CVE-2026-45746: CWE-284: Improper Access Control in Termix-SSH Termix
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.3.2, the File Manager functionality in Termix contains a critical Broken Access Control vulnerability due to improper validation of the sessionId parameter. The backend trusts a client-controlled identifier without verifying that it belongs to the authenticated user. This allows an attacker to manipulate the value and access active File Manager sessions belonging to other users. Since these sessions are tied to SSH connections to remote VPS instances, exploitation allows unauthorized interaction with another user's remote filesystem. Because the File Manager exposes functionality such as file reading, writing, uploading, and execution, this vulnerability enables direct command execution on another user's VPS (RCE). Version 2.3.2 patches the issue.
AI Analysis
Technical Summary
CVE-2026-45746 is a critical Broken Access Control vulnerability in Termix's File Manager prior to version 2.3.2. The backend improperly validates the sessionId parameter, which is client-controlled, allowing attackers to hijack active File Manager sessions of other authenticated users. Since these sessions correspond to SSH connections to remote VPS instances, exploitation enables unauthorized file system access and remote code execution on another user's VPS. The vulnerability is fixed in Termix version 2.3.2.
Potential Impact
Exploitation allows attackers with at least limited privileges to bypass access controls and gain unauthorized access to other users' active File Manager sessions. This results in full read, write, upload, and execution capabilities on remote VPS instances connected via SSH, effectively enabling remote code execution and complete compromise of another user's VPS environment.
Mitigation Recommendations
Upgrade Termix to version 2.3.2 or later, which contains the official fix for this vulnerability. No other mitigation is indicated or required as the patch addresses the improper access control issue.
