Overview

Affected versions of this package are vulnerable to Remote Code Execution (RCE) via the ValidateVersion function. An attacker with administrative access can set up a network share and supply a UNC path to the /System/MediaEncoder/Path endpoint, which points to an executable on the network share, causing the server to execute the file in the local context.
