Technical 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
