D-Link Patches Critical Vulnerability In Older Routers 54

Posted by samzenpus from the protect-ya-neck dept.
An anonymous reader writes "D-Link has released firmware patches for a number of its older routers sporting a critical authentication security bypass vulnerability discovered in October. The flaw was discovered and its exploitability proved with a PoC by Tactical Network Solutions' security researcher Craig Heffner. D-Link confirmed the existence of the problem a few weeks later."

      Back in the day, a lot of consumer routers and access points* came out of the box with remote management enabled. It was something that only we geeks knew how to turn off. More importantly, knew why to turn off, and if left on, we had good reason for so doing. With other than the default password. Which leaves the other 99.42% of buyers with it still wide open.

      I remember at least one Linksys and one D-Link out of the half-dozen or so I went through in the late-90's through mid-2000's that defaulted to remot

  • It's good that the patch is available, but what percentage do you actually think will get fixed? Your average user isn't even going to know how to apply a firmware update much less be aware that they have a vulnerable router and need to update it.

    • The average user uses the router provided by their ISP; the average ISP provides a wireless connection as well as a wire to the customer. Most of them don't ever buy another router.

      Of those who do, a substantial percentage are the type to know what a firmware update is, and why you would want one.

      Of those who aren't, I suspect (but have no proof) that a substantial percentage are the type to replace their router periodically anyway, to keep up with their new devices. They go to the store and say that they'r

          What you're missing is knowledge of the topic being discussed. Virtually every broadband internet connection is implemented in this fashion. Whether you get the crappy little DSL modem from ATT or the Xfinity modem from Comcast, you're getting a really crap router with a really crap modem built in; in the former case it's a DSL modem, and in the latter a DOCSIS cable modem. Usually it's no more than 802.11g, but that's adequate for most purposes for users with few wireless devices. The box is installed near

          • I know of no ISP in the last 5 years that doesn't offer routers. Easy money every month. To not offer them is leaving a lot of cash on the table - these companies know better at this point. I even worked for a local (rural) telecom about 4 years ago, and we offered them then.

But if you investigate individual markets you will likely find even many of the large corporations have coverage gaps for leasing certain equipment. And for some reason wifi routers seem to be one of those pieces of equipment.

              Thanks for the intelligent response though. I definitely agree (assuming you are implying this) that in today's day of age most ISPs should take advantage of that easy money. After all, 5 bucks a month on a $40-60 ite

            Comcast would happily rent me one of their routers, and I'm beginning to see their wireless routers litter the RF landscape near my house.

            Charter Cable would also enable the wireless features on the router I have through them. They apparently stock and install one cable modem/wire+wireless router and then enable what you pay for.

            Personally, I bought the cable modem for my Comcast connection, and run a D-Link wire-only router behind it for routing. And then whatever wireless router I feel like behind that

        • What am I missing here? Don't know of any ISP that supplies routers.

          Maybe this is a regional thing, round here pretty much every ISP either gives you a router or tries to sell you one when you sign up for service. Some even insist on you using it.

          And even replacing an older router with a faster one won't do a thing for speed. (unless it's bad) Most will handle 10 times the speed that the modem will.

          It depends, if you are on ADSL or a slow cable package then it's not going to make much difference.

          As you move up to high end cable or FTTC+VDSL services then older routers can certainly become a bottleneck and if you move up to FTTH services then you will allmost certainly need a new router to avoid bottlenecking the connection.

      This has broader applicability as well. No matter how much software people may wish otherwise, people treat their hardware like a black box and it makes no sense to them for it to be changing after the fact.

      Late in 2009 I had the opportunity to setup a brand new D-Link DAP 1522 access point and I discovered a telnet interface with hardcoded credentials in the firmware. I have never disclosed the vulnerability to the vendor or publicly. Four years later the issue is still there on most D-Link SOHO network devices.

      (emphasis mine)

      I don't doubt the existence of this vulnerability, just the motives and timing behind disclosing publicly on this blog.
