Description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. 16 file-manager endpoints in Termix prior to version 2.3.2 do not verify that the requesting user owns the SSH session identified by `sessionId`. An authenticated attacker who knows or guesses another user's active `sessionId` can read, write, delete, download, and execute files on the victim's connected 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.
