        This module exploits a code execution flaw in HP SiteScope. The vulnerability exists in the
        APISiteScopeImpl web service, specifically in the issueSiebelCmd method, which allows the
        user to execute arbitrary commands without authentication. This module has been tested
        successfully on HP SiteScope 11.20 over Windows 2003 SP2, Windows 2008 and CentOS 6.5.
