'Name' => 'CA Arcserve D2D GWT RPC Credential Information Disclosure',

'Description'=> %q{

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.
