It has been while story about SMB version 2 vulnerability since this post. Finally public exploit to take over control windows vista SP1 and SP2 are out! You can catch the exploit at exploit-db.

Microsoft SRV2.SYS SMB Negotiate ProcessID Function Table Dereference
---------------------------------------------------------------------

Exploited by Piotr Bania // www.piotrbania.com
Exploit for Vista SP2/SP1 only, should be reliable!

Tested on:
Vista sp2 (6.0.6002.18005)
Vista sp1 ultimate (6.0.6001.18000)

Kudos for:
Stephen, HDM, Laurent Gaffie(bug) and all the mates i know, peace.
Special kudos for prdelka for testing this shit and all the hosters.

Sample usage
------------

> smb2_exploit.exe 192.167.0.5 45 0
> telnet 192.167.0.5 28876

When all is done it should spawn a port TARGET_IP:28876

RELEASE UPDATE 08/2010:
----------------------
This exploit was created almost a year ago and wasnt modified from that time
whatsoever. The vulnerability itself is patched for a long time already so
i have decided to release this little exploit. You use it for your own
responsibility and im not responsible for any potential damage this thing
can cause. Finally i don't care whether it worked for you or not.

P.S the technique itself is described here:

For your information, two days later at 19th August 2010, Kingcope released root exploit for FreeBSD 8.x and 7.x by poisoning mbufs() function. You may download Kingcope’s exploit here. Now happy exploiting while waiting “SAHUR” guys!

The latest version of freebsd is found to be vulnerable. This vulnerability is found in run time link editor (rtld) which can be tricked to accept LD variables even on setugid binaries. You might see this flaw by analyzing this exploit.

With this leaked exploit, it’s more than 10 exploitable vulnerability leaked to public this year (2009)! So it’s that true if freebsd as secure as what people said?!

I just look arround on milw0rm today and searching for linux kernel exploit, luckily i find four new linux kernel exploits.

• First exploit is to attack linux kernel locally using exit_notify() function vulnerability. This flaw affects linux kernel less than 2.6.29 (most of linux kernel). Just take a look here for the proof of concept.

• Second exploit is to attack linux kernel locally using UDEV vulnerability. Udev less than 1.4.1 is reported that it doesn’t verify wheter a NETLINK message originates from kernel space, which allows local users to gain root priviledge by sending a NETLINK message from user space. Let take a look here and here for the proof of concept.

• Third exploit is to attack linux kernel remotely using SCTP FWD memory corruption. Some people say this bug isn’t exploitable untill sgrakkyu gives his explanation. Sgrakkyu explanation can be read here, take a look here for the proof of concept. This flaw affects most of linux kernel.

• Fourth exploit is to attack linux kernel locally using ptrace_attach() function vulnerability. This flaw affects linux kernel version 2.6.29. Just take a look here and here for the proof of concept.

Now i just think, which is more secure by default “linux or windows??“, even openbsd which’s claimed as the most secured operating system has a stupid bugs inside its code.
