      "value": "Jellyfin is an open source self hosted media server. Versions before 10.10.7 are vulnerable to argument injection in FFmpeg. This can be leveraged to possibly achieve remote code execution by anyone with credentials to a low-privileged user. This vulnerability was previously reported in CVE-2023-49096 and patched in version 10.8.13, but the patch can be bypassed. The original fix sanitizes some parameters to make injection impossible, but certain unsanitized parameters can still be used for argument injection. The same unauthenticated endpoints are vulnerable: /Videos/\u003citemId\u003e/stream and /Videos/\u003citemId\u003e/stream.\u003ccontainer\u003e, likely alongside similar endpoints in AudioController. This argument injection can be exploited to achieve arbitrary file write, leading to possible remote code execution through the plugin system. While the unauthenticated endpoints are vulnerable, a valid itemId is required for exploitation and any authenticated attacker could easily retrieve a valid itemId to make the exploit work. This vulnerability is patched in version 10.10.7."

      "value": "Jellyfin es un servidor multimedia autoalojado de c\u00f3digo abierto. Las versiones anteriores a la 10.10.7 son vulnerables a la inyecci\u00f3n de argumentos en FFmpeg. Esto puede aprovecharse para lograr la ejecuci\u00f3n remota de c\u00f3digo por parte de cualquier persona con credenciales de un usuario con pocos privilegios. Esta vulnerabilidad se report\u00f3 previamente en CVE-2023-49096 y se corrigi\u00f3 en la versi\u00f3n 10.8.13, pero el parche puede ser evadido. La correcci\u00f3n original sanea algunos par\u00e1metros para imposibilitar la inyecci\u00f3n, pero ciertos par\u00e1metros no saneados a\u00fan pueden usarse para la inyecci\u00f3n de argumentos. Los mismos endpoints no autenticados son vulnerables: /Videos//stream y /Videos//stream., probablemente junto con endpoints similares en AudioController. Esta inyecci\u00f3n de argumentos puede explotarse para lograr la escritura arbitraria de archivos, lo que puede llevar a la ejecuci\u00f3n remota de c\u00f3digo a trav\u00e9s del sistema de complementos. Si bien los endpoints no autenticados son vulnerables, se requiere un itemId v\u00e1lido para su explotaci\u00f3n, y cualquier atacante autenticado podr\u00eda obtener f\u00e1cilmente un itemId v\u00e1lido para que la explotaci\u00f3n funcione. Esta vulnerabilidad est\u00e1 corregida en la versi\u00f3n 10.10.7."
