OS Command Injection in Termix resolvePath Endpoint

IdentifiersCVE-2026-45744CWE-78· Improper Neutralization of Special…

CVE-2026-45744 is an OS command injection vulnerability in Termix, a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. The flaw affects versions prior to 2.3.2 and is present in the GET /ssh/file_manager/ssh/resolvePath endpoint. According to the provided advisory, the endpoint constructs shell commands using double-quote escaping, but that escaping is insufficient because it does not prevent shell command substitution via $(...) or backticks. As a result, an authenticated user who has an active File Manager SSH session can inject shell metacharacters into input processed by resolvePath and cause arbitrary commands to be executed on the connected remote host.

ANALYST BRIEF

Impact, mitigation & remediation

What it means. What to do now. Patch path, mitigations, and the assume-compromise checklist.

Impact

What an attacker gets, and what they’ve been doing with it.

Successful exploitation allows arbitrary command execution on the remote host associated with the victim Termix SSH/File Manager session. Given the stated CVSS vector (AV:N/AC:L/PR:L/UI:N/S:C/C:H/I:H/A:H), impact includes full compromise of confidentiality, integrity, and availability on that connected host within the scope of the established SSH session, potentially enabling data access, file modification, destructive actions, and further pivoting depending on the privileges of the remote account in use.

Mitigation

If you can’t patch tonight, do this now.

If immediate upgrade is not possible, restrict access to Termix to only trusted administrators, disable or limit File Manager SSH functionality where feasible, and prevent untrusted users from establishing or using SSH-backed file management sessions. Apply network access controls to the Termix interface, monitor requests to /ssh/file_manager/ssh/resolvePath for suspicious command-substitution patterns such as $(...) and backticks, and review logs and remote shell histories for anomalous commands. These are temporary risk-reduction measures and do not replace upgrading to 2.3.2 or later.

Remediation

Patch, then assume compromise.

Upgrade Termix to version 2.3.2 or later, as version 2.3.2 is identified as the patch release for this issue. Review the vendor's release and associated security advisory to ensure the fixed code is deployed everywhere Termix is installed. After patching, rotate or review any credentials and inspect remote hosts reachable through Termix for signs of command execution abuse if exploitation is suspected.
