Detection Guidance

This vulnerability involves OS command injection via the /stream-to-vlc Express route using the url parameter in hitarth-gg Zenshin before version 2.7.0.

To detect this vulnerability on your system or network, you can monitor HTTP requests targeting the /stream-to-vlc route and inspect the url parameter for suspicious or unexpected command injection patterns.

A practical approach is to use network traffic analysis tools or command line utilities such as curl or wget to test the endpoint with crafted payloads that attempt command injection.

• Use curl to send a test request to the vulnerable endpoint: curl -v 'http://<target-ip>:<port>/stream-to-vlc?url=;id'
• Check server logs for unusual command execution or errors related to the url parameter.
• Use network monitoring tools like tcpdump or Wireshark to capture and analyze traffic to the /stream-to-vlc route.

Mitigation Strategies

The primary mitigation is to upgrade hitarth-gg Zenshin to version 2.7.0 or later, where the vulnerability has been fixed by replacing the use of exec with spawn and binding the Express server to 127.0.0.1.

If immediate upgrade is not possible, restrict access to the vulnerable /stream-to-vlc route by firewall rules or network segmentation to prevent remote exploitation.

Avoid exposing the Express server to untrusted networks by binding it to localhost (127.0.0.1) as a temporary mitigation.

Review and sanitize all inputs to the url parameter to prevent command injection.
