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."

      I'm not convinced. This is only a concern in cases where you're having technical problems, AND you somehow forgot your password. The danger of having a backdoor easily outweighs the potential benefits. Even with a special password generator from NetGear -- you're still talking security through obscurity. I want to set up my router, make sure it's secure, and forget about it! I don't want to keep checking online to see if you can download N3tg34r_PwG3n.exe yet... and you know it's going to show up eventually.

      Half the time you have any technical issues, the tech support is just going to tell you to do a hard reset anyway....

      Even if they gave you one of those paperclip-hole style buttons that would reset all your passwords to your device's serial number (or to enable some other backdoor), this would still be dangerous in a lot of situations. Suppose you're running an internet cafe -- you can't always trust the people sitting around your router!

      Either way, I don't think this backdoor was installed for tech support reasons -- it doesn't even seem to have been installed by NetGear themselves. Hopefully some more details will come out soon... and hopefully some heads will roll.

      It's funny; I just read that new story by the AdTI guy explaining how Linux wasn't safe to use because it depended on "trust". Hah! How nice for the corporate world to step forward and show that *they* can be trusted.

      I'm always astounded when others are astounded by the existence of back doors in things. Pretty much anything that takes a password has a backdoor in it. Phone systems, voicemail systems, even those telephone entry systems on apartment buildings; all got back doors. Tech support is hard enough already without having to deal with unknown passwords. Some are better than others, though. Sentex telephone entry systems have back door passwords that are a hash of the unit's serial number, and only Sentex tech support has access to the program that generates them. Not that one usually needs the backdoor; most Sentex units I see still use the factory password "000000"...
