Apple iTunes Security Flaw Discovered? 207

Posted by Zonk from the unfortunate-song dept.
brajesh writes "CNET News.com is reporting that a critical vulnerability has been found in some versions of Apple's popular iTunes that could allow attackers to remotely take over a user's computer, according to a warning issued by eEye Digital Security, a security research firm. The latest iTunes flaw affects all operating systems from Windows XP to Mac OS X, according to the advisory. The discovery of this latest flaw comes days after Apple issued its iTunes 6 for Windows security update."

    Nothing yet, since details of the flaw won't be released by eEye until a patch is released by Apple.

    If someone is wondering "should I be worried", the answer is no; exploits of this nature are usually still theoretical and not being exploited en masse "in the wild". Many of these exploits are explicitly discovered by the security organizations who have released the advisories themselves and are often not necessarily representative of any actual exploit being applied maliciously: the idea is to catch security vulnerabilities before they are actually used maliciously. Further, the exploit in question probably requires the user to specifically visit a malicious web site (other than a port open via Rende..., er I mean, Bonjour, when iTunes Sharing is enabled, I don't know of any other avenue to exploit iTunes). The exploit must, therefore, pass a url and/or file to iTunes, and therefore would very likely require visiting a malicious web site.

    We don't know the details of the exploit, I can still say with it's extremely likely that it is not something that would be able to spontaneously occur simply by using iTunes in a normal fashion.

    This story would more accurately be:

    "Some unknown and unannounced flaw found in a piece of software; fix coming from software vendor"

    Is this news?

    (And it's amusing that if you buy a commercial product [eeye.com] from the vendor issuing the vulnerability, you'll be protected! Not a rip on eEye, who has discovered a good deal of vulnerabilities, but it's not as if many of these security entities themselves don't have an interest in finding "vulnerabilities", no matter how nebulous or unlikely.)

      I can still say it's extremely likely that there is no exploit or flaw at all. Why would anyone believe it? There's no evidence of any kind that any exploit or flaw exists, at all.

      This story would more accurately be: "Some unknown and unannounced flaw found in a piece of software; fix coming from software vendor"

      Close, but more accurate still would be: "Some security company trying to drum up business for itself says its product will protect users from a flaw they claim exists, but offer no details or evidence for."

        In fairness, eEye has discovered legitimate vulnerabilities that Apple has actually included in OS and security updates.

        However, I do agree with you.

        And further, it's impossible for this to a "remote execute" vulnerability like the stories based on the extremely vague advisory make it out to be: you can't even talk to iTunes remotely when it's running (unless you have iTunes Sharing enabled, which is available on your local subnet). Therefore, as I've said in another post, this vulnerability *must* be exploited via visiting a malicious web site, which then passes a url and/or file to iTunes. Period. That's the only way this could happen. It's not just something where if you run iTunes, all of a sudden you're vulnerable. Bravo to the way they've positioned it though. They probably floated out some media releases, too. I especially like the last line of the advisory:

        Protection: Blink Endpoint Vulnerability Prevention mitigates any potential exploitation of this vulnerability, without requiring a patch or invasive firewall actions.

        And, for what it's worth, eEye will release the "details", whatever they are, after Apple has patched whatever the issue is.

          Well, not impossible. Go to System Preferences -> Sharing -> Remote Apple Events. Turn it on. Now someone can do pretty much what they want with your system. If they have a valid username/password (or you turned on the Mac OS 9 password ... which wouldn't be a security flaw, but part of the design).

          I could, for example, do something like:
          glue Finder '$g->ADDRESS(eppc => Finder => "your.machine.example.com"); $g->obj(item => 1)->delete'
          That would be mean and cruel. And it works over the Internet. And it would also require me to have a username and password on your machine.

          And, for what it's worth, eEye will release the "details", whatever they are, after Apple has patched whatever the issue is.

          And if they do, I will care at that time. It's the height of irresponsibility to release details in this way. The only point is to scare people into buying their product. And therefore I consider it, until actual details emerge, a malicious hoax.
        • Just a thought... what if someone poisoned a podcast? Subscribe to kool sounding podcast, get malicious file via podcast auto-update. Possible attack-vector?
          • Not that I'm in any way an expert, but I tried to do something like that last weekend (for good reasons, I tell ya, good!) and it didn't work. iTunes seems to really check over the file you're grabbing, so unless there's a vulnerability in the mp3 player itself (embedding bad stuff in media files etc), I'm thinkin' it won't work.
      • Why would people believe it? Most likely because the company wouldn't want to be sued for libel [wikipedia.org] by Apple.

      • iTunes has a lot more attack surface than than just file sharing via Bonjour.

        Referring to "file sharing via Bonjour" makes as much sense as saying "file sharing via DNS". Bonjour/Rendezvous/ZeroConf is not a file sharing technology. It's multicast DNS. It's used to advertise the availability of a service - any service - to other hosts. Apple includes an Apache module, for instance, that uses Bonjour to advertise the presence of an HTTP server, and Safari uses Bonjour to look for them. But Bonjour's role
    • Of course, then you have to wonder how many of these vulnerabilities are discovered by Black Hats and never release information. Black Hats are probably sitting on hundreds of otherwise undiscovered exploits. There is no reason to believe that only "security organizations" can find exploits like this.

    Wow. Software has flaw allowing remote hackery. This seems to be pretty typical of just about any piece of software written these days (or any days.)

    I guess the question is, do we measure a company and its software by its base security, or by how quickly it responds to a discovered threat? I'm personally inclined to lean towards the second.

      Both, of course. The first shows how good they are at actually designing and creating software, and the second shows how much they listen to their users/their lawyers/the press. (Take your pick.)

      Both? I mean, yes, we should be forgiving of companies who have taken every reasonable step towards security when a flaw is found, so long as they patch it quickly. However, the process of securing your software shouldn't start at SP2. It should be ongoing during the development.

    Well, that's not a lot of info.
    All they say is: 'it's vulnerable! run for the hills!'.

    I don't use iTunes, so I don't really care, but what's the vector? Is it a malformed MP3/AAC file? Does iTunes run as a service that listens to a certain port, and can it be attacked through there (probably not likely, as I don't see why a music player should be listening to some port)?

    This lacks information, and you really can't do anything to protect yourself if you don't know how the hell the exploit works...

    With nothing more to go on than a couple vague sentences from eEye, here's my guess:

    One major thing that make iTunes different from other music player apps is the Music Store integration, which operates as a limited web browser. On OSX it calls WebKit; on Windows either Apple built a custom minibrower or it calls Explorer. Does anyone know which, BTW?

    In any case, this means that iTunes accepts URLs, specifically itms://[...]. It's also capable (on OSX at least) of launching your default browser and other URL helper apps. I'm guessing that Apple did a bad job validating input, and a malicious itms URL could trick iTunes into launching a remote file as if it were a helper app. Hence the local user context. If this is the case, simply viewing an evil web page (with the itms URL as a redirect/iframe/img/whatever) in most browsers should be sufficient to start the attack.

    Hopefully someone will divulge the facts soon. Let's see if I'm even close.
