Vulnerability Title
Termix Vulnerable to Remote Code Execution via SSH Tunnel Forward Command Injection
Source: NVD (National Vulnerability Database)
Vulnerability Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. The `POST /ssh/tunnel/connect` endpoint in Termix prior to version 2.3.2 builds an SSH tunnel command by interpolating user-controlled host record fields (`endpointIP`, `endpointUsername`, `password`) directly into a shell command without escaping, allowing persistent OS command injection on the source SSH host. Version 2.3.2 patches the issue.
