CVE-2026-45748: CWE-78: Improper Neutralization of Special Elements used in an OS Command ('OS Command Injection') in Termix-SSH Termix
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.
AI Analysis
Technical Summary
Termix is a web-based server management platform that includes SSH terminal and tunneling features. In versions before 2.3.2, the POST /ssh/tunnel/connect endpoint constructs SSH tunnel commands by directly inserting user-supplied fields (endpointIP, endpointUsername, password) into shell commands without sanitization. This improper neutralization of special elements leads to a persistent OS command injection vulnerability (CWE-78), enabling remote attackers to execute arbitrary commands on the source SSH host. The vulnerability has a CVSS 3.1 score of 9.8, indicating critical severity. The issue is fixed in Termix version 2.3.2.
Potential Impact
Successful exploitation allows unauthenticated remote attackers to execute arbitrary operating system commands on the source SSH host, potentially leading to full system compromise, including confidentiality, integrity, and availability impacts.
Mitigation Recommendations
Upgrade Termix to version 2.3.2 or later, where this OS command injection vulnerability is patched. No other official remediation or temporary fixes are documented. Until upgrading, avoid exposing the vulnerable endpoint to untrusted users.
