'Name' => 'Novell ZENworks Asset Management 7.5 Remote File Access',
'Description' => %q{
This module exploits a hardcoded user and password for the GetFile maintenance
task in Novell ZENworks Asset Management 7.5. The vulnerability exists in the Web
Console and can be triggered by sending a specially crafted request to the rtrlet component,
allowing a remote unauthenticated user to retrieve a maximum of 100_000_000 KB of
remote files. This module has been successfully tested on Novell ZENworks Asset
Management 7.5.
