CVE-2026-42454 Details
Description
Termix is a web-based server management platform with SSH terminal, tunneling, and file editing capabilities. Prior to version 2.1.0, all Docker container management endpoints in Termix interpolate the containerId URL path parameter and WebSocket message field directly into shell commands executed via ssh2.Client.exec() on remote managed servers without any sanitization or validation. An authenticated attacker can inject arbitrary OS commands by crafting a malicious container ID, achieving Remote Code Execution on any managed server. This issue has been patched in version 2.1.0.
A remote code execution vulnerability has been identified in Termix versions prior to 2.1.0. The issue arises in all Docker container management endpoints, where the 'containerId' URL path parameter and WebSocket message field are directly interpolated into shell commands. This interpolation occurs without any sanitization or validation, allowing authenticated attackers to inject arbitrary operating system commands. The injected commands are executed on remote servers via SSH, potentially leading to a full compromise of the managed infrastructure.
Users are advised to validate the 'containerId' parameter against a specified regex pattern before use, or to utilize the Docker Engine API via HTTP instead of executing shell commands.
