Refer to oversized.txt for all the details. Remember, there are quite probably several 3rd party applications out there which rely on the MAX_PATH limit. I found it particularly shocking to find such a disturbing lack of functionality in the windows shell itself - but if you can come up with further ideas for exploitation ... you could tell me ... or not.
There appears to be a severe lack of python bindshells out there. I just don't like the thought that perl could be actually required for anything. Here you get 2 little scripts that both spawn a shell - The first one is fancy, the second one is small. The default password for bind.py is "bl0wfish". Enjoy!
