IE Flaw Gives Hackers Access To User Files
snydeq writes "Microsoft warned that a flaw in IE gives attackers access to files stored on a PC under certain conditions. 'Our investigation so far has shown that if a user is using a version of Internet Explorer that is not running in Protected Mode an attacker may be able to access files with an already known filename and location,' Microsoft said in a security advisory. The vulnerability requires that an attacker knows the name of the file they want to access, according to the company."
Had Microsoft not needed something to drive a stake through Netscape's heart, it wouldn't have needed to concoct it's own Frankenstein's monster of confused and misbegotten priorities.

it really whips the user's ass :)
Yet another reason for games to stop using IE as their built in patcher/notification/whatever. If you really need to display an HTML file, let the system display it with whatever the configured default is.
When you go to my website I know what the cookie name is and I know the default file system location for that cookie. This one seems pretty bad.
I wonder how many people have a "passwords.txt" file in their Documents. ;-)
an attacker may be able to access files with an already known filename and location
One more reason not to keep your files in "My Documents". That part is easily guessed; "2009 Income Tax Returns" would be easy to guess as well.
"Protected Mode prevents exploitation of this vulnerability and is running by default for versions of Internet Explorer on Windows Vista, Windows Server 2008, Windows 7, and Windows Server 2008," it said.
Does XP have a protected mode? That's the version of Windows most people use IINM. Is this a ploy to get people to upgrade from XP?
Microsoft hasn't seen any attacks that exploit the flaw and has yet to decide whether to repair the flaw through its monthly security patch release cycle or an urgent, out-of-cycle update.
Has yet to decide whether to repair it? Hmmm... Ok, they're trying to decide when to. How about doing what every other browser company does and give us the patch NOW?
Free Martian Whores!
Hmm.. the most obvious predictable file names are conveniently the most dangerous for someone to have access to.
Core Security Advisory FTW
This is just fucking stupid. WHY DO PEOPLE AND BUSINESSES STILL USE IE?
We KNOW it's full of holes. Not just small ones, but literally, gaping goatse-sized holes. This is a perfect example, to go along with the hundreds of other problems we know of.
There are so many alternatives today! We are living in a time of plenty when it comes to browsers. I mean, we have Opera that runs just about everywhere. We have Firefox if you want extensibility. If you prefer the feel of the old Netscape Communicator suite, there's Seamonkey. If you want a fast browsing experience, use Chrome or Safari or Konqueror.
Legacy ActiveX controls just aren't enough of an excuse these days. If you're still using that piece of shit "technology", then you need to get your network off of the public Internet. You and your network are nothing but a disaster waiting to happen.
The last time I dealt with "protected mode" on a 80286 CPU when DOS ruled the world. I had an ISA memory card that could page memory above the 1024K limit for applications or as a RAM drive.
Huh... what folder names are on almost all MS machines?.. yea that's a hard one
c:\windows\system\kernel32.dll?
I have a plan. Using mainly spoons, we'll tunnel our way out of the city...
... is how online virus scanners work. They know the name of all default install files on my pc. I wonder how they work when browser is firefox running on linux? And what do they find?
"The vulnerability requires that an attacker knows the name of the file they want to access, according to the company."
Good thing no one knows to look for: "%USERPROFILE%\My Documents\Quicken\qdata.qdf"
Modifying hosts.txt could be one of the biggest issues with this one. And yet, it's just another flaw much like there are hundreds of others in any browser.
Have you heard about SoylentNews?
NEW IMPROVED SECURITY IN WINDOWS VERSION 99999!!! *Slipped in a BSD *nix based OS under our fancy gui*
There is nothing to see here folks, move on. The bug kicks in only under certain circumstances. The circumstances are apparently running a Windows system with Internet Explorer as the default browser. Come on, how many slashdotters do that?
sed -e 's/Chuck Norris/Rajnikant/g' joke > fact
If they grab the windows search index file then they'd have a map to everything else?
get \ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb (vista)
or \All Users\Application Data\Microsoft\Search\Data\Applications\Windows\Windows.edb (xp)
and http://www.simplecarver.com/tool.php?toolname=Windows Search Index Extractor
Hi have tourettes. This manifests in two situations, when ordering at a drive-thru and, oddly, when coming up with a file name. I think I am safe from this attack: whoreShitSlittySlutFuckCrevice.rtf
In post Patriot Act America, the library books scan you.
Hmmm. Looks like I might have to buy an iPad sooner than I was expecting.

I run IE in Firefox mode, so I think I'm protected. ;)
If you purposefully disable security features, you become more vulnerable to security exploits!
Duh.
Need help treating your acne? Come here!
Couldn't you access some kind of index file that would allow you to find everything else? Or are those files too low level for it to be accessed this way?
Mod parent UP!
Hmmm. Does that mean I should rename the passwords.txt file I have on my desktop? Maybe something like kittens.txt? That sounds more secure to me. What do you think?
That part is easily guessed; "2009 Income Tax Returns" would be easy to guess as well.
Oh shit ... hackers can find out how broke I really am!!
Because there isn't an easily found, well known file that is a handy index of all of the files on your system:
\ProgramData\Microsoft\Search\Data\Applications\Windows\Windows.edb
http://en.wikipedia.org/wiki/Windows_Search
You mean like...
C:\users\%username%\AppData\Local\Microsoft\Outlook\outlook.pst?
hmmm...??? like that?

If things keep going like this regarding Microsoft and clever words, pretty soon this will be on Slashdot:
"Microsoft has announced that it is investigating a vulnerability in IE where an attacker can gain access to customer's computer if they are connected to Internet. But as all versions of Windows do not have internet access by default, most users are not vulnerable"
.
Protected Mode is the "sandbox" feature present in IE7 and IE8. It uses UAC that's in both Vista and 7 to run in an even more limited fashion, but not in XP. If you've got UAC disabled, you're not running Protected Mode and you're vulnerable. There are other ways which Protected Mode can be disabled.
It's best to check out the blog entry on the MSRC and the Knowledge Base article.
We now return to your regularly scheduled Microsoft bashing and Linux referrals already in progress.
The road to tyranny has always been paved with claims of necessity.
My friend had one for passwords to loads of sites he visited.
When his computer was screwing up, i suggested a reinstall of OS.
Went through the mess, even after him saying "there's nothing i need to backup", then remembered the passwords.txt on his desktop...
Luckily we were able to recover it because he had a copy on a flash drive.
I really don't understand why people risk having password files / sticky notes.
Even doing something like your name / word + some unique number + some random color is enough for a decent password. (caps on one side of the number)
A password should be like remembering a phone number, or a birthday.
And if you reaaaally wanted to go as far as making unique passwords for every site, use the main section of the domain, convert it to numbers, append it on to the end.
How about the system doesn't allow the fecking web browser to read your personal files? The purpose of My Documents is to have an easy space to store everything and keep it organized. How is the solution to this ridiculous bug to not utilize such a useful feature?
I like to think of online DRM as something akin to a college -- you pay for lessons until you learn something.
Nobody knows where i keep THIS file.
So you turn off something called "Protected Mode" and you're surprised that this may cause problems?
I know I do, it is the file contains my TrueCrypt volume for passwords, etc.
Another reason...why not to use IE, ....EVER!
The lmhost file point any common web addresses to a malicious site ...have fun as hundreds of trojans and viruses run rampant.
Someone who has used more than one OS: Microsoft sucks. Someone (fanboy) who has only used Windows(TM): Linux/BSD/HURD sucks. Peggy Mann: There's so much we don't know (and we wish to remain ignorant until we can prove a negative). RIAA: What about the starving musicians. Me: I need more coffee.
So that's what happened to my 8" bastard mill file.
slackware does
hahaha.. mahahahaha! yeah, windows is so secure... you are fucked again you stupid windoof fanboi faggots!
If it is possible to modify others' files through this flaw, what keeps someone from injecting code into an executable and change a highly-used shortcut? The curse of the large userbase...
I was listening to the radio, and I actually heard that lady Kim Komando tell people "you need to stop using Internet Explorer.". It made me laugh, seeing as how IE is evil and all.
This security exploit *really* looks bad on Microsoft, having been unveiled so close to the last one and all.
IE gives attackers access to files stored on a PC
This is news?
If they are savvy enough to disable the NoScript add-on, they are savvy enough to pick Allow this website when a video won't play. It's hardly "complex". Annoying? sure... but getting infected with something is a whole lot more annoying.
You give up a bit of convenience for safety, there's simply no way around it.

Surely the environment variable wouldn't work on a remote computer, at best they would get their own home folder (w00t), at worst it wouldn't find a directory on the remote computer as it is looking for blackhat's username
"The vulnerability requires that an attacker knows the name of the file they want to access, according to the company." Fat lot of good that does, all the files that are important to your *system* are all named the same on any Win computer, they could do some serious damage that way. Not to mention they could use those files to easily find every file on your computer due to indexing.

I can't even begin to tell you the number of sites required by my previous employer that required IE, and there's always a couple here and there that want ActiveX or what have you.
It's 2010. Can you list the sites here, and I'm sure someone will "evangelise" them into updating! :D
Seriously though - please do list them!
