Descriptions

In the default configuration, Apache MyFaces Core versions 2.2.0 to 2.2.13, 2.3.0 to 2.3.7, 2.3-next-M1 to 2.3-next-M4, and 3.0.0-RC1 use cryptographically weak implicit and explicit cross-site request forgery (CSRF) tokens. Due to that limitation, it is possible (although difficult) for an attacker to calculate a future CSRF token value and to use that value to trick a user into executing unwanted actions on an application.

En la configuración predeterminada, Apache MyFaces Core versiones 2.2.0 hasta 2.2.13, versiones 2.3.0 hasta 2.3.7, versiones 2.3-next-M1 hasta 2.3-next-M4 y 3.0.0-RC1, usan tokens de tipo cross-site request forgery (CSRF) implícitos y explícitos criptográficamente débiles. Debido a esa limitación, es posible (aunque difícil) para un atacante calcular un valor futuro de token CSRF y usar ese valor para engañar al usuario a ejecutar acciones no deseadas en una aplicación

Apache MyFaces versions 2.2.13 and below, 2.3.7 and below, 2.3-next-M4 and below, and 2.1 and below suffer from a cross site request forgery vulnerability.
