Hacker Bags Windows Server 2008 Trophy
|
News Analysis. Could NETWORK SERVICE or LOCAL SERVICE be your worst security nightmare? |
My eWEEK colleague Ryan Naraine reports "serious design weaknesses" affecting Internet Information Services 7, Windows Server 2008, Windows XP and Windows Vista. IIS 7 is bundled with Windows Server 2008.
Exploit details are sketchy, but not the source: Argeniss co-founder Cesar Cerrudo.
Apparently, Cerrudo plans to share more information about the security flaws during April's Hack in the Box Security Conference. That will give Microsoft some time to research the problem before Cerrudo tells all. He plans to demonstrate zero-day exploits for elevating privileges in IIS, SQL Server and Windows Server 2008.
Assuming the exploits, or flaws, are really as serious as reported, they should be a reminder to Microsoft when the bug counting starts. Sometime in the next few months I expect Microsoft to count off the number of security vulnerabilities found in Windows Server 2008. Microsoft took this approach with Windows Server 2003 and Windows Vista in comparison with their predecessors. The counting tactic is flawed for lots of reasons, but here's a simple one: It's not the number but the severity that matters. One really bad flaw can be worse than 20, or 50, smaller ones.
Flaw counting is meaningful, just not the way it's used by Microsoft. Fewer vulnerabilities means fewer patches, which means fewer patch management headaches.
In the meantime, the question for enterprises to ask is, "When?" Are Windows 2008 and Windows Vista really enterprise security-ready? Some enterprises should consider a slower testing and migration path until more concrete information is available.
Microsoft has taken great pains to improve security in both operating systems. But Cerrudo has identified flaws with fundamental Windows services accountsNETWORK SERVICE or LOCAL SERVICEand claims the ability to seize control of exploited systems.
As I said, one really bad flaw is enough for concern. IT organizations should ask about the ease with which IIS 7 and either SQL Server 2005 or 2008 could be compromised for public-facing Web sites. Ryan reports that in IIS 7's default configuration, skilled hackers can completely compromise Windows Server security using ASP.Net applications.
One mitigating circumstance puzzles me: server roles. Apparently, Cerrudo didn't tell Ryan whether Windows Server 2008 can be compromised in all configurations or whether some server roles are less vulnerable than others. Windows XP and Vista don't use roles. But businesses can install portions of Windows Server 2008 for specific tasks. I haven't fully tested Windows Server 2008, so I can't say in what context, if any, the NETWORK SERVICE or LOCAL SERVICE accounts could be disabled.
At the time of my posting, Microsoft hadn't yet responded to Ryan's request for comment. Enterprises should listen to what Microsoft has to say, and then come back here or go to Security Watch for interpretation and analysis.

Just to make things clear: NETWORK SERVICE and LOCAL SERVICE are NOT "Windows services", they are special accounts with very limited rights. Various OS Services are configured to RUN IN THE CONTEXT OF local service of network service.

Windows Server 2008 has just been launched and the FUD has already started! :)
Sure, IIS 7 has a difficult task ahead to keep up the standard set by IIS 6 with its 0 (as in zero, none, zip, nada) security flaws last year but at let's at least wait a few months before claiming IIS 7 is a piece of security crap.
SQL Server 2008 has an even harder task, since it can't really beat SQL Server 2005 in the number of security flaws. I don't see how it can have -1 flaws...

Well, the feelings mutual from the Mac side too Joe: CNET News: MacBook Air hacked in security contest
The team had attack code already set up on a Web site, and was able to gain access to the MacBook Air and retrieve a file after judges were "tricked" into visiting the site. According to the TippingPoint DVLabs blog, a newly discovered vulnerability in Safari was used to gain control of the Air.
Last year's contest was won by exploiting a QuickTime vulnerability, which was patched by Apple in less than two weeks. As of the time I posted this, no one had gained control of the Vista or Ubuntu machines, but I'll update later as the results come in over the rest of the afternoon.

McAfee Inc., Trend Micro Inc., CA Inc. and especially Symantec, ... say goodnight! We are about to announce MS ForeFront 2.0!
Let me make it clear that while I have tolerated these "anti-virus" vendors for years, something about their very existence has not set very well with me. I mean, having a bunch of multi-million dollar companies that depend solely on there being bugs, leaks, holes, exploitables, mistakes, oversights and problems in Windows dosen't speak very well of Microsoft. They are like carrion, buzzards, jackels, ... protecting a rotten carcass from other smaller vermin. They always argue, "But, Bu-bu-but you need us!", maybe that was true in the past, but no longer!
VISTA IS BULLETPROOF!
None of these quacks bag of tricks are any longer necessary!
Between WGA and Forefront the OS and Genuine MS apps are totally impervious to attack! They are so secure that many times even the registered owners have trouble gaining access to the computer! So then how could any hacker?
These vultures will kick, choke and whine as the user-base realizes this truth, but I say good riddance, your success reflected badly on us anyway.

Joe, its interesting you did not approve the comment I made about OS X's Safari recently being hacked. Thanks for proving who you really are.

The potential "mitigations" that I wonder about
are not whether or not I can disable the
LOCAL_SERVICE and/or NETWORK_SERVICE accounts,
but whether or not, and if/so, which granular
(as in individually "flagged") Security
Privileges, granted to LOCAL_SERVICE and
NETWORK_SERVICE, can be flagged "Disabled,"
as a viable interim mitigation. I also have to
ask if Cerrudo's exploits require local console
access of if they can be achived remotely.
All users accounts in M$' Win-dom are a
specific collection of enabled or disabled
granular Security Privileges. Why can't
we get at least that much under-the-hood?
Some Services, but not all, require the
SetImpersonatePrivilege.
Would selective (via scripting) disabling of
SetImpersonatePrivilege stop Cerrudo's
exploit?
Cerrudo is not just talking about W2k8S.
He's also tarred XP, W2k3 & Vista, which are
all being used in production.
WhiteHats need actionable news and insight,
not next-to-useless FUD.

Press realease http://www.argeniss.com/pressrel032408.html seems to be very clear, I don't see FUD there

There is plenty of FUD in the Argeniss
"teaser."
It is orders of magnitude more difficult to
defend/protect than it is to attack/damage.
What Cerrudo alleges is fully plausible
and likely to be true.
The FUD is over what to do in the real world
with this information?
Cerrudo has dropped significantly more
*actionable* clues for the BadGuys than
for sysadmins who have got production
systems to defend/protect.
There is a clear measure of haughty arrogance
to all of this as well.
It is not at all clear to me that the
BadGuys haven't already discovered Cerrudo's
new "wheel" for themselves.
If so, Cerrudo's fig-leafed self-promotion
has set an April shot-clock for when the
BadGuys should plan on spending these exploits,
assuming that M$ is Johnny-on-the-Spot with
QFEs.
If M$ treats this like they did MSJETDB, then
the BadGuys will have a much longer window
of opportunity during which to mount Hit and
Run ops.

NEWS :
With Vista breached, "LINUX UNBEATEN IN HACKING CONTEST."!!
With Vista being hacked Friday, a Linux laptop was the one system that did not get compromised at the CanSecWest PWN 2 OWN hacking contest this week.
Using the Softies theory about market-share vs. security. Windows 2008 server market share = 0.01, explain pls.
conclusion; Windows is "Swiss cheese" regardless of %90 or %.01 market share.

Andre Da Costa, Trit and portuno asked about blocked comments.
No comments are approved on Microsoft Watch. Comments post automatically UNLESS they contain links. Right now, the IT staff has set all comments containing links to go to Junk. Because of the ridiculously large amount of junk, I do not search the folder.
There is no censorship at Microsoft Watch. Andre, I found your junked comment (with a link) and manually published it. Trit, I found no comments under that name.
My advice: Either don't put in links or use partial links. In the near future, when we switch blogging platforms I will insist on a mechanism, such as CAPTCHA, to reduce comment spam while making it easier for legitimate readers to comment.
Andre and Trit, my apologies for your junked comments.

Dear n0neXn0ne, Vista WASN'T hacked, ADOBE FLASH WAS. The hacker who won the vista laptop said the exploit would work on any OS that has flash. You were saying?

"Vista WASN'T hacked, ADOBE FLASH WAS."
@ James G. :
Vista was hacked and Ubuntu was not!
@James :
Adobe was the entry point to take over the OS. All OSes run applications, and if an OS can be comprised thru the application layer, then there is something fundamentally wrong with the OS. Hence a bug in an application does not constitute an OS being taken over.
FYI : Ubuntu and Linux uses AppArmor and SELinux
Hope I clarified it a bit ;)
By the way, what if it was Ubuntu being hacked?
Would you have been so defensive for Ubuntu?
Score:
Vista 1
Mac 1
Ubuntu 0
--------------
Game over

@James G :
Hackers take the path of the least resistance.
If Ubuntu was easy someone would have done it in 2 mins.

There is no publicity in hacking Linux, all hackers know that it's the easier to hack

Tim :

Tim, excuse me while I laugh at your complete lack of knowledge. Everyone knows that Windows is the easiest OS to attack, because MSFT was never concerned about security. Windows was/is based on MSDOS, which was setup as a one person desktop operating system. Therefore, there was never any real security ever built into it, unlike Unix/Linux/BSD Operating Systems, which were originally made for networking over large office systems.

Absolutely, hackers do what is most elegant and simple to get what they want. It might be hard to coin it in this way, but it's the truth. I am a CIO, and I will not allow under any circumstance IIS or Exchange to be running anywhere on the company premises. IMHO, a box with IIS running should not have a direct Internet connection. We use Centos servers and apache for all internet servers, custom built postfix for company mail, and have custom compiled hardened BSD boxes as gateway firewalls. My BSD firewalls were built with legacy PIII chips and I have never seen one of them use more than 18% resources at full load. My point being, you do not need these high resource intensive and security issue laden bundled web services to provide everything you need for an enterprise business. There are more secure solutions that perform better to be found open source. As for windows and security in general, so long as anybody who can buy visual basic can compile a program that can be executed on a windows desktop that will overwrite the windows kernel o.s. of that desktop... it will never be secure.

Point 1: It IS Microsoft Windows products. And yes they have MAJOR market share. But a bad product is a bad product, market share be damned.
Point 2: MS products receive the most attention because they are the easiest to compromise. If other OS's were as easy to attack, then they would be. Do crackers care about market share, or about ease of access? A thousand Linux/Mac/Unix boxes or a thousand MS boxes, is still a thousand cracked boxes.
Point 3: It may have been an app that was compromised during the event. But why did they not chose to use that app to compromise the Linux box instead. Or the Mac box for that matter?
Point 4: Look not at the total number of issues per platform. But at the time from when that issue is announced to the time that it is fixed. For other platforms it can be a matter of just a few days ( or even hours ). Compared to the weeks, or even months for MS products. That is if you can even get them to admit that there is a problem. And if the fix isn't worse the the issue it "fixes".
Microsoft products have always had problems. And they always will. This is true because Microsoft is not interested in "quality" products. They are only interested in getting your money. They are not interested in the security of their products. They are only interested in "locking" you into their products. So that they can get more of your IT dollars. They could care less, as long as you keep giving them your money.
Pointing at the fact that other platforms have problems also, is meaningless. It does not make Microsoft products any better, any more secure. It does not alter the fact that Microsoft products are the most often attacked/compromised products. It changes nothing.
The fact is that Microsoft makes inferior products, security wise, when compared to other platforms. Period. Plain and simple. If you want security, then look at some other platform. There are many and they are very good. If you are not concerned, or just don't care, then stay with Microsoft. They are not concerned and don't care either. As long as you give them your money.
Me, I care. That's why I use several of the other platforms.
