Low risk48th percentile - higher than 48% of all known CVEs
Summary
Termix prior to version 2.1.0 contains a command injection vulnerability in Docker container management endpoints, where the containerId parameter is directly interpolated into shell commands, allowing an authenticated attacker to achieve remote code execution on the managed server.
Risk Assessment
An attacker can take control of the managed server, leading to a breach of data confidentiality, integrity, and availability, and potential lateral movement.
Recommendation
Immediately update to version 2.1.0 or later and implement input sanitization on all endpoints.
Original NVD description (English source)
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.
