Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.3.2, the GET /ssh/file_manager/ssh/resolvePath endpoint in Termix is vulnerable to OS command injection. The endpoint uses double-quote escaping for shell command construction, which does not prevent $(...) and backtick command substitution. Any authenticated user with an active File Manager SSH session can execute arbitrary commands on the connected remote host. Version 2.3.2 patches the issue.
