IE Zero-Day

i appreciate the interesting articles that others have posted in the forum and i have been thinking that i myself should try to contribute, so..

note that, according to "microsoft", only IE 6 - IE 8 are affected.. IE 9 and IE 10 are not affected.. also, the exploit relies on "flash player"..

"Attackers Target Internet Explorer Zero-Day Flaw"

Attackers are breaking into Microsoft Windows computers using a newly discovered vulnerability in Internet Explorer, security experts warn. While the flaw appears to have been used mainly in targeted attacks so far, this vulnerability could become more widely exploited if incorporated into commercial crimeware kits sold in the underground.

IEwarningIn a blog posting Friday evening, Milpitas, Calif. based security vendor FireEye said it found that the Web site for the Council on Foreign Relations was compromised and rigged to exploit a previously undocumented flaw in IE8 to install malicious software on vulnerable PCs used to browse the site.

According to FireEye, the attack uses Adobe Flash to exploit a vulnerability in the latest (fully-patched) version of IE8. Dustin Childs, group manager for response communications at Microsoft, said the vulnerability appears to exist in previous versions of IE.

“We are actively investigating reports of a small, targeted issue affecting Internet Explorer 6-8,” Childs said in an emailed statement. “We will take appropriate action to help keep customers protected once our analysis is complete. People using Internet Explorer 9-10 are not impacted.”

As FireEye notes, this is another example of a “watering hole” attack, which involves the targeted compromise of legitimate websites thought to be of interest to or frequented by end users who belong to organizations that attackers wish to infiltrate. Earlier this year, I wrote about similar zero-day attacks against visitors to the Web sites of the National Democratic Institute, The Carter Center, and Radio Free Europe.

Who the hell cares if IE6 is vulnerable?
Microsoft has to stop patching IE6 or people will continue to use it.

^^^ This. Why anyone would use such an old, outdated, insecure browser is beyond me. I'd like to say they deserve whatever happens, but that would be mean.

Microsoft Research & Defense: New vulnerability affecting Internet Explorer 8 users

quote:
In this particular vulnerability, IE attempts to reference and use an object that had previously been freed. The components of an exploit for such a vulnerability are typically the following:
• Javascript to trigger the Internet Explorer vulnerability
• Heap spray or similar memory preparation to ensure the memory being accessed after it has been freed is useful
• A way around the ASLR platform-level mitigation
• A way around the DEP platform-level mitigation

Internet Explorer 9 or 10 do not include the vulnerable code. And the IE team is working around the clock to develop a security update to address this vulnerability for earlier versions of the product. ...read full article

Not to sound like an idiot, but wouldn't referencing an object after it's been removed or freed up (made null) cause a Null Reference Exception? I know that that happens when I try to access Object variables when I've not set it to something with "New Object()".

This happens in VB.NET, C#, and even Java.

Companies that are too cheap to spend the money required to re-code or update the "broken" web applications they are using.

Yes, the company I work for still uses IE6. Several of the intranet web apps don't work properly on any other browser.

Is that a valid reason to still be using IE6? IMHO, it is not. They've had plenty of time and money to upgrade their web applications, instead they waste the budget elsewhere on less important things.

Says IE6 - IE8.
(Guess IE5 & earlier no longer count .)

> Microsoft has to stop patching IE6 or people will continue to use it.

And aren't XP users limited to (at most) IE8 (or another browser entirely)?

Yup.

Win2K users can't run anything higher than IE6. I use Firefox v12.0 (the last to run on Win2K) on the rare occasions I browse on that box.

IE 3.01 was the last to run on Win 3.1 and WfWG 3.11 (16-bit OS'es) Netscape lasted until 4.x from memory.

Microsoft Confirms IE Flaw, Releases Workaround

"Here are Microsoft’s recommendations for those still using Internet Explorer 8 or older:

• Set Internet and local intranet security zone settings to "High" to block ActiveX Controls and Active Scripting in these zones
• Configure Internet Explorer to prompt before running Active Scripting or to disable Active Scripting in the Internet and local intranet security zones
• Deploy the Enhanced Mitigation Experience Toolkit (EMET) ..."

(Wonder how usable the browser will be with the first two suggestions implemented .)

Well if you're "lucky" you're probably "happy" too

Probably not many bad guys targeting IE5 any more.

It's that other browser you use to download Firefox or Google Chrome with.

I haven't looked into it in any detail but apparently there's some rather clever techniques that can be used to access deallocated memory. Take a look at the EMET manual as it has basic explanations of some common tricks.
