Actually never mind that, it turns out I can just send
NDR.wstring("\x00") instead of including a string.



Just a suggestion, but IMHO if IDS evasion is the name-of-the-game, then an
empty NULL terminated string where UNC paths are normally expected would be
more 'abnormal', than something like:

NDR.wstring("\\"+Rex::Text.rand_text_alphanumeric(rand(10)))

.. which more closely matches the traffic produced by a typical legitimate
request.
