Technical details
An authenticated OS command injection flaw exists in the devices.lua template handler in XWEB EVO 5.2.3–5.8.8. Unescaped template variables are passed directly into unzip and shell commands via the wlua interpreter, allowing authenticated attackers to inject arbitrary shell metacharacters and execute commands as root. No known public exploit code exists, but the attack requires only valid authentication credentials.
