Subject: Resolver behind NetFilter NAT service vulnerable to DNS poisoning attack
Date: Thu, 2 Sep 2010 15:50:08 +0200 [thread overview]
Message-ID: <AANLkTikVRqRjzzoRyDQzA0AiO1_kBNYiTwEZ2cLnsxhe@mail.gmail.com> (raw)
In-Reply-To: <AANLkTikjFnoh_=PX7YDv18O46JhLFnyXQ9-f2CEumqRd@mail.gmail.com>
We investigate some issues related to DNS poisoning, and specifically,
an attack that poisons DNS cache, similar to Kaminski's attack, but
that works even if the resolver selects random ports, as long as
resolver is connected to the Internet via NAT. In particular, we
tested the attack for the NetFilter NAT.
For obvious reasons, I prefer at this point to share details only with
developers of NAT devices. If you are such developer, please contact
me and I can send you the details (paper).
Feel also welcome to forward the messages to individuals/forums which
may be relevant (i.e., developers).
I apologize for not being able to promise to respond to requests from
people who are just curious (i.e., not NAT developers). Thanks for
your understanding.
