Description
XWEB EVO 5.2.3 through 5.8.8 contains an authenticated OS command injection vulnerability that allows authenticated attackers to execute arbitrary commands as root by injecting shell metacharacters into the output device path parameter processed by backup.lua. Attackers can exploit the unescaped concatenation into mount, unzip, and related shell commands run via the wlua interpreter, including through the setuid xwbackup.cgi and xwrestore.cgi interfaces, to achieve full system compromise. This product line reached it's end of service date in March 2026.
