Description

Incorrect Access Control in the HTTP API module in ZLMediaKit commit 9fd5152 allows remote attackers to achieve Remote Code Execution (RCE) via unauthenticated access to the setServerConfig API endpoint, which permits overwriting the ffmpeg.snap configuration parameter with arbitrary shell commands. These commands are subsequently executed through the getSnap API endpoint with the privileges of the ZLMediaKit process.
