This module exploits a code execution flaw in HP SiteScope.
The vulnerability exists in the opcactivate.vbs script, which
2013-09-06 04:25:41 +00:00
is reachable from the APIBSMIntegrationImpl AXIS service, and
uses WScript.Shell.run() to execute cmd.exe with user provided
2013-09-09 20:09:53 +00:00
data. Note that the opcactivate.vbs component is installed
2013-09-06 04:25:41 +00:00
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.
