CVE-2021-26296 – Cross-Site Request Forgery (CSRF) vulnerability in Apache MyFaces

https://notcve.org/view.php?id=CVE-2021-26296

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. • http://packetstormsecurity.com/files/161484/Apache-MyFaces-2.x-Cross-Site-Request-Forgery.html http://seclists.org/fulldisclosure/2021/Feb/66 https://lists.apache.org/thread.html/r2b73e2356c6155e9ec78fdd8f72a4fac12f3e588014f5f535106ed9b%40%3Cannounce.apache.org%3E https://security.netapp.com/advisory/ntap-20210528-0007 • CWE-352: Cross-Site Request Forgery (CSRF) •
