Subject: Re: Bad news on RPC DCOM vulnerability

There is not much info there, the site basically goes on saying that somebody
("karlss0n") posted the exploit  http://www.securitylab.ru/_exploits/rpc2.c.txt
to their bbs, the exploit is not using fixed jump addresses, which makes it work
with several versions of Windows. 

Then somebody has tried it against a patched XP and it seems to be working. 
Currently this exploit can be used for a shell on an unpatched (ms03-039) XP
(they say you need to put a shellcode into file bshell2 and fix a couple of
offsets, the sample code is at http://www.securitylab.ru/_exploits/shell.asm.txt)

On a patched XP this sploit only produces a DoS.

the discussion is here -
http://forum.securitylab.ru/forum_posts.asp?TID=5642&PN=1&TPN=3 ,more
informative, they talk about using SEH.

P.S.  I am not associated with anybody from this site/posting in; I am simply
translating the site for those who cannot read Russian, because online
translators are shite :)
