The vulnerability is caused due to an improper authorisation check in includes/userlevel_check.php when certain cookie parameters (e.g. "access" and "userlevel") are set to certain values. This can be exploited to perform certain actions with e.g. administrative privileges and e.g. create an administrative user. The vulnerability is confirmed in version 0.1 r80. Other versions may also be affected. SOLUTION: Edit the source code to ensure proper authorisation. PROVIDED AND/OR DISCOVERED BY: Simon Leblanc within a cFTP bug report.
