System Exploitable With USB 310

Posted by Zonk from the good-thing-no-one-uses-that dept.
Anonymous Coward writes "Vulnerabilities in USB drivers for Windows could allow an attacker to take control of locked workstations using a specially programmed Universal Serial Bus device." From the article: "The buffer-overflow flaw is in device drivers that Windows loads whenever USB devices are inserted into computers running Windows 32-bit operating systems, including Windows XP and Windows 2000, said Caleb Sima, chief technology officer and founder of SPI Dynamics."

      Yep. Got boot? You've got root.

      That said however, the Operating System should at least try to protect sensitive data - make it so the attacker is going to have to pull that hard drive out of the box & mount it from another machine to try & brute-force the password file (or whatever)

      Given enough time and resources, I have physical access to anything. If your computer is in a locked case, is that physically secure? In a lab that is always staffed? Behind a locked door? With a guard?

      For many situations, a computer with a locked case in a room that is staffed is considered "physically secure", as it's not likely that you'll break the physical security (lock on the case) without attracting the attention of the staff. Hell, even a computer in a staffed room in a case that has screws on it is fairly physically secure. The USB problem circumvents the physical security.

      Security is all about deterrent. My apartment has a dead bolt lock on the door. Does this mean it's impossible to break into my apartment? Of course not - it just makes it harder.

      Being able to break security on a locked computer with a USB drive is like leaving the key to your apartment under your door mat.

        Actually, security in this case is about doing a calculation of the worth of what it is you're protecting against the cost (be it a cost in terms of cash for access controls, or a cost in terms of user convience and system functionality) of the security. I've seen financial instituations who had all their workstations in a central computer room and just ran KVM terminals to each desk. The server room looked more like a vault. It was important to them to keep the workstations secure.

          Exactly. They might notice, but nobody's going to bat an eye. Frankly, most folks wouldn't bat an eye if they saw WinXP being rebooted either, not because it's necessary nearly as often but because people do it constantly anyway, because they've been conditioned that way.

      If it's a buffer overflow, then it's a software bug, not a problem with USB per se.

      If it's a vulnerability in a driver, then it doesn't matter if Microsoft didn't write the driver, if they ship it with Windows, they are responsible for it. There's no useful distinction between "Windows" and the drivers that ship as part of Windows.

    • So that means that it DOES run on linux? yay!...err Sorry, had to be done :)
    • The flaw is with drivers within windows, not the USB protocol. USB does its job, it says, "hey, I got this device on the server, its name is 8086:3429 and its a high speed device. Windows says, "okay, yeah, whatever" and starts accepting data. Unfortunately, drivers are an area where secure programming really hasn't caught on as well as it should, after all, their hardware never misbehaves and starts spewing out nonsense, right? ;3

    • When the system boots from a CD you don't need such complicated methods.
      But of course a locked-down system won't boot from CD.
      • BIOS? No problem, pop the reset jumper on the motherboard, and all the BIOS settings, including password and boot restrictions, are gone. When someone has physical access, they can get root/admin, if given the time. Our UNIX admin always maintains this philsophy, that anyone who has access to our servers can get root on them. So our security is not designed to make that impossible, but to make it hard enough and watched enough that we notice when someone tries it, and can go any confront them.
        • Same with workstations: when someone opens the case and/or resets the BIOS settings you will get an alert and can go after it.
          Usually the problem is not that someone can get access to the system. You only want to protect against doing that without being detected.

      • Correct. If NTFS is unencrypted, the computer is easy to compromise - you can just boot from a tool CD and modify/insert usernames/passwords.

      I don't need access to your system for that to work. I don't even have to know where it is. I have a usb key/mp3 player device which will let me reflash the firmware, so perhaps I could put the exploit in that way.

      That's true, but what about if someone has *restricted* physical access.

    • Unless the system doesn't boot from CD by default (like all the computers where I work) and you need a BIOS password to change the option (like all the computers where I work) and the case is locked so it isn't easy to reset the bios (like all the computeres where I work).

      So, how would you boot from CD now?
  • This is not true unless you let users install drivers themselves. Any reasonable administrator have allready blocked this in their default windows installation!
  • now i can convince my wife she can be a hacker too

    me: "yes honey....just plug this device over here.....yup..u just hacked the system...congrats"
    she: "this is l33t"
  • It seems obvious that this can affect any OS, and is due to the poor design of USB- If a device posts a number, then the system assumes it's such-and-such, and loads the driver. Which probably has bugs. So, how do We (that is Open Source system developers) deal with this?
    Of course 1. is to make sure that all drivers in our trees have no overflow bugs. Or any others, or course. This takes work, but we now know that it is needed. You cannot trust any info that a USB device gives us. Shoulda known.
    Of course, s
  • Lets see... You have physcial access to the machine and you can exploit it.. Wow. thats really news. *yawn*

    The uneven skills of driver programmers have left a legion of holes in software that ships with Windows and Linux, security experts say.

    Operating system vendors and hardware makers should commit more resources toward systematically auditing Windows and Linux device-driver code for flaws, security

    First and foremost, the guy says he has NOT notified Microsoft, but then goes on later to say:

    "I was really looking to them to address this issue, but Microsoft feels that this is a hardware issue and doesn't see it as a problem," he said.

    Which one is it, you told them or you didnt?

    Then he goes really REALLY far out of his way not to mention which driver is supposedly exploitable... is it a driver HE wrote?!

    I'm giving this 95% that its a driver HE wrote and installed to exploit ring 0 access, not an exp
  • While there is obviously an issue in that drivers, (particularly automatically loadeded ones such as Firewire and USB), have not undergone the security scrutiny that network software has, this is most certainly a PR article. There isn't a link to a technical description of the problem anyway, but the second half of the article is dedicated to vendor solutions. This article was instigated by a PR firm, not by normal media services. I wish I was going to blackhad though. After SANS I could only get work t
  • This reminds me of when I bought a new MIDI controller with USB, and plugged it into my Windows 2000 machine and it just simply BSOD'd...

    I couldn't believe it, just like that, BANG reset. Found it was a "known problem", so I followed the instructions on the M-Audio website, to the letter. Tried it again, still BSOD'd. To this day I can't use my USB MIDI controller in Windows 2000. Fortunately I use it mostly in Linux, where it works just fine.

    (For the record, it does work under Windows XP)
  • This would be even more effective than the jpg exploit. And how many of those vulnerable web cams use USB? Talk about hacking the planet.
  • A lot of you are missing the point. A "locked down" machine may not have physical access. There are circumstances where the machine itself IS locked down, by virtue of security cameras, monitoring equipment, or simply not having the physical box in the viscinity.

    However, this USB exploit lets anybody defeat all that with just plugging in a USB device. This should be fixed. It is serious IN SOME CIRCUMSTANCES.
