Technical details
The vulnerability is an authenticated OS command injection in backup.lua that fails to escape shell metacharacters in the output device path parameter. The unescaped input is concatenated into mount, unzip, and related shell commands executed via the wlua interpreter, including through setuid xwbackup.cgi and xwrestore.cgi interfaces. An authenticated attacker can execute arbitrary commands as root via shell metacharacter injection.
