|
|
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.
|
|
|
|
This module has been tested successfully on HP Client Automation 9.00 on Windows 2003 SP2
|
|
and CentOS 5.
