        This module exploits a Remote Code Execution in the web panel of Phoenix Exploit Kit via the geoip.php. The
        Phoenix Exploit Kit is a popular commercial crimeware tool that probes the browser of the visitor for the
        presence of outdated and insecure versions of browser plugins like Java, and Adobe Flash and Reader which
