Thanks Fernando. I'll take a look. It looks like a great read.

Could you provide references for the aforementioned vulnerability
(orphaned connections)?

Sure. I saw the vulnerability in the securiteam website.


From there, i did some research and tests. I wrote all the results in this
forum (Spanish)


You will find a proof of concept that i've implemented (not a brillant code,
it shows the vulnerability :P).
I don't send the PoC to the list because i don't know the rules.
Nevertheless, it's just a PoC.

@Valdis Kletnieks:
Have you ever found something by binary difference with windows patches?. If
it's humaly impossible, i'll drop this method and i'll try to send crafted
packets in a fuzzy manner but i needed ideas. I mean, guesses about the
possible implementation of the TS option.

vulnerabilitiy called "Microsoft Windows XP/Vista TCP/IP Orphaned
Connections Vulnerability" because i had more information. I'm testing
issue against a Windows Vista Ultimate SP1. I could patch it and then
compare the corresponding binary files.
Following your guesses i can start to try something buggy. Thanks.
