Descriptions

Jellyfin is a system for managing and streaming media. Prior to version 10.8.13, the `/System/MediaEncoder/Path` endpoint executes an arbitrary file using `ProcessStartInfo` via the `ValidateVersion` function. A malicious administrator can setup a network share and supply a UNC path to `/System/MediaEncoder/Path` which points to an executable on the network share, causing Jellyfin server to run the executable in the local context. The endpoint was removed in version 10.8.13.

Jellyfin es un sistema para gestionar y transmitir medios. Antes de la versión 10.8.13, el endpoint `/System/MediaEncoder/Path` ejecuta un archivo arbitrario usando `ProcessStartInfo` a través de la función `ValidateVersion`. Un administrador malintencionado puede configurar un recurso compartido de red y proporcionar una ruta UNC a `/System/MediaEncoder/Path` que apunta a un ejecutable en el recurso compartido de red, lo que hace que el servidor Jellyfin ejecute el ejecutable en el contexto local. El endpoint se eliminó en la versión 10.8.13.
