AI Powered Q&A
Can you explain this vulnerability to me?
This vulnerability exists in Termix, a web-based server management platform. Before version 2.1.0, the extractArchive and compressFiles endpoints in the file manager used double-quoted strings to construct shell commands. Unlike other file manager operations that use single-quote escaping, the use of double quotes allows command substitution via $(command). This enables an attacker to perform command injection on the remote SSH host, potentially executing arbitrary commands.
How can this vulnerability impact me? :
The vulnerability can allow an attacker to inject and execute arbitrary commands on the remote SSH host through the vulnerable endpoints. This can lead to unauthorized access, data manipulation, system compromise, or disruption of services managed by Termix.
What immediate steps should I take to mitigate this vulnerability?
The vulnerability is caused by unsafe shell command construction in Termix versions prior to 2.1.0, allowing command injection via the extractArchive and compressFiles endpoints.
To mitigate this vulnerability immediately, upgrade Termix to version 2.1.0 or later, where the issue has been patched.
