Re: Microsoft Windows vulnerability in TCP/IP Could Allow Remote Code Execution (2588516)

I've used Impacket to craft raw packets of all kinds. Then again I don't
know if that counts - used to work at Core at the time, so it was pretty
much the only choice due to licensing issues with other libraries.

I don't mean to say it's a bad tool to work with, not at all. I happen to
prefer the newer Scapy, but it's just a matter of personal taste. :)

Dear Dan,

Impacket was at first a Pysmb copy/update from Core Security in order to
play with RPC. (look at the source)
They've done some work on pysmb library in order to implement DCE/RPC
functionality in this dinosaurus lib.
Saying that we should use Impacket in order to craft *raw* UDP packet
is definitively the dumbest thing I've heard today. Seriously. Anyone can
confirm that ? Mario ? Carlos ? ....

Anyways, This guy doesn't understand shit, talks a lot about shit he
doesn't know about, why would you even spend time reading his shit ?

This vulnerability is about sending a *huge fucking* stream of UDP packets
on a closed port in order to trigger a int overflow via a ref count.
Most of the people here didn't even understand what we are talking
about/dealing with.

Anyways, it's probably time for you to unsubscribe since you don't follow
and S-K's like secn3t () gmail com are trying to act like they know.

Yeah right, a UDP int overflow triggered via a refcount UDP overflow that
you can trigger with 1 single TCP (with the right ACK) packet is the way to
go.

This mailing list is getting gay, seriously.

Cheers,
Antony.

Okay, now I'm confused! From
http://oss.coresecurity.com/projects/impacket.html

"Impacket is a collection of Python classes focused on providing access
to network packets. Impacket allows Python developers to craft and decode
network packets in simple and consistent manner. It includes support for
low-level protocols such as IP, UDP and TCP, as well as higher-level
protocols such as NMB and SMB. Impacket is highly effective when used in
conjunction with a packet capture utility or package such as Pcapy<http://oss.coresecurity.com/projects/pcapy.html>.
Packets can be constructed from scratch, as well as parsed from raw data.
Furthermore, the object oriented API makes it simple to work with deep
protocol hierarchies."

Thanks for your input Antony. Can you explain why impacket has nothing
to do with crafting UDP packets?

Fascinating thread this. Thanks to all!!

dan :)

You are definitely a lamer secn3t.
Also for you little brain, impacket has nothing to do with crafting UDP
packets..

Thanks for proving this again and again.

well look at that :P
not same author but , nice coding predelka! good one, i will add you
to crazycoders.com coderslist... i guess there is a few codes you have
now done wich might be useful... cheers.

I liked the "heavy breather in the perv closet" bit.

About the PPS, i think thats a very bad summary of the exploit,
49days
to send a packet, my butt.
There is many people assuming wrong things, when it can be done
with
seconds, syscanner would scan a -b class in minutes, remember it
only
has to find the vulns, gather, then it would break scan, and
trigger
vuln... so in real world botnet, yes then, with tcpip patchers,
like
somany ppl i know myself, even use (tcpipz)patcher ) , wich
rocks...
and it is ONLY one wich actually works, when you maybe modify the
src
so the sys file, is dropped from within a .cpp file, well thats up
to
you but thats better way to make it work, this will open
sockets/threads, as i could, easily proove with one exe, but, the
goal
is, to trigger the vuln then exploit it, less than 49days :P , so ,
iguess if this exploit, in real form, gathered 2 million hosts
over 3
nights.. i guessing that the exploit, could possibly be triggered
with
ONE properly setup packet.. people forget that, a packet is one
thing,
and a crafted UDP packet, is quite another..

I'd really like to see you actually explain this bug with code.
Either
with a poc or with the disassembly. You seem to act like you know
what's going on, but so far your description has been off base (from
what I can make of your writing).

No one cares about paragraphs of speculation and bragging, code or
you
are just another heavy breather in the perv closet of FD.
