NetGear Also Has Remote Access Wide Open

Glenn Fleishman writes "On the heels of Linksys's WRT54G problem of not allowing remote access to be disabled in certain cases and firmware, BugTraq published this report that NetGear's WG602 access point has a hidden password that provides remote and local administrative control. Unlike Linksys's, where turning the firewall on (which is on by default, but a researcher found new units in which it was off when taken out of the box), the NetGear hole cannot be disabled. The backdoor seems to have been created by the vendor that packaged the device for NetGear."

      If 11Mbps is sufficient for your needs, you could by a 802.11b wireless card that uses the Prism 2.5 chipset. This chipset can function in hostAP mode. At home I use Netgear MA311 in an older Dell functioning as my wireless access point, internet gateway and firewall. Instead of WEP, I use IPSec, and only authorized IPSec traffic is allowed (and thus no leaching from my Kazaa loving neighbour).

      You might need to flash the firmware, though, which you can find here.

      If you want a secure, easy and hassle free gateway, just install OpenBSD.

    "The only way to clear the BIOS password is with a Master Reset Password provided by Dell for that Model No. and they will not give you the master unless you can give them the name. address and telephone of the registered owner. However the password is universal for all laps with the same model no., so if you know someone who is a registered owner, you can call Dell and get the master."

    I know this is a huge problem for the general public, but for those of us with a linux machine, do what I do and save yourself some trouble: put two network cards in the linux machine. Connect one to the internet and the other to your wireless router's normal ethernet ports (don't use the port that is supposed to be for the internet). Then, just set up your linux firewall/NAT, and you get all the benefits of wireless and a wired hub on the inside, with a linux machine doing the routing/firewalling for security from the outside. Since the router isn't on the net, no one can even touch it.

      Hrmmmm. I like it when others tell me what I said.

      No, I did not issue a statement admitting it was a false report. I said that a critical element did not show up in testing of newly purchased equipment.

      And I am not sure how I feel about Mr. Seltzer's article. Especially his statement about trust. It is obvious that we should trust him over others because he is the author of the "Official" book on LinkSys. I do not, however, think that we should dismiss, or not trust, anything anyone has to say about security, regardless of stature. True, my announcement was not confirmed, and the more responsible in the Internet news community did indeed hold off on their reports while responses and discussions continued. Bravo.

      LinkSys has "told" us by proxy of Mr. Seltzer that the units I got with the odd behaviors were customer returns. Well, I cannot speak for what LinkSys says -- they certainly did not say that to me. I do say that is pure conjecture, on both my and LinkSys' part, but it does make for a reasonable assumption concerning the three units used in later testing.

      Just for information, there is no comment from LinkSys on this issue on its press release page http://www.linksys.com/press/press.asp , nor from Cisco http://newsroom.cisco.com/dlls/index.html

      Even so, I still stand firmly by my original findings. Two older units *did* do this, even after a factory reset. Bad hardware? Pre-release firmware? Who knows. I saw what I saw. But it does go to prove one very important point: we should not be complacent about our perception of security. If you install Internet-facing equipment for clients, you are providing a great service to everyone if you port-scan the device. When you purchase Internet equipment, check the configurations and make sure it matches up to what you expect. Do not take your security for granted.

      As an aside, Larry Seltzer, regardless of his credibility, is another journalist who has never contacted me for clarification or expanded information.
