CVE-2026-42453 Details
Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.1.0, the extractArchive and compressFiles endpoints in file-manager.ts use double-quoted strings for shell command construction, unlike all other file manager operations which use single-quote escaping. Double quotes allow $(command) substitution, enabling command injection on the remote SSH host. This issue has been patched in version 2.1.0.
A command injection vulnerability has been identified in Termix, a web-based server management platform, in versions prior to 2.1.0. The issue arises in the extractArchive and compressFiles endpoints of the file manager, where double-quoted strings are used to construct shell commands. This allows for command substitution, enabling injection attacks on the remote SSH host. The vulnerability can bypass permission restrictions, exploiting deployments where the file manager is active but terminal access is disabled.
Users can upgrade to Termix version 2.1.0 or later, where this vulnerability has been patched.
