Name of the Vulnerable Software and Affected Versions Termix versions prior to 2.1.0

Description Termix is a web-based server management platform providing SSH terminal, tunneling, and file editing capabilities. The 'extractArchive' and 'compressFiles' endpoints in file-manager.ts use double-quoted strings for shell command construction. This implementation allows $(command) substitution, which enables command injection on the remote SSH host.

Recommendations Update to version 2.1.0.
