MAXcms contains a flaw that may allow a remote attacker to execute arbitrary commands. The issue is due to the 'modul/mod.users.php' script not properly sanitizing user input supplied to the 'thCMS_root' parameter. This may allow an attacker to include a file from an arbitrary remote host that contains commands which will be executed by the vulnerable script with the same privileges as the web server.

Upgrade to version 3.16.9 or higher, as it has been reported to fix this vulnerability. An upgrade is required as there are no known workarounds.
