D-Link Tells Users To Trash Old VPN Routers Over Bug Too Dangerous To Identify (theregister.com) 126

Owners of older models of D-Link VPN routers are being told to retire and replace their devices following the disclosure of a serious remote code execution (RCE) vulnerability. From a report: Most of the details about the bug are being kept under wraps given the potential for wide exploitation. The vendor hasn't assigned it a CVE identifier or really said much about it at all other than that it's a buffer overflow bug that leads to unauthenticated RCE.

Unauthenticated RCE issues are essentially as bad as vulnerabilities get, and D-Link warned that if customers continued to use the affected products, the devices connected to them would also be put at risk. Previous bugs in similar products from other vendors have carried warnings that attackers could exploit them to install rootkits and use that persistent access to surveil an organization's web traffic, potentially stealing data such as credentials.

    • That's perfectly ethical. Revealing the details would give information to criminals who would use it to hack people who haven't replaced their devices yet. By keeping it as secret as possible they protect as many people as possible.

      Of course, they still have to disclose that the bug exists at all, which they did.

          Nope. "Security through obscurity" is when your initial system design fails to use good security practices, and you rely on "but nobody knows the protocol" or "nobody knows the port" or "nobody knows the password" as your design-level security implementation.

          In this case, an unintentional security bug was discovered after release. It is still responsible to issue a patch, but it is also responsible to keep the details a secret to protect users until they can get the patch.

          D-Link is refusing to issue a patch. I don't know all the details why so I can't judge. If the hardware was a recent purchase I would be pretty frustrated by that. But even still, keeping the details a secret just gives me more time to get the hardware replaced, so it is still the ethical response.

      • All that telling owners of affected routers to buy a new one is pretty close to perfectly guaranteed that they will buy some OTHER brand other than these shitheads products.

        • Well many on the list was EOL back in 2015 plus that they are giving you 20% discount on your new router. Now patches would ofc be preferred but then there is also the problem with "some OTHER brand" that you don't know if they would even disclose that their EOL models had a flaw to begin with, so switching vendor does not automatically improve your situation.
          • >Well many on the list was EOL back in 2015...

            The list, from the fine article:

            DSR-150N (EOL May 2024)

            DSR-150 (EOL May 2024)

            DSR-250 (EOL May 2024)

            DSR-500N (EOL September 2015)

            DSR-1000N (EOL October 2015)

            2 of the 6 routers are EOL'd in 2015. the other 4 were EOL'd !THIS YEAR!.

      • Revealing the details would give information to criminals

        They already did that by publicly announcing the existence of a bug. If you think that screaming from the rooftops "BIG EXPLOIT POSSIBLE ON X!", isn't going to attract criminals and have them expend resources to find and weaponize it, you're an idiot. (Especially when they've also announced that the only fix for BIG EXPLOIT is another hardware purchase.)

        Of course, they still have to disclose that the bug exists at all, which they did.

        And now the hackers are off to the races, with no fix in sight. Way to go.

        It would be even better if they released a fix. Telling people to replace their devices sure seems like bad business to me.

    • by lsllll ( 830002 )

      Lucky for us there are usually alternate OSS firmwares (for routers at least) to load and use manufacturers for what they're best at: factories and assembly lines.

      • Which is why I ALWAYS buy ONLY routers that can run one of the third party firmware out there.. My favorite is Freshtomato, odd name, great replacement for the, often braindead firmware that comes with routers.

        • If it doesn't run vanilla openwrt I don't mess with it. I might consider running a different firmware, but I know openwrt is quality.

          I like going to yard sales and whipping out my phone and checking their hw support db. I am working on getting enough nodes to build an emergency network for my tiny little town.

        • Tomato is an amazing piece of software. Even going back to the original, it was just so well designed as a UI. I don't use consumer stuff anymore; I've got an SMB router and AP's. But man, did that thing unlock so many possibilities of the hardware that the factory software just wouldn't do...

          I've got a Buffalo WHR-HP-G54 and probably 2-3 Asus models sitting in closets gathering dust that have it on board.

I don't use the VPN features, but do have two VLANs configured -- one for wired devices; one for wireless, off a DAP-2660 -- and both routers have worked great. I've been considering switching to a PC-based router running pfSense / OPNSense / IPFire (etc) but haven't been able to decide on which one and on what hardware.

        Probably depends on user expectations. That means you could have as little as 5 years of service (or more, if you bought it earlier). I regularly expect to, and do, run devices longer than just 5 years; especially things that are in the background and not fancy.

I come from a country where expected performance is codified into law, yet I'd struggle to be able to justify that a sub $100 plastic accessory should last more than 5 years, even though I have had ones last longer myself.

If you want to make a compelling argument to switch vendors then you'll need to find one which is appreciably different from D-Link. Synology is not, they also don't patch devices past EOL date.

        • NAS != VPN router. I'm happy to be proven wrong, show us a VPN router that was removed from sale prior to 2017 from Synology in current support and I will happily grab my megaphone and rave about them with you.

          Compare like products.

          • Well, the RT2600ac (I got the model number wrong) was their very first router released in 2017, and they still sell and support it to this day. The D-Link DSR-250N was released in 2020 and EOL'd four years later.

            Do you know of any other home router that has had seven years of support? Again, Synology is known for their support.

    • I prefer Mikrotik. Their devices are great, very customizable and have lots of features (some features run slow on some devices though) They also issue updates even for very old devices. I have a device made in 2007 (looking at the date codes on the chips) and the latest version of RouterOS still supports it. I had to recap it though, but, well, electrolytic capacitors do not last forever.

  • I recently found out that there are massive routers for cgNAT [ispreview.co.uk] because of multi trillion companies [github.com] refusing to use IPv6, so everyone's new shiny gigabit fiber connections all have to squeeze through a cgNAT tunnel for said websites. Then there are all the old routers, many of them 30 years old in many core networks of ISPs, facing large amounts of DDOS attacks because they refuse to patch their software because they'd rather spend the money on new AI GPUs instead fixing critical hardware. Just wait, there wi

    Limited Lifetime Warranty
    D-Link offers a Limited Lifetime Warranty on the DSR-150 VPN Router to further its commitment to product quality and long-term customer confidence.

  • so you could have bought a new one then and have to to 6 years warranty in the EU.
  • Its highly unlikely D-Link owns any of the ip in side of it. They bought the chips, licensed what ever Stack came with them and probably just slapped on their UI all over it.
    I doubt there is any thing they can really do.
     

  • When it comes to supporting products, D-Link are D-Bags.
  • It's very simple cars for many decades in most countries have had laws around them that govern health and safety. Routers do not. Organisations that employ routers may have health and safety laws but routers do not.

    - Thus a 20 year old car will receive a recall if a defect is found that can harm others.
    - A router manufacture will not be required to fix a flaw endangers the users of traffic that traverse it.
    - An organisation such as a hospital will be required to resolve a networking issue that has the pot

  • I trashed your router awhile ago, I'll stick with my MikroTik thanks.

  • If you keep buying stuff from D-Link, you deserve it
