CyberRota Analysis

AI-Generated

Termix, a web-based server management platform, is vulnerable to a critical issue that allows authenticated low-privileged users to manipulate the terminal WebSocket to authenticate to an attacker-controlled SSH server. This exploitation can lead to the disclosure of another user's stored SSH passwords or private-key materials when the victim's data key is unlocked. Organizations using versions prior to 2.3.2 should prioritize patching to mitigate this severe risk.

Original NVD Description

Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to 2.3.2, the terminal WebSocket accepts a user-controlled hostConfig.id and src/backend/ssh/host-resolver.ts resolves that host without requiring ownership or explicit access. When no credential is shared with the requester, resolveHostById performs an owner credential fallback, and src/backend/ssh/terminal.ts combines that credential with attacker-controlled ip, port, and username values. An authenticated low-privileged user can therefore make Termix authenticate to an attacker-controlled SSH server and disclose another user's stored SSH password or private-key material while the victim user's data key is unlocked. This issue is fixed in version 2.3.2.
