## Technical details

The api.lua module in XWEB EVO concatenates user-supplied server_url and credential fields directly into a root-level curl command executed via io.popen without proper escaping, enabling OS command injection. Exploitation requires authentication to the web interface but results in unauthenticated remote code execution with root privileges on the underlying system. A fix is available in versions after 5.8.8.
