Wi-Fi Protected Setup PIN brute force vulnerability

Filed under: advisories — Stefan @ 3:00 am

A few weeks ago I decided to take a look at the Wi-Fi Protected Setup (WPS) technology. I noticed a few really bad design decisions which enable an efficient brute force attack, thus effectively breaking the security of pretty much all WPS-enabled Wi-Fi routers. As all of the more recent router models come with WPS enabled by default, this affects millions of devices worldwide.

I reported this vulnerability to CERT/CC and provided them with a list of (confirmed) affected vendors. CERT/CC has assigned VU#723755 to this issue.
To my knowledge none of the vendors have reacted and released firmware with mitigations in place.

Detailed information about this vulnerability can be found in this paper: Brute forcing Wi-Fi Protected Setup – Please keep in mind that the devices mentioned there are just a tiny subset of the affected devices.

I would like to thank the guys at CERT for coordinating this vulnerability.

Update (12/29/2011 – 20:15 CET)
As you probably already know, this vulnerability was independently discovered by Craig Heffner (/dev/ttyS0, Tactical Network Solutions) as well – I was just the one who reported the vulnerability and released information about it first. Craig and his team have now released their tool “Reaver” over at Google Code.

My PoC Brute Force Tool can be found here. It’s a bit faster than Reaver, but will not work with all Wi-Fi adapters.

Update (12/31/2011 – 14:25 CET)

Update (04/01/2012 – 17:45 CET)
Tactical Network Solutions has decided to release the code for the commercial version of Reaver. You might want to check it out.

  1. I only just bought a new Netgear router yesterday. I had my suspicions that this was insecure. Looking forward to giving the tools a go.

    • Netgear has a so called Push´N Connect Button on router devices. The WPS function is only working for a short time. So they are probably safe!? The vulnerability needs some time for brute forcing.

      • not necessarily: I’m currently testing a WND3700, this device has push connect, but it also seems to support the PIN method. Sorry.

  2. “will be released once I get around to cleaning up the code”

    For most people this means “never”. I’d rather get a chunk of dirty code and try to figure it out than have to try to re-implement this attack from scratch.

    Please post your messy broken code.

    • Seconded. In fact, since it’s such an important part of the paper, arguably the code “not being ready” means the paper isn’t, either. But even if you disagree with that, then this still leaves people shorthanded verifying a) their devices are vulnerable and b) they’ve successfully mitigated the problem by turning off the feature. Wouldn’t be the first time shoddy firmware says one thing but does another. As such, the only remedy now is to take every last AP offline until someone gets around to releasing a tool to check mitigation.

  3. If the code is not ready, in the interim it would at least be useful to have a way to confirm whether a particular access point implements the “External Registrar” method of WPS. Looking at several of the ones in my possession, it was unclear which ones are affected. One device has the Push Button Connect physical button but it does nothing and manufacturer documentation says WPS is not implemented and is reserved for future use. Another device has no physical button but implements the “Internal Registrar” method of WPS through the network admin interface, and may also implement the External Registrar method, but I have no way to easily confirm that.

    • I had to change line 480 code to make it partially run on Nokia N900 with Python 2.5:

      elif (self.rcved.is_set() is False): to elif (self.rcved.set() is False):

      Now I get the same problem as other posts with being stuck at PIN 00000 (even after updating to python-scapy 2.2.0)

    • I tried running your code but seems not to be working on my system. I’m running backtrack 5 with an iwi3945 card. There some clock skew on install. when I try to run the script it says it can’t associate and reports the correct essid. The router is a linksys e1000 with wps on.

        Comment by hrmmm — December 29, 2011 @ 6:15 am

      • This is probably an issue with the wireless driver. I’ve only tested it against Atheros ath9k drivers and the Realtek drivers for the Alpha cards, so both of those work fine, but others may not work. Switching to something like lorcon for packet injection will probably fix these types of issues…

        Comment by Craig — December 29, 2011 @ 11:04 am

      • The latest changes to 80211.c have the code working on my iwi3945 card! Brilliant!

      • I have also encountered the linksys WPS functionality failure described in the pdf. For me, it occured after about 200 tries. The model of router is a Linksys e1000 v1 2.1 firmware 2.0.00

        Comment by nick — December 29, 2011 @ 4:13 pm

  11. The other mitigation that should be recommended is to never send EAP-NACK in response to the first half of the PIN. Always send the second half of the negotiation, and send EAP-NACK in response to the second half of the PIN if either half was incorrect. That brings the required number of brute force attempts back up to 10^7, which means it will take over 150 days to search the entire space with your assumed attack time of 1.3 seconds per attack, even without any lock down (or 75 days, on average, to find the PIN).

    Rather than a complete lock down after a few failed attempts, I think it would be better to introduce a delay after receiving a few (5 or 10) failed attempts. A 30-second delay per failed attempt requires 1,811 days (4.9 years) on average to find the PIN, 60 seconds requires 3,547 days (9.7 years). This has the advantage that a legitimate client with the correct PIN can still authenticate, even if the device is under a brute force attack. A 30-second delay strikes me as a good compromise between resistance to brute force attacks and responding to legitimate requests.

    If it’s difficult for the attacker to spoof their MAC address, then a per-MAC-address complete lock down is even better. It can provide a much longer average time to find the PIN (a 60-minute lock down after 5 failed attempts leads to a 114-year average time to find the PIN) while still allowing legitimate clients with a different MAC address to authenticate. But if the attacker can send each request with a different MAC address they can bypass the lock down.

    (All of these average times to find the PIN assume the first countermeasure described above is applied, of course.)

    • MAC spoofing is trivial — so trivial that it should never be used as the basis for security. A network card’s MAC address can be changed in microseconds, and there are about 281,474,976,711,000 addresses to choose from.

    • The no NACK idea is good – thanks … I’ll add this to add this to the WPS 2.1 testplan.

      The current specification and testplans recommend delays and lockouts – it’s just that vendors were lazy and only met the minimum required for certification testing.

      Comment by Paul — January 6, 2012 @ 11:58 pm | Reply

      • Some associates pointed out that never sending a NACK does NOT help. If you send a correct next message it exposes the second half PIN. If you send the wrong second half – it’s detectable and just adds a little more work beyond the current attack.

        Comment by Paul — January 9, 2012 @ 11:15 pm

  12. Are you sure that all of these routers leave WPS on all the time? WPS is only supposed to be “on” when the person presses the physical or virtual button on the router to start a WPS transaction. What’s supposed to happen is the router only does WPS for a certain window period after the button is pressed on it. It’s not supposed to be doing WPS all the time.

    Comment by Phil Kearney (@pfk3) — December 29, 2011 @ 12:41 am | Reply

    • Yes I am sure that the PIN – External Registrar option does work all the time. WPS supports different configuration options and only one involves a physical button.

      Comment by Stefan — December 29, 2011 @ 8:04 am | Reply

  13. Just turn wps off (i guess for some routers don’t hit the button, hated that with linksys routers of old in work settings…someone would eventually hit the button which was the linksys logo that wouldn’t make you think it was a button when someone just needed to move it out of the way because there was shitty locations for wireless routers). I have no idea where it’s handy. The easy-to-use-encryption-for-dumb-people fails.

    Instead of typing in different pins for every device, i always though it was easier to name a wireless network and give it a password with any of the encryption choices offered (just not wps).

  14. If an AP supports external PIN registration for an unlimited time, that would be a problem regardless of an efficient brute-force attack.

    However, the claim that this will affect all WPS routers is overreaching. Even in your limited tests you hit one that malfunctioned before letting you in. I know Apple APs don’t support adding clients without taking action on the AP, so the “all of the more recent router models come with WPS” claim also goes too far. You should clean that up.

    • I’m afraid this is fairly accurate. Fellow researcher Craig Heffner agrees: “roughly 95% of modern consumer-grade access points ship with WPS enabled by default” (from http://www.tacnetsol.com/products/). The Apple devices are (as always) a bit special because they do only seem to support PIN – Internal Registrar.

  19. No doubt the various hardware vendors will take a long time to rollout any firmware update. What really worries me is that some only seem to keep updating firmware for a year or two after release and then completely stop, which leaves a lot of kit vulnerable to old exploits that could and should be easily fixed.

  35. There’s a minor thinko in the complexity calculations in your paper:

    > This form of authentication dramatically decreases the maximum possible authentication attempts
    needed from 10^8 (=100.000.000) to 10^4 + 10^4 (=20.000).
    > As the 8th digit of the PIN is always a checksum of digit one to digit seven, there are at most 10^4 + 10^3 (=11.000) attempts needed to find the correct PIN.

    You forgot that “the 8th digit of the PIN is always a checksum” applies also to the raw brute force combination calculations for the whole PIN, not just the calculations for forcing the two parts of the PIN separately, so the maximum possible authentication attempts figure should only have been 10^7, not 10^8.

  60. Great work and easy to understand paper. What about (in Germany wide spread) routers from AVM (Fritz!Box). Did anyone check them?

    Comment by Matthias — December 30, 2011 @ 12:01 pm | Reply

  61. For all those that are stuck at the timeout, I noticed this, line 481:
    if x.haslayer(Dot11) and x[Dot11].addr1 == self.client_mac and x[Dot11].addr3 == self.bssid:
    Basically that checks if the incoming packet is for us, but it does a strict case sensitive match (incoming is in lower chars)

    So just use lower case MAC id’s.

    Comment by vlad — December 30, 2011 @ 12:08 pm | Reply

    • Or just modify lines 607 and 608 to:
      wps.client_mac = options.client_mac.lower()
      wps.bssid = options.bssid.lower()

      • @ianchov you have to install a new version of Scapy (2.2.0)!

        Comment by Stefan — December 30, 2011 @ 12:51 pm

      • Great!

        Thanks Stefan.

        Scappy latest seems to fix both issues 🙂

        Thanks

    • Stefan: it’s crashing my test router, a d-link DIR-635. Literally crashing it and self-rebooting every 10 or so attempts, but it does seem it work (it found the first half of the pin; instructed it using -p to a close value)
      Other routers that I have tested are a bit far away for real-time testing, stuck at M4 usually.

      Great tool btw!

      • Nice to hear that! Unfortunately WPS implementations are not as stable as they should be, you could try to add a sleep(1) or so between each attempt.

        Comment by Stefan — December 30, 2011 @ 12:55 pm

  62. Sorry if this is a noob question but the client has to be a client currently associated with the target AP? Yes?

    cheers

  126. Hi! Thanks for the tool. I tried it and it doesn’t work, logs are below. As for my config, I’m using the default version of Backtrack 5 R1 with an Intel 5100 card inside a laptop. The driver might be iwlagn but I wouldn’t quote me on that, I’m yet to check in BT 5. OS is running from Live USB.
    Finally, I *think* I installed Scapy 2.2.0 properly; only thing I installed. I’m not used to Ubuntu/Backtrack so here’s what I did and you decide if it’s valid: I downloaded the .zip file using Windows, then copied it onto Backtrack’s desktop after a reboot to switch OS, then double clicked the .zip which seemed to do the install automagically. (and indeed I see Scapy files in usr/local/somedirectories, though I’m couldn’t check if it’s really v2.2.0)

    BSSID is on channel 6 and WPS is enabled with PIN set to 00010009, although this AP might be immune to external PIN connection. Commands:
    airmon-ng start wlan0
    airodump-ng –channel 6 mon0
    ./wpscrack.py –iface mon0 –client 00:99:88:77:66:55 –bssid 11:22:33:44:55:66 –ssid SomeSSID -v

    Logs:

    • Probably weak signal or the AP doesn’t support WPS.

      Comment by Twilight.zero — January 7, 2012 @ 12:12 am | Reply

      • Before running the script you need to set your wireless device to ‘monitor’ mode. In Linux, this can be achieved using ‘airmon-ng’, a utility included with aircrack-ng when installed on Ubuntu.

        $ airmon-ng start [wireless interface name, like ‘wlan0’] [channel number, e.g. ‘6’]
        # airmon-ng start wlan0 6

        If you’re using a mac80211 driver, this will create a new device called ‘mon0’ which is in monitor mode. If you’re using another driver, it will set ‘wlan0’ to monitor mode. Once this is done, you can do the following from the README:

        iwconfig mon0 channel X
        ./wpscrack.py –iface mon0 –client 94:0c:6d:88:00:00 –bssid f4:ec:38:cf:00:00 –ssid testap -v

        Of course, substitute your own values instead of the ones provided above. Use the –help flag to see an explanation of each.

  149. Heya, I was justing wondering if SecureEasySetup is in trouble too?, as I’ve read it’s just a different name for WPS.

    My router (WRT54G v7.0) only has the option to Enable/Disable SecureEasySetup , no mention of PINs.

    I have tried Reaver which couldn’t associate with my AP, but could on others, and its discovery tool “walsh” doesn’t list my router, but that could of course just be because it’s not calling its self WPS, so isn’t logged.

  157. No lie – it looks like someone pointed-out most of this design flaw back in 2009, but (a) he didn’t run it to ground, and (b) nobody noticed. True, he ranted about some other stuff, but aside from noting the shortness of the PIN and the inability to change it (or disable WPS on some devices), the basic flaw is there.

    • You need to specify also the -client, -ssid arguments on the input loine (hence the message about arguments). The IPv6 message is issued by scapy, just ignore thatN since we are working over IPv4.

Also the firmware is propietary and because of 2MB of flash doesn’t support dd-wrt. So in other words if you have a WRT120N router like me you are in big trouble.

    GAME OVER!

  197. I was using reaver and wpscrack for quite a while now. While reaver does a good job in general, I’m a big fan of python and prefer wpscrack as it’s easier to modify and extend. As the further developement seems to be stopped, I uploaded it at github now ( https://github.com/ml31415/wpscrack ) and started to add some tweaks. Anyone who would like to help improving it, feel warmly invited.

  206. While there are stories out there of people who started businesses with a dollar and a prayer,
    their success is either unusual (which is why they became
    a big story) or it took much longer than it should
    have. I have seen people use their credit cards to fund a
    business, and this can be done; but the interest you pay on the initial money means
    that you are paying up to three times to
    start your business. If you start out on your own you
    would need to figure everything out alone and you would not have anyone
    to turn to for help.
