Dozens of Netgear routers can easily be hacked — what to do right now [updated]
UPDATED with possibility of DNS rebinding attacks and news that Netgear has released hot fixes for two routers. This story was first published June eighteen, 2020.
At to the lowest degree 28, and very probable as many as 79, Netgear dwelling Wi-Fi router models are vulnerable to set on, both locally and mayhap over the net.
That's according to a new report by Arlington, Virginia-based cybersecurity house GRIMM (opens in new tab). Vietnamese security business firm VNPT ISC independently found the same flaw.

The problem, equally is then frequently the instance with home Wi-Fi routers, lies in the web server built into the router's firmware. The web server runs the web-based administrative interface that router owners log into with their administrative passwords.
The full lists of definitely afflicted and likely afflicted Netgear routers are at the end of this story. Tom'south Guide has reached out to Netgear for comment, and will update this story when we receive a reply.

How to protect your router from this set on
Unfortunately, Netgear has not yet provided firmware updates for these routers, despite existence told of the flaws in January by Tendency Micro's Zero Twenty-four hours Initiative (opens in new tab), which was acting on behalf of VNPT ISC.
It's likely we won't come across patches for any of these routers until the end of June. Some of these routers have reached cease-of-life and probably won't get patches at all.
If you ain ane of these routers, your best bet for the moment is to get into your authoritative interface (try https://192.168.one.i (opens in new tab) if you're connected to your router). Then select the Avant-garde manner or tab, if there is one, and try to find something that looks like "Web Services Management" or "Remote Direction."
You lot desire to make sure that remote management is turned off then that no ane tin can access your router's administrative settings from an external network, i.east. the Internet.
That won't quite solve the problem, equally anyone with access to your local network might yet be able to exploit the flaw. To prevent that, try to specify that only ane car on the local network tin can admission the administrative interface.
The danger with that final solution is that the designated authoritative machine must be specified by its IP address. Considering IP addresses tin can randomly (albeit infrequently) change on the local network, you could end upwards being locked out of authoritative admission, and would accept to factory-reset the router manually to regain that access.
UPDATE: Danger of DNS rebinding attacks
In that location'southward also a risk that malicious actors could use DNS rebinding attacks to exploit this flaw, even on Netgear routers whose administrative settings are locked downward, Lawrence Abrams at Bleeping Computer (opens in new tab) pointed out.
In a DNS rebinding attack, the attacker would have to command both a malicious website and a DNS server, ane of the and then-chosen "telephone books" of the internet.
If you were to land on the attacker'southward website, the assaulter could rapidly manipulate DNS settings then that a request for a particular website was changed to point to a device inside your domicile network. The website could then use JavaScript or other code on the website to set on that device -- in this case, a Netgear router.
The all-time mode to avoid DNS rebinding attacks might exist to alter your router's DNS settings to the free OpenDNS Home (opens in new tab) service, which will let y'all filter out those IP addresses reserved for local networks so that no DNS requests go to them. We've got a lot more on that here.
'1996 called, they desire their vulnerability back'
Both GRIMM's Adam Nichols and a VNPT ISC researcher identified only as "d4rkn3ss" discovered that they could apply a specific text string on two different models to put the routers into update style, bypassing the login process for the Netgear administrative interface .
From there, a input that was also long would trigger a buffer overflow — a very basic type of set on — that would give the attacker total power over the router and be able to run code on it.
"The entire update procedure can exist triggered without hallmark," Nichols wrote in a GitHub entry (opens in new tab), which too includes a proof-of-concept exploit. "Thus, our overflow in the update process is also able to be triggered without authentication."
Equally Nichols put information technology in his very detailed blog post (opens in new tab): "1996 called, they desire their vulnerability dorsum."
VNPT ISC's d4rkn3ss found this attack worked on a Netgear R6700 router, marketed nether the name Netgear Nighthawk AC1750 Smart WiFi Dual Ring Gigabit Router. (Netgear maddeningly obscures its model numbers in its marketing materials; "AC1750" is a Wi-Fi specification, not a model number.)
Nichols found that his exploit worked on a Netgear R7000 router, which looks almost exactly the same as the R6700, but is marketed as the Netgear Nighthawk AC1900 Smart WiFi Dual Ring Gigabit Router.
"The vulnerability been nowadays in the R7000 since information technology was released in 2013 (and earlier for other devices)," Nichols wrote in his GitHub posting.
Both models were among l-odd routers for which Netgear pushed out a ton of firmware security updates in early March of this year. Simply sadly, that was for an entirely different set of flaws.
Ironically, the Netgear R7000 was among the best, or perhaps 1 of the least terrible, of 28 home Wi-Fi routers analyzed in an independent study of router security in late 2018.
Afflicted Netgear models go back to 2007
Nosotros don't have much information about d4rkn3ss's research, but GRIMM's Nichols explained in his weblog post that he "was able to identify 79 different Netgear devices and 758 firmware images that included a vulnerable copy of the web server." (Routers volition frequently go through several firmware updates over their working lives.)
"I was able to create an exploit for each of the 758 vulnerable firmware images," he added, although attacks in theory don't necessarily piece of work in do.
And then, to make sure, Nichols "manually tested the exploit on 28 of the vulnerable devices to ensure that the identified gadgets worked equally expected."
His list includes well-nigh every router that Netgear has made since 2007, although few of Netgear'due south newest gaming models, and none of its Orbi mesh-router line, are on it.
Netgear routers are still pretty safety to employ, however
ZDI told Netgear of this flaw In early Jan. In early on May, Netgear requested an extension from ZDI of the non-disclosure window until June 15, despite the standard 90-day window having already passed. ZDI agreed to this, but then Netgear asked for some other extension until the terminate of June, to which ZDI did non agree.
Therefore, both ZDI and GRIMM released their findings now. (GRIMM, and so unaware of VNPT ISC's before discoveries, notified Netgear of the flaw in early on May.)
But that doesn't necessarily make Netgear routers unsafe to use. Netgear regularly issues firmware patches and security alerts, and makes information technology relatively piece of cake to install firmware updates. Many other well-known router brands do neither.
Just this week, D-Link told users of ane of its most popular routers to just chuck out the device and buy a new model, as it wouldn't be updating the machine any more despite known software flaws.
That'due south because the D-Link router is viii years old — just one year older than the Netgear R7000, which is still sold, supported and patched by Netgear.
Which Netgear routers are definitely vulnerable?
These 28 Netgear router models and their associated firmware versions have been proven to be vulnerable by Nichols. Some model numbers accept a "v2" or "v3" attached, because Netgear frequently makes hardware changes to a model during its production lifespan while keeping its model number and appearance intact.
UPDATE: Netgear has released "hot fixes" for the R6400v2 (opens in new tab) and the R6700v3 (opens in new tab), both of which should be updated to firmware version 1.0.four.92.
These are not permanent patches, but temporary workarounds, and Netgear includes the following warning on its support page (opens in new tab):
"While the hotfixes do fix the security vulnerabilities identified in a higher place, they could negatively affect the regular operation of your device. Though our pre-deployment testing process did not signal that these hotfixes would touch on device operability, nosotros e'er encourage our users to monitor their device closely after installing the firmware hotfix."
UPDATE: By Wednesday, June 24, Netgear had issued hot fixes for 15 more routers: the D6220, D6400, D7000v2, D8500, EX7000, R6900, R6900P, R7000, R7000P, R7100LG, R7850, R7900, R8000, R8500 and WNR3500v2. Links to all the patches can be found on the same Netgear back up page (opens in new tab).
You can effort downloading the hot-prepare directly from your router's administrative interface, but that didn't work for us. We had to download the hot-fix file to a PC, so upload the file to the router through the admin interface. Afterward that, everything went well.

Which Netgear routers are probable to be vulnerable?
Over on his GitHub business relationship, Nichols has a much longer listing (opens in new tab) of all 758 firmware versions, running on 79 router models, that he institute to be vulnerable at to the lowest degree in theory.
That's too long to add here, merely our friends at ZDNet distilled information technology down to router models, which we've adapted here by subtracting the definitely proven vulnerable models above.
Hither are 51 Netgear router models thought to be, but not notwithstanding proven, vulnerable.
