'Name'=> 'HP SiteScope Remote Code Execution',

'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.
