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.

Affected products

• Termix-SSH Termix: from 2.1.0 before 2.3.2 — fixed in 2.3.2

How to fix

Upgrade to a fixed version: Termix-SSH Termix 2.3.2. Check the vendor advisory for mitigations.
