Input passed via the "url" parameter to login.php (when "do" is set to "lostpw") is not properly verified before being used to redirect users. This can be exploited to redirect a user to an arbitrary website e.g. when a user clicks a specially crafted link to the affected script hosted on a trusted domain. SOLUTION: Edit the source code to ensure that input is properly verified. PROVIDED AND/OR DISCOVERED BY: The vendor credits Robert Gilbert, HALOCK Security Labs.
