root.loaderInfo).parameters;
var domain:String = String(params["domain"]);
flash.system.Security.allowDomain(domain);

Abstract
El programa permite que las aplicaciones SWF de HTTP y HTTPS se comuniquen.
Explanation
A partir de Flash Player 7, no se permite que las aplicaciones SWF cargadas a través de HTTP tengan acceso a los datos de las aplicaciones SWF cargadas a través de HTTPS de forma predeterminada. Adobe Flash permite a los desarrolladores modificar esta restricción mediante programación o a través de la configuración adecuada en el archivo de configuración crossdomain.xml. Sin embargo, se deben tomar precauciones al definir esta configuración porque las aplicaciones SWF cargadas a través de HTTP son objeto de ataques Man-In-The-Middle (MITM) y, por tanto, no son de confianza.

Ejemplo: El siguiente código llama a allowInsecureDomain(), que desactiva la restricción que impide que las aplicaciones SWF cargadas a través de HTTP tengan acceso a los datos de las aplicaciones SWF cargadas a través de HTTPS.


flash.system.Security.allowInsecureDomain("*");

Abstract
La información de depuración ayuda a los atacantes a conocer el sistema y planificar una forma de ataque.
Explanation
Si está utilizando Blaze DS para llevar a cabo el registro de eventos inesperados, el archivo del descriptor services-config.xml especifica un elemento XML "Logging" (Registro) para describir los diferentes aspectos del registro. Tiene un formato similar al siguiente:

Ejemplo:

<logging>
<target class="flex.messaging.log.ConsoleTarget" level="Debug">
<properties>
<prefix>[BlazeDS]</prefix>
<includeDate>false</includeDate>
<includeTime>false</includeTime>
<includeLevel>false</includeLevel>
<includeCategory>false</includeCategory>
</properties>
<filters>
<pattern>Endpoint.*</pattern>
<pattern>Service.*</pattern>
<pattern>Configuration</pattern>
</filters>
</target>
</logging>


Esta etiqueta target toma un atributo opcional que se llama level, el cual indica el nivel de registro. Si el nivel de depuración se establece en un nivel demasiado detallado, su aplicación puede escribir datos confidenciales en el archivo de registro.

Abstract
La concatenación de entradas sin validar en una dirección URL puede permitir a un usuario malintencionado anular el valor de un parámetro de solicitud. El usuario malintencionado puede anular los valores de los parámetros existentes, inyectar un nuevo parámetro o atacar las variables fuera de un alcance directo.
Explanation
Los ataques HPP (HTTP Parameter Pollution) consisten en inyectar delimitadores de cadenas de consulta codificados en otros parámetros existentes. Si una aplicación web no corrige adecuadamente la entrada del usuario, un usuario malintencionado puede poner en peligro la lógica de la aplicación para llevar a cabo ataques del lado de cliente o del servidor. Mediante el envío de parámetros adicionales a una aplicación web y si estos parámetros tienen el mismo nombre que un parámetro existente, la aplicación web puede reaccionar de una de las siguientes maneras:

Solo puede obtener los datos del primer parámetro
Puede obtener los datos del último parámetro
Puede obtener los datos de todos los parámetros y concatenarlos juntos


Por ejemplo:
- ASP.NET/IIS utiliza todas las apariciones de los parámetros
- Apache Tomcat utiliza solo la primera aparición e ignora las demás.
- mod_perl/Apache convierte el valor en una matriz de valores

Ejemplo 1: según el servidor de aplicaciones y la lógica de la propia aplicación, la siguiente solicitud podría provocar confusión en el sistema de autenticación y permitir que un atacante suplante a otro usuario.
http://www.server.com/login.aspx?name=alice&name=hacker

Ejemplo 2: el siguiente código utiliza la entrada de una solicitud HTTP para representar dos hipervínculos.

...
String lang = Request.Form["lang"];
WebClient client = new WebClient();
client.BaseAddress = url;
NameValueCollection myQueryStringCollection = new NameValueCollection();
myQueryStringCollection.Add("q", lang);
client.QueryString = myQueryStringCollection;
Stream data = client.OpenRead(url);
...


URL: http://www.host.com/election.aspx?poll_id=4567
Link1: <a href="http://www.host.com/vote.aspx?poll_id=4567&lang=en">inglés<a>
Link2: <a href="http://www.host.com/vote.aspx?poll_id=4567&lang=es">español<a>

El programador no ha tenido en cuenta la posibilidad de que un atacante proporcione un lang como en&poll_id=1 y después pueda modificar el poll_id a su antojo.

Abstract
La concatenación de entradas sin validar en una dirección URL puede permitir a un usuario malintencionado anular el valor de un parámetro de solicitud. El usuario malintencionado puede anular los valores de los parámetros existentes, inyectar un nuevo parámetro o atacar las variables fuera de un alcance directo.
Explanation
Los ataques HPP (HTTP Parameter Pollution) consisten en inyectar delimitadores de cadenas de consulta codificados en otros parámetros existentes. Si una aplicación web no corrige adecuadamente la entrada del usuario, un usuario malintencionado puede poner en peligro la lógica de la aplicación para llevar a cabo ataques del lado de cliente o del servidor. Mediante el envío de parámetros adicionales a una aplicación web y si estos parámetros tienen el mismo nombre que un parámetro existente, la aplicación web puede reaccionar de una de las siguientes maneras:

Solo puede obtener los datos del primer parámetro
Puede obtener los datos del último parámetro
Puede obtener los datos de todos los parámetros y concatenarlos juntos


Por ejemplo:
- ASP.NET/IIS utiliza todas las apariciones de los parámetros
- Apache Tomcat utiliza solo la primera aparición e ignora las demás.
- mod_perl/Apache convierte el valor en una matriz de valores

Ejemplo 1: según el servidor de aplicaciones y la lógica de la propia aplicación, la siguiente solicitud podría provocar confusión en el sistema de autenticación y permitir que un usuario malintencionado suplante a otro usuario.
http://www.server.com/login.php?name=alice&name=hacker

Como se muestra aquí, el usuario malintencionado ya ha especificado name=alice, pero ha agregado un name=alice& adicional, y si se utiliza en un servidor que tome la primera repetición, podría suplantar a alice para obtener más información sobre su cuenta.

Abstract
La aplicación permite la instalación de extensiones de teclado de terceros.
Explanation
Se permite que las extensiones de teclado lean cada tecla que pulsa el usuario. Por lo general, los teclados de terceros se usan para facilitar la introducción de texto o para agregar emojis adicionales y pueden registrar lo que el usuario pulsa o incluso enviarlo a un servidor remoto para su procesamiento. Los teclados malintencionados también pueden distribuirse para actuar como un registrador de pulsaciones de teclas y leer todas las teclas pulsadas por el usuario para robar datos confidenciales como credenciales o números de tarjetas de crédito.

Abstract
Al permitir que la entrada del usuario controle los parámetros Intent, se podría permitir que un usuario malintencionado controlara el comportamiento de la actividad siguiente.
Explanation
Se produce un problema de manipulación de finalidad cuando se cumplen las dos condiciones siguientes:

1. Un atacante puede especificar la acción, el nombre de clase o el componente de una finalidad de Android.

Por ejemplo, un atacante puede especificar el nombre de clase o el componente para gestionar la finalidad.

2. Al especificar la acción, el nombre de clase o el componente, el usuario malintencionado adquiere una capacidad que de otro modo no estaría permitida.

Por ejemplo, el programa puede otorgar al usuario malintencionado la capacidad de transmitir información confidencial a un software de terceros en el dispositivo.

Ejemplo 1: el siguiente código utiliza un argumento leído de una solicitud HTTP para establecer el nombre de clase de una finalidad.


String arg = request.getParameter("arg");
...
Intent intent = new Intent();
...
intent.setClassName(arg);
ctx.startActivity(intent);
...

Abstract
Se ha detectado un Intent interno implícito. Los intents internos implícitos pueden exponer el sistema a ataques de tipo intermediario en componentes internos.
Explanation
Un Intent interno utiliza una acción personalizada definida por un componente interno. Los intents implícitos pueden facilitar la llamada de intenciones desde cualquier componente externo determinado sin conocimiento del componente específico. La combinación de ambos permite que una aplicación acceda a intenciones especificadas para un uso interno específico desde fuera del contexto de la aplicación deseada.

La capacidad de procesar un Intent desde una aplicación externa puede permitir una amplia variedad de explotaciones de intermediario que varían en gravedad. desde fuga de información y denegación de servicio hasta ejecución remota de código, dependiendo de la capacidad de acción interna especificada por el Intent.

Ejemplo 1: El siguiente código utiliza un Intent interno implícito.


...
val imp_internal_intent_action = Intent("INTERNAL_ACTION_HERE")
startActivity(imp_internal_intent_action)

Abstract
Se ha detectado un PendingIntent implícito. Los intents pendientes implícitos pueden dar lugar a deficiencias de seguridad como denegación de servicio, fuga de información privada y del sistema y escalada de privilegios.
Explanation
Los intents de Android se utilizan para vincular aplicaciones y componentes de aplicaciones proporcionando instrucciones sobre las acciones que realiza un componente determinado. Los intents pendientes se crean para entregar el Intent más adelante. Los intents implícitos facilitan la llamada de intents desde cualquier componente externo determinado, utilizando un nombre general y un filtro para determinar la ejecución.

Cuando se crea un Intent implícito como PendingIntent, esto podría permitir que el Intent se envíe a un componente no deseado que se ejecuta fuera del contexto temporal previsto, dejando al sistema vulnerable para explotar vectores como la denegación de servicio, la fuga de información privada y del sistema y la escalada de privilegios.

Ejemplo 1: El código siguiente utiliza un PendingIntent implícito.


...
val imp_intent = Intent()
val flag_mut = PendingIntent.FLAG_MUTABLE
val pi_flagmutable_impintintent = PendingIntent.getService(
this,
0,
imp_intent,
flag_mut
)

Los intents pendientes creados con el valor de marca FLAG_MUTABLE son susceptibles de tener campos Intent no especificados configurados en sentido descendente, que pueden modificar la capacidad del Intent y dejar el sistema expuesto a deficiencias.
Explanation
Permitir la modificación del Intent subyacente de un PendingIntent después de su creación puede dejar un sistema abierto a ataques. Esto depende principalmente de la capacidad general del Intent subyacente. En la mayoría de los casos, se recomienda evitar posibles problemas configurando la marca PendingIntent en FLAG_IMMUTABLE.

Ejemplo 1: El siguiente incluye un PendingIntent creado con un valor de marca de FLAG_MUTABLE.


...
val intent_flag_mut = Intent(Intent.ACTION_GTALK_SERVICE_DISCONNECTED, Uri.EMPTY, this, DownloadService::class.java)
val flag_mut = PendingIntent.FLAG_MUTABLE

val pi_flagmutable = PendingIntent.getService(
this,
0,
intent_flag_mut,
flag_mut
)
...

Abstract
El uso de un Intent anidado de una entrada externa para iniciar una actividad, iniciar un servicio o entregar una transmisión puede permitir que un atacante lance arbitrariamente componentes internos de la aplicación, controle el comportamiento de un componente interno o acceda indirectamente a datos protegidos de un proveedor de contenido a través de concesiones de permisos.
Explanation
Se produce un problema manipulación de intento de redireccionamiento cuando se cumplen las condiciones siguientes:
1. Un componente exportado acepta un Intent arbitrario anidado en el paquete de extras de un Intent proporcionado externamente.

2. El componente exportado utiliza el Intent arbitrario para iniciar un componente llamando a startActivity, startService o sendBroadcast.

Un atacante posiblemente pueda obtener una capacidad que de otro modo no estaría permitida cuando existen estas condiciones.
Ejemplo 1: El siguiente código acepta un Intent anidado de una fuente externa y usa ese Intent para iniciar una actividad.


...
Intent nextIntent = (Intent) getIntent().getParcelableExtra("next-intent");
startActivity(nextIntent);
...

Abstract
Las claves de cifrado vacías pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
El uso de una clave de cifrado vacía nunca es una buena idea porque reduce considerablemente la protección que proporciona un buen algoritmo de cifrado y también dificulta en gran manera la solución del problema. Una vez que el código dañino está en ejecución, la clave de cifrado vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por la clave de cifrado vacía se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente utiliza una clave de cifrado vacía:


...
encryptionKey = "".
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado vacía, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que la aplicación se haya distribuido, se requiere una revisión del software para cambiar la clave de cifrado vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado vacía.

Abstract
Las claves de cifrado vacías pueden comprometer la seguridad una forma difícil de resolver.
Explanation
Nunca es una buena idea utilizar una clave de cifrado vacía. El uso de una clave de cifrado vacía no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en ejecución, la clave de cifrado vacía no se puede cambiar sin aplicar revisiones al software. Si una cuenta protegida por la clave de cifrado vacía se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo: El código siguiente utiliza una clave de cifrado vacía:


...
char encryptionKey[] = "";
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado vacía, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado vacía.

Las claves de cifrado vacías pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
El uso de una clave de cifrado vacía nunca es una buena idea porque reduce considerablemente la protección que proporciona un buen algoritmo de cifrado y también dificulta en gran manera la solución del problema. Una vez que el código dañino está en ejecución, la clave de cifrado vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por la clave de cifrado vacía se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente realiza el cifrado AES con una clave de cifrado vacía:


...
private static String encryptionKey = "";
byte[] keyBytes = encryptionKey.getBytes();
SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");
Cipher encryptCipher = Cipher.getInstance("AES");
encryptCipher.init(Cipher.ENCRYPT_MODE, key);
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado vacía, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que la aplicación se haya distribuido, se requiere una revisión del software para cambiar la clave de cifrado vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado vacía.

Abstract
Las claves de cifrado vacías pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
El uso de una clave de cifrado vacía nunca es una buena idea porque reduce considerablemente la protección que proporciona un buen algoritmo de cifrado y también dificulta en gran manera la solución del problema. Una vez que el código dañino está en ejecución, la clave de cifrado vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por la clave de cifrado vacía se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Nunca es una buena idea utilizar una clave de cifrado vacía. El uso de una clave de cifrado vacía no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en ejecución, la clave de cifrado vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por la clave de cifrado vacía se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El código siguiente utiliza una función de derivación de claves basadas en contraseñas con una longitud de clave de cero, lo que produce una clave de cifrado vacía:


require 'openssl'
...
dk = OpenSSL::PKCS5::pbkdf2_hmac_sha1(password, salt, 100000, 0) # returns an empty string
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado vacía, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado vacía.

Abstract
Las claves de cifrado vacías pueden comprometer la seguridad una forma difícil de resolver.
Explanation
Nunca es una buena idea utilizar una clave de cifrado vacía. El uso de una clave de cifrado vacía no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en ejecución, la clave de cifrado vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por la clave de cifrado vacía se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente realiza el cifrado AES con una clave de cifrado vacía:


...
CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmAES128),
UInt32(kCCOptionPKCS7Padding),
"",
0,
iv,
plaintext,
plaintext.length,
ciphertext.mutableBytes,
ciphertext.length,
&numBytesEncrypted)
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado vacía, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado vacía. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado vacía.

Abstract
Las claves HMAC vacías podrían comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea utilizar una clave HMAC vacía. La intensidad criptográfica de HMAC depende del tamaño de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. El uso de una clave vacía debilita la intensidad criptográfica de la función HMAC.
Ejemplo 1: El siguiente código utiliza una clave vacía para el cálculo de HMAC:

...
DATA: lo_hmac TYPE Ref To cl_abap_hmac,
Input_string type string.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_algorithm = 'SHA3'
if_key = space
RECEIVING
ro_object = lo_hmac.

" update HMAC with input
lo_hmac->update( if_data = input_string ).

" finalise hmac
lo_digest->final( ).

...


Puede ser que el código mostrado en el Example 1 se ejecute correctamente, pero cualquiera con acceso a él puede darse cuenta de que utiliza una clave HMAC vacía. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC vacía, a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC. Además, el código en el Example 1 es vulnerable a las falsificaciones y a los ataques de recuperación de claves.

desc.structural.abap.key_management_empty_hmac_key
Abstract
Las claves HMAC vacías podrían comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea utilizar una clave HMAC vacía. La intensidad criptográfica de HMAC depende del tamaño de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. El uso de una clave vacía debilita la intensidad criptográfica de la función HMAC.
Ejemplo 1: El siguiente código utiliza una clave vacía para el cálculo de HMAC:

...
using (HMAC hmac = HMAC.Create("HMACSHA512"))
{
string hmacKey = "";
byte[] keyBytes = Encoding.ASCII.GetBytes(hmacKey);
hmac.Key = keyBytes;
...
}
...


Puede ser que el código del Example 1 se ejecute correctamente, pero cualquiera con acceso a él puede darse cuenta de que utiliza una clave HMAC vacía. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC vacía, a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC. Además, el código en el Example 1 es vulnerable a las falsificaciones y a los ataques de recuperación de claves.

Abstract
Las claves HMAC vacías podrían comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea utilizar una clave HMAC vacía. La intensidad criptográfica de HMAC depende del tamaño de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. El uso de una clave vacía debilita la intensidad criptográfica de la función HMAC.

Ejemplo 1: El siguiente código utiliza una clave vacía para el cálculo de HMAC:


...
CCHmac(kCCHmacAlgSHA256, "", 0, plaintext, plaintextLen, &output);
...


Puede ser que el código del Example 1 se ejecute correctamente, pero cualquiera con acceso a él puede darse cuenta de que utiliza una clave HMAC vacía. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC vacía, a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC. Además, el código en el Example 1 es vulnerable a las falsificaciones y a los ataques de recuperación de claves.

Abstract
Las claves HMAC vacías podrían comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea utilizar una clave HMAC vacía. La intensidad criptográfica de HMAC depende del tamaño de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. El uso de una clave vacía debilita la intensidad criptográfica de la función HMAC.

Ejemplo 1: El siguiente código utiliza una clave vacía para el cálculo de HMAC:


...
CCHmac(UInt32(kCCHmacAlgSHA256), "", 0, plaintext, plaintextLen, &output)
...


Puede ser que el código del Example 1 se ejecute correctamente, pero cualquiera con acceso a él puede darse cuenta de que utiliza una clave HMAC vacía. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC vacía, a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC. Además, el código en el Example 1 es vulnerable a las falsificaciones y a los ataques de recuperación de claves.

Abstract
El uso de una clave generada por una función de derivación de claves basada en contraseña a la que se pasó un valor vacío para su argumento de contraseña podría comprometer la seguridad del sistema de una forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea pasar un valor vacío como argumento de contraseña a una función de derivación de claves basada en contraseñas criptográfica (PBKDF). En este caso, la clave derivada se basará exclusivamente en la sal proporcionada (debilitándola considerablemente) y complicará en gran medida la solución del problema. Una vez que el código dañino está en ejecución, a menudo la contraseña vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por una clave derivada basada en una contraseña vacía se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa la cadena vacía como el argumento de contraseña a una PBKDF criptográfica:


...
Rfc2898DeriveBytes rdb = new Rfc2898DeriveBytes("", salt,100000);
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña vacía, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso al valor de sal que se usa para generar cualquiera de las claves basadas en una contraseña vacía, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña vacía, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña vacía.

Abstract
Se utiliza una contraseña vacía para generar una clave a partir de una función de derivación de claves basada en contraseñas (PBKDF). El establecimiento de contraseñas vacías a una PBKDF compromete la seguridad del sistema de una forma difícil de resolver.
Explanation
Nunca es una buena idea pasar un valor vacío como argumento de contraseña a una función de derivación de claves basada en contraseñas criptográfica (PBKDF). En este caso, la clave derivada se basará exclusivamente en la sal proporcionada (debilitándola considerablemente) y complicará en gran medida la solución del problema. Una vez que el código dañino está en ejecución, a menudo la contraseña vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por una clave derivada basada en una contraseña vacía se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa la cadena vacía como el argumento de contraseña a una PBKDF criptográfica:


...
CCKeyDerivationPBKDF(kCCPBKDF2,
"",
0,
salt,
saltLen
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña vacía, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso al valor de sal que se usa para generar cualquiera de las claves basadas en una contraseña vacía, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña vacía, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña vacía.

Ejemplo 2: Algunas API de nivel inferior pueden requerir pasar la longitud de determinados argumentos, además de los valores de los argumentos, de manera que una función pueda leer el valor del argumento como un número de bytes consecutivos, empezando por la ubicación del argumento en la memoria. El siguiente código pasa a cero como el argumento de longitud de contraseña a una PBKDF criptográfica:


...
CCKeyDerivationPBKDF(kCCPBKDF2,
password,
0,
salt,
saltLen
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...


En este caso, incluso si password contiene un valor de contraseña seguro y administrado adecuadamente, al pasar su longitud como cero se obtendrá un valor de contraseña vacío, null o con alguna otra debilidad inesperada.

Abstract
Se utiliza una contraseña vacía para generar una clave a partir de una función de derivación de claves basada en contraseñas (PBKDF). El establecimiento de contraseñas vacías a una PBKDF compromete la seguridad del sistema de una forma difícil de resolver.
Explanation
Nunca es una buena idea pasar un valor vacío como argumento de contraseña a una función de derivación de claves basada en contraseñas criptográfica (PBKDF). En este caso, la clave derivada se basará exclusivamente en la sal proporcionada (debilitándola considerablemente) y complicará en gran medida la solución del problema. Una vez que el código dañino está en ejecución, a menudo la contraseña vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por una clave derivada basada en una contraseña vacía se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa la cadena vacía como el argumento de contraseña a una PBKDF criptográfica:


...
key = OpenSSL::PKCS5::pbkdf2_hmac('', salt, 100000, 256, 'SHA256')
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña vacía, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso al valor de sal que se usa para generar cualquiera de las claves basadas en una contraseña vacía, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña vacía, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña vacía.

Si la cuenta protegida por una clave derivada basada en una contraseña vacía se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa la cadena vacía como el argumento de contraseña a una PBKDF criptográfica:


...
CCKeyDerivationPBKDF(CCPBKDFAlgorithm(kCCPBKDF2),
"",
0,
salt,
saltLen,
CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256),
100000,
derivedKey,
derivedKeyLen)
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña vacía, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso al valor de sal que se usa para generar cualquiera de las claves basadas en una contraseña vacía, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña vacía, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña vacía.

Ejemplo 2: Algunas API de nivel inferior pueden requerir pasar la longitud de determinados argumentos, además de los valores de los argumentos, de manera que una función pueda leer el valor del argumento como un número de bytes consecutivos, empezando por la ubicación del argumento en la memoria. El siguiente código pasa a cero como el argumento de longitud de contraseña a una PBKDF criptográfica:


...
CCKeyDerivationPBKDF(CCPBKDFAlgorithm(kCCPBKDF2),
password,
0,
salt,
saltLen,
CCPseudoRandomAlgorithm(kCCPRFHmacAlgSHA256),
100000,
derivedKey,
derivedKeyLen)
...


En este caso, incluso si password contiene un valor de contraseña seguro y administrado adecuadamente, al pasar su longitud como cero se obtendrá un valor de contraseña vacío, null o con alguna otra debilidad inesperada.

Abstract
Las claves de cifrado con codificación rígida pueden poner en riesgo la seguridad de una forma que no es fácil resolver.
Explanation
La codificación rígida de una clave de cifrado nunca es una buena idea porque permite que todos los desarrolladores del proyecto puedan ver la clave de cifrado y dificulta en gran manera la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente utiliza una clave de cifrado codificada de forma rígida:


...
encryptionKey = "lakdsljkalkjlksdfkl".
...


Cualquiera que tenga acceso al código, tendrá acceso también a la clave de cifrado. Una vez que se ha enviado la aplicación, no hay forma de cambiar la clave de cifrado, a menos que se aplique una revisión al programa. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación podrían extraer el valor de la clave de cifrado.

Abstract
Las claves de cifrado con codificación rígida pueden poner en riesgo la seguridad de una forma que no es fácil resolver.
Explanation
La codificación rígida de una clave de cifrado nunca es una buena idea porque permite que todos los desarrolladores del proyecto puedan ver la clave de cifrado y dificulta en gran manera la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente utiliza una clave de cifrado codificada de forma rígida:


...
var encryptionKey:String = "lakdsljkalkjlksdfkl";
var key:ByteArray = Hex.toArray(Hex.fromString(encryptionKey));
...
var aes.ICipher = Crypto.getCipher("aes-cbc", key, padding);
...


Cualquiera que tenga acceso al código, tendrá acceso también a la clave de cifrado. Una vez que se ha enviado la aplicación, no hay forma de cambiar la clave de cifrado, a menos que se aplique una revisión al programa. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación podrían extraer el valor de la clave de cifrado.

Abstract
Las claves de cifrado con codificación rígida pueden poner en riesgo la seguridad de una forma que no es fácil resolver.
Explanation
Nunca codifique una clave de cifrado porque hace que la clave de cifrado sea visible para todos los desarrolladores del proyecto y que solucionar el problema sea extremadamente difícil. Para cambiar la clave de cifrado después de que el código esté en producción se necesita una revisión de software. Si la cuenta que protege la clave de cifrado se ve comprometida, el propietario del sistema debe elegir entre seguridad y disponibilidad.

Ejemplo 1: El código siguiente realiza el cifrado AES con una clave de cifrado codificada de forma rígida:


...
Blob encKey = Blob.valueOf('YELLOW_SUBMARINE');
Blob encrypted = Crypto.encrypt('AES128', encKey, iv, input);
...


Cualquiera que tenga acceso al código puede ver la clave de cifrado. Una vez distribuida la aplicación, no hay forma de cambiar la clave de cifrado sin una revisión de software. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Cualquier atacante con acceso al ejecutable de la aplicación puede extraer el valor de la clave de cifrado.

Abstract
Las claves de cifrado con codificación rígida pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea aplicar codificación rígida a una clave de cifrado. La codificación rígida de una clave de cifrado no solo permite que todos los desarrolladores de proyectos vean la clave de cifrado, sino que además dificulta la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo: el código siguiente utiliza una clave de cifrado codificada de forma rígida:


...
char encryptionKey[] = "lakdsljkalkjlksdfkl";
...


Cualquiera que tenga acceso al código, tendrá acceso también a la clave de cifrado. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave de cifrado a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían desensamblar el código, donde se encuentra el valor de la clave de cifrado utilizada.

Abstract
Las claves de cifrado con codificación rígida pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
La codificación rígida de una clave de cifrado nunca es una buena idea porque permite que todos los desarrolladores del proyecto puedan ver la clave de cifrado y dificulta en gran manera la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente utiliza una clave de cifrado codificada de forma rígida:


...
private static final String encryptionKey = "lakdsljkalkjlksdfkl";
byte[] keyBytes = encryptionKey.getBytes();
SecretKeySpec key = new SecretKeySpec(keyBytes, "AES");
Cipher encryptCipher = Cipher.getInstance("AES");
encryptCipher.init(Cipher.ENCRYPT_MODE, key);
...


Cualquiera que tenga acceso al código, tendrá acceso también a la clave de cifrado. Una vez que se ha enviado la aplicación, no hay forma de cambiar la clave de cifrado, a menos que se aplique una revisión al programa. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación podrían extraer el valor de la clave de cifrado.

Abstract
Las contraseñas codificadas pueden poner en riesgo la seguridad del sistema de una forma que es difícil resolver.
Explanation
Nunca codifique de forma rígida contraseñas. No solo expone la contraseña a todos los desarrolladores del proyecto, sino que también hace que sea extremadamente difícil solucionar el problema. Una vez que el código está en fase de producción, seguramente se requiera una revisión del programa para cambiar la contraseña. Si la cuenta protegida por la contraseña se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.
Ejemplo: El JSON siguiente utiliza una contraseña con codificación rígida:


...
{
"username":"scott"
"password":"tiger"
}
...


Esta configuración puede ser válida, pero cualquiera que tenga acceso a la configuración lo tendrá también a la contraseña. Una vez que se ha lanzado el programa, cambiar la cuenta de usuario por defecto "scott" con una contraseña "tiger" es difícil. Cualquier persona con acceso a esta información podría utilizarla para irrumpir en el sistema.

desc.structural.objc.key_management_hardcoded_encryption_key
Abstract
Las claves de cifrado codificadas podrían comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea aplicar codificación rígida a una clave de cifrado. La codificación rígida de una clave de cifrado no solo permite que todos los desarrolladores de proyectos vean la clave de cifrado, sino que además dificulta la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.
Ejemplo: el siguiente código utiliza una clave de cifrado codificada para cifrar la información:


...
$encryption_key = 'hardcoded_encryption_key';

//$filter = new Zend_Filter_Encrypt('hardcoded_encryption_key');
$filter = new Zend_Filter_Encrypt($encryption_key);

$filter->setVector('myIV');

$encrypted = $filter->filter('text_to_be_encrypted');
print $encrypted;
...


Este código se ejecutará correctamente, pero cualquier usuario que tenga acceso al mismo tendrá acceso a la clave de cifrado. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave de cifrado codificada ('hardcoded_encryption_key'), a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer los datos cifrados por el sistema.

Abstract
Las claves de cifrado codificadas podrían comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea aplicar codificación rígida a una clave de cifrado. La codificación rígida de una clave de cifrado no solo permite que todos los desarrolladores de proyectos vean la clave de cifrado, sino que además dificulta la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.
Ejemplo 1: el código siguiente utiliza una clave de cifrado codificada de forma rígida:


require 'openssl'
...
encryption_key = 'hardcoded_encryption_key'
...
cipher = OpenSSL::Cipher::AES.new(256, 'GCM')
cipher.encrypt
...
cipher.key=encryption_key
...


Este código se ejecutará correctamente, pero cualquier usuario que tenga acceso al mismo tendrá acceso a la clave de cifrado. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave de cifrado codificada "hardcoded_encryption_key", a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer los datos cifrados por el sistema.

Abstract
Las claves de cifrado con codificación rígida pueden poner en riesgo la seguridad de una forma que no es fácil resolver.
Explanation
Nunca codifique una clave de cifrado porque hace que la clave de cifrado sea visible para todos los desarrolladores del proyecto y que solucionar el problema sea extremadamente difícil. Para cambiar la clave de cifrado después de que el código esté en producción se necesita una revisión de software. Si la cuenta que protege la clave de cifrado se ve comprometida, el propietario del sistema debe elegir entre seguridad y disponibilidad.

Ejemplo 1: El siguiente ejemplo muestra una clave de cifrado dentro de un archivo .pem:


...
-----BEGIN RSA PRIVATE KEY-----
MIICXwIBAAKBgQCtVacMo+w+TFOm0p8MlBWvwXtVRpF28V+o0RNPx5x/1TJTlKEl
...
DiJPJY2LNBQ7jS685mb6650JdvH8uQl6oeJ/aUmq63o2zOw=
-----END RSA PRIVATE KEY-----
...


Cualquiera que tenga acceso al código puede ver la clave de cifrado. Una vez distribuida la aplicación, no hay forma de cambiar la clave de cifrado a menos que se aplique una revisión al programa. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Cualquier atacante con acceso al ejecutable de la aplicación puede extraer el valor de la clave de cifrado.

Abstract
Las claves de cifrado con codificación rígida pueden poner en riesgo la seguridad de una forma que no es fácil resolver.
Explanation
La codificación rígida de una clave de cifrado nunca es una buena idea porque permite que todos los desarrolladores del proyecto puedan ver la clave de cifrado y dificulta en gran manera la solución del problema. Una vez que el código está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado. Si la cuenta protegida por la clave de cifrado se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: el código siguiente utiliza una clave de cifrado codificada de forma rígida:


...
Dim encryptionKey As String
Set encryptionKey = "lakdsljkalkjlksdfkl"
Dim AES As New System.Security.Cryptography.RijndaelManaged
On Error GoTo ErrorHandler
AES.Key = System.Text.Encoding.ASCII.GetBytes(encryptionKey)
...
Exit Sub
...


Cualquiera que tenga acceso al código, tendrá acceso también a la clave de cifrado. Una vez que se ha enviado la aplicación, no hay forma de cambiar la clave de cifrado, a menos que se aplique una revisión al programa. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación podrían extraer el valor de la clave de cifrado.

Abstract
Las claves HMAC codificadas de forma rígida podrían comprometer la seguridad del sistema de una forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea codificar una clave HMAC. La intensidad criptográfica de HMAC depende de la confidencialidad de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. La codificación de una clave HMAC permite que cualquiera con acceso al código fuente pueda verlo y debilita la intensidad criptográfica de la función.
Ejemplo: el siguiente código utiliza una clave codificada para el cálculo de HMAC:

...
DATA: lo_hmac TYPE Ref To cl_abap_hmac,
Input_string type string.

CALL METHOD cl_abap_hmac=>get_instance
EXPORTING
if_algorithm = 'SHA3'
if_key = 'secret_key'
RECEIVING
ro_object = lo_hmac.

" update HMAC with input
lo_hmac->update( if_data = input_string ).

" finalise hmac
lo_digest->final( ).

...


Este código se ejecutará correctamente, pero cualquier usuario con acceso al mismo tendrá acceso a la clave HMAC. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC codificada "secret_key", a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC.

Abstract
Las claves HMAC codificadas de forma rígida podrían comprometer la seguridad del sistema de una forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea codificar una clave HMAC. La intensidad criptográfica de HMAC depende de la confidencialidad de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. La codificación de una clave HMAC permite que cualquiera con acceso al código fuente pueda verlo y debilita la intensidad criptográfica de la función.
Ejemplo: El siguiente código utiliza una clave codificada para el cálculo de HMAC:

...
using (HMAC hmac = HMAC.Create("HMACSHA512"))
{
string hmacKey = "lakdsljkalkjlksdfkl";
byte[] keyBytes = Encoding.ASCII.GetBytes(hmacKey);
hmac.Key = keyBytes;
...
}


Este código se ejecutará correctamente, pero cualquier usuario con acceso al mismo tendrá acceso a la clave HMAC. Una vez lanzado el programa, no hay forma de cambiar la clave HMAC codificada "hmacKey", a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC.

Abstract
Las claves HMAC codificadas de forma rígida pueden comprometer la seguridad del sistema de una forma que no pueda resolverse fácilmente.
Explanation
Nunca codifique de forma rígida una clave HMAC. La intensidad criptográfica de HMAC depende de la confidencialidad de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. La codificación de forma rígida de una clave HMAC permite que cualquier persona con acceso al origen pueda verlo y debilita la intensidad criptográfica de la función.

Ejemplo 1: El siguiente código utiliza una clave codificada de forma rígida para el cálculo de HMAC:


import "crypto/hmac"
...
hmac.New(sha256.New, []byte("secret"))
...


Este código se ejecuta correctamente, pero cualquier persona con acceso a él tiene acceso a la clave HMAC. Una vez distribuido el programa, no hay forma de cambiar la clave HMAC “secret” codificada de forma rígida, a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC.

Abstract
Las claves HMAC codificadas de forma rígida podrían comprometer la seguridad del sistema de una forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea codificar una clave HMAC. La intensidad criptográfica de HMAC depende de la confidencialidad de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. La codificación de una clave HMAC permite que cualquiera con acceso al código fuente pueda verlo y debilita la intensidad criptográfica de la función.

Ejemplo: el siguiente código utiliza una clave codificada para el cálculo de HMAC:


...
CCHmac(kCCHmacAlgSHA256, "secret", 6, plaintext, plaintextLen, &output);
...


Este código se ejecutará correctamente, pero cualquier usuario con acceso al mismo tendrá acceso a la clave HMAC. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC codificada "secret", a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC.

Abstract
Las claves HMAC codificadas de forma rígida podrían comprometer la seguridad del sistema de una forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea codificar una clave HMAC. La intensidad criptográfica de HMAC depende de la confidencialidad de la clave secreta, que se utiliza para calcular y verificar los valores de autenticación de mensajes. La codificación de una clave HMAC permite que cualquiera con acceso al código fuente pueda verlo y debilita la intensidad criptográfica de la función.

Ejemplo: El siguiente código utiliza una clave codificada para el cálculo de HMAC:


...
CCHmac(UInt32(kCCHmacAlgSHA256), "secret", 6, plaintext, plaintextLen, &output)
...


Este código se ejecutará correctamente, pero cualquier usuario con acceso al mismo tendrá acceso a la clave HMAC. Una vez que se haya distribuido el programa, no hay forma de cambiar la clave HMAC codificada "secret", a menos que el programa tenga instaladas las revisiones. Un empleado malintencionado con acceso a esta información puede utilizarla para comprometer la función HMAC.

Abstract
Se utiliza una contraseña codificada para generar una clave a partir de una función de derivación de claves basada en contraseñas (PBKDF). El establecimiento de una contraseña con codificación rígida a una PBKDF compromete la seguridad del sistema de forma difícil de resolver.
Explanation
Nunca es una buena idea pasar un valor vacío como argumento de contraseña a una función de derivación de claves basada en contraseñas criptográfica (PBKDF). En este caso, la clave derivada se basará exclusivamente en la sal proporcionada (debilitándola considerablemente) y complicará en gran medida la solución del problema. Una vez que el código dañino está en ejecución, a menudo la contraseña vacía no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por una clave derivada basada en una contraseña vacía se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa un valor codificado como el argumento de contraseña a una PBKDF criptográfica:


...
Rfc2898DeriveBytes rdb = new Rfc2898DeriveBytes("password", salt,100000);
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña codificada, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso a la sal que se usa para generar cualquiera de las claves basadas en una contraseña codificada, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña codificada, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña codificada.

Abstract
La generación y el uso de una clave criptográfica basada en una contraseña codificada puede comprometer la seguridad del sistema de forma que no pueda resolverse fácilmente.
Explanation
Nunca pase un valor codificado como el argumento de contraseña a una función de derivación de clave basada en contraseña criptográfica (PBKDF). En este caso, la clave derivada se basa sobre todo en la sal proporcionada (debilitándola considerablemente) y complicará en gran medida la solución del problema. Una vez que el código dañino está en ejecución, normalmente la contraseña codificada no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por una clave derivada basada en una contraseña codificada se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa un valor codificado como el argumento de contraseña a una PBKDF criptográfica:


...
CCKeyDerivationPBKDF(kCCPBKDF2,
"secret",
6,
salt,
saltLen
kCCPRFHmacAlgSHA256,
100000,
derivedKey,
derivedKeyLen);
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña codificada, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso a la sal que se usa para generar cualquiera de las claves basadas en una contraseña codificada, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña codificada, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña codificada.

Abstract
Se utiliza una contraseña codificada para generar una clave a partir de una función de derivación de claves basada en contraseñas (PBKDF). El establecimiento de una contraseña con codificación rígida a una PBKDF compromete la seguridad del sistema de forma difícil de resolver.
Explanation
Nunca pase un valor codificado como el argumento de contraseña a una función de derivación de clave basada en contraseña criptográfica (PBKDF). En este caso, la clave derivada se basa sobre todo en la sal proporcionada (debilitándola considerablemente) y complicará en gran medida la solución del problema. Una vez que el código dañino está en ejecución, normalmente la contraseña codificada no se puede cambiar sin aplicar revisiones al software. Si la cuenta protegida por una clave derivada basada en una contraseña codificada se ve comprometida, los propietarios del sistema podrían verse obligados a elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El siguiente código pasa un valor codificado como el argumento de contraseña a una PBKDF criptográfica:


...
key = OpenSSL::PKCS5::pbkdf2_hmac('password', salt, 100000, 256, 'SHA256')
...


No solo permitirá a cualquiera con acceso al código determinar que genere una o varias claves criptográficas basadas en un argumento de contraseña codificada, sino que cualquier usuario malintencionado podrá obtener acceso a cualquier recurso protegido por las claves dañinas. Si, además, un usuario malintencionado tiene acceso a la sal que se usa para generar cualquiera de las claves basadas en una contraseña codificada, le resultará muy sencillo descifrar esas claves. Una vez lanzado el programa, no hay forma de cambiar la contraseña codificada, a menos que el programa tenga instaladas las revisiones. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Incluso si los usuarios malintencionados tuvieran solo acceso al ejecutable de la aplicación, podrían saber que se está usando una contraseña codificada.

Abstract
Las claves de cifrado Null pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
El uso de una clave de cifrado null nunca es una buena idea porque reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, pero también dificulta en gran medida la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El código siguiente realiza el cifrado AES con una clave de cifrado null:


...
var encryptionKey:ByteArray = null;
...
var aes.ICipher = Crypto.getCipher("aes-cbc", encryptionKey, padding);
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado null, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez lanzada la aplicación, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

Abstract
Las claves de cifrado Null pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea utilizar una clave de cifrado null. El uso de una clave de cifrado null no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo: El código siguiente utiliza una clave de cifrado null:


...
char encryptionKey[] = null;
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado null, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

Cualquier usuario con acceso al código puede determinar si se utiliza una clave de cifrado null. Además, un usuario que aplique técnicas de descifrado básicas tiene muchas más probabilidades de descifrar con éxito los datos cifrados. Una vez distribuida la aplicación, se requiere una revisión de software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

desc.semantic.java.key_management_null_encryption_key
Abstract
Las claves de cifrado nulas pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
El uso de una clave de cifrado null nunca es una buena idea porque reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, pero también dificulta en gran medida la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El código siguiente realiza el cifrado AES con una clave de cifrado null:


...
var crypto = require('crypto');
var encryptionKey = null;
var algorithm = 'aes-256-ctr';
var cipher = crypto.createCipher(algorithm, encryptionKey);
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado null, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez lanzada la aplicación, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

Abstract
Las claves de cifrado nulas pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
Asignar null a las variables de la clave de cifrado no es una buena idea, ya que puede permitir a los usuarios malintencionados mostrar información confidencial y cifrada. El uso de una clave de cifrado null no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo: El siguiente código inicia una variable de clave de cifrado como null.


...
$encryption_key = NULL;

$filter = new Zend_Filter_Encrypt($encryption_key);

$filter->setVector('myIV');

$encrypted = $filter->filter('text_to_be_encrypted');
print $encrypted;
...

Cualquier persona que tenga acceso al código podría determinar que este utiliza una clave de cifrado null, y cualquier persona que aplique técnicas de descifrado, incluso básicas, tiene muchas probabilidades de descifrar correctamente los datos cifrados. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

Abstract
Las claves de cifrado nulas pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
El uso de una clave de cifrado null nunca es una buena idea porque reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, pero también dificulta en gran medida la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.



No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado null, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez lanzada la aplicación, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

Abstract
Las claves de cifrado nulas pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
Asignar None a las variables de la clave de cifrado no es una buena idea, ya que puede permitir a los usuarios malintencionados mostrar información confidencial y cifrada. El uso de una clave de cifrado null no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo: El siguiente código inicia una variable de clave de cifrado como null.

...
from Crypto.Ciphers import AES
cipher = AES.new(None, AES.MODE_CFB, iv)
msg = iv + cipher.encrypt(b'Attack at dawn')
...


Cualquier persona que tenga acceso al código podría determinar que este utiliza una clave de cifrado null, y cualquier persona que aplique técnicas de descifrado, incluso básicas, tiene muchas probabilidades de descifrar correctamente los datos cifrados. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.

Abstract
Las claves de cifrado Null pueden comprometer la seguridad de forma que no pueda resolverse fácilmente.
Explanation
Nunca es una buena idea utilizar una clave de cifrado null. El uso de una clave de cifrado null no solo reduce considerablemente la protección que proporciona un buen algoritmo de cifrado, sino que además dificulta enormemente la solución del problema. Una vez que el código dañino está en fase de producción, se requiere una revisión del software para cambiar la clave de cifrado null. Si una cuenta protegida por la clave de cifrado null se ve comprometida, los propietarios del sistema deberán elegir entre la seguridad y la disponibilidad.

Ejemplo 1: El código siguiente realiza el cifrado AES con una clave de cifrado null:


...
CCCrypt(UInt32(kCCEncrypt),
UInt32(kCCAlgorithmAES128),
UInt32(kCCOptionPKCS7Padding),
nil,
0,
iv,
plaintext,
plaintext.length,
ciphertext.mutableBytes,
ciphertext.length,
&numBytesEncrypted)
...


No solo permitirá a cualquiera con acceso al código determinar que se está usando una clave de cifrado null, sino que cualquier usuario malintencionado podrá descifrar datos cifrados con gran facilidad. Una vez que se haya distribuido el programa, se requiere una revisión del software para cambiar la clave de cifrado null. Un empleado con acceso a esta información podría utilizarla para irrumpir en el sistema. Si los usuarios malintencionados tienen acceso al ejecutable de la aplicación, podrían saber que se está usando una clave de cifrado null.
