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.
