Firefox 2.0 Password Manager Bug Exposes Passwords 315

Posted by kdawson from the be-careful-out-there dept.
zbuffered writes, "Today, Mozilla made public bug #360493, which exposes Firefox's Password Manager on many public sites. The flaw derives from Firefox's willingness to supply the username and password stored on one page on a domain to another page on a domain. For example, username/password input tags on a Myspace user's site will be unhelpfully propagated with the visitor's Myspace.com credentials. It was first discovered in the wild by Netcraft on Oct. 27. As this proof-of-concept illustrates, because the username/password fields need not be visible on the page, your password can be stolen in an almost completely transparent fashion. Stopgap solutions include avoiding using Password Manager and the Master Password Timeout Firefox extension, which will at least cause a prompt before the fields are filled. However, in the original case detailed in the bug report, the phish mimicked the login.myspace.com site almost perfectly, causing many users to believe they needed to log in. A description of this new type of attack, dubbed the Reverse Cross-Site Request (RCSR) vulnerability, is available from the bug's original author."

    Now that its 2006, can we now use a better form of "authentication" than a few ascii characters?

    Every website wants you to have a password. You know, for important stuff like making a purchase because you use a password for a purchase at a brick and mortar store, right?

    Well, since its a good practice to use unique passwords, and users get forgetful, then they use the web browser tool to store their passwords, then they forget their passwords, and when they use another computer or update their existing one, their tool does not work, and if it does work, then the browser gives away your passwords.

    I don't use a password to get into my home, I don't start my car with a password, I don't use a password to get into my work. In fact, I don't even have a key for my work, server room, nothing (RFID). But all day at work, these programs continually ask for my password to the point that I dont consider my password secure because I have to change it, and use it so much, I'm desensisized (sp?) and say who cares?

Hell, it doesn't matter how good your encryption is, all it takes is a videocamera pointed at your keyboard.

      I strongly hope so. My recommendation would be public key authentication, the way SSH can do it. You'd need a private key (possibly on a crypto card, but a thumbdrive or floppy or whatever works fine) and a password for that. You authenticate to the key when launching your encryption agent, then any website that wants to verify who you are contacts your agent and does the authentication there.

      Infinitely more secure than our current password system, a lot more convenient (think Microsoft Passport's bragged about convenience, except none of your data is stored on a central server), and all around the BetterWay(tm). The main downside if when roaming to another machine if you don't have your key, you don't have access. This can be addressed with either being able to fall back on a password (removing a lot of the security), or some means of authenticating to your home computer.

      You could also add some sort of spec for feeding VCard info into the agent so that sites could use it to do a sort of shared profile feature, where you'd authorize a site to receive certain info and save you a lot of time filling stuff out.

      Unfortunately this is just yet another thing on the list of "tech the way I think it should be", not anything on anyones todo lists.

        USB flash drives are becoming really popular. Some standard location on a flash drive to place a private/public key pair, would mean you could provide credentials just by sitting down at a PC and plugging in your flash drive. Having said that, then means losing the drive is... really, really bad. Also means a virus infected system could grab your keys, but then that's more or less a risk with password

      Passwords work great for me. I, however, use them with care.

      Any site that uses financial information (my bank, eBay, PayPal, Amazon, or whatever I'm buying, my own servers, etc.) doesn't get the password stored in any form of password manager. On the other hand, inconsequential services like news sites, LUG sites, aquarium discussion groups and the like may have the passwords stored.

      If you have 50-100 passwords at various sites, established over years, there's really a shortage of other good options. You can go the old-school route and just write them all down on a pad of paper, or the slightly more sophisticated route and put them in a text file or encrypted database on your local machine, but that doesn't help you when you want to log into a site from another machine.

      It's not your own browser to worry about. It's others browsers. My roommate decided to borrow my machine and was stupid enough to have Firefox remember his password on my machine to the main school portal. No biggie, except that the 'reveal all passwords' button exists (and, last I checked, required no authentication to use).

      Of course, the truly telling moment was when I found out how lame his password is. Not that I'd expect anything different from someone dumb enough to store their password on someone else's computer in the first place.

      So, in other words, passwords continue to be useless for people dumb enough to leave them lying around. I've used the same password for years and it's by no means secure (only just a bit more secure than using my first name) but it's never been an issue for me. The only time I've been concerned is when websites force me to come up with something that fits their requirements, because that means that I do end up writing it down somewhere. The sooner webmasters realize that setting specific requirements for passwords makes them less secure (my bank requires an alphanumeric PW 6-8 letters long with mixed case - that massively narrows down a brute force attack), the better. In the end, most of it comes down to user stupidity, so we might as well not limit the complexity of good users or force them to use something too obscure to remember (or, worse, say 'write this down in a place you can easily access').

I noticed back on 1.5 that every time I put my laptop into standby with FF running and then woke it up that FF would slowly increase it's memory consumption to about 30% more than what it was before being put into standby. Ie, if it was 100MB when it went to standby it would be around 130MB after waking the laptop, switching focus to FF, and clicking through my opened tabs. In FF 2.0 I have to literally shutdown FF every day or two or FF will easily consume upwards of 500MB of my RAM. I usually have about a dozen windows open and in each window I have 5-15 tabs. That's a fair bit but it didn't cause me much grief in v1.5.

    It also took me a while to figure out how to remove the close button from each tab [wordpress.com]. The tab scrolling "feature" was also a point of great annoyance that took up more of my time to find a fix [lifehacker.com].

        Yes, but that's not a problem because they aren't on a domain where you have a saved password. The problem here is that random people can upload content to, say, myspace.com, and if you have a password for myspace.com, your browser will automatically fill their form in. When an attacker uploads something to attacker.example.com, you aren't going to care because you don't have a saved password for attacker.

    • I agree that the bug is first and foremost due to myspace, but the Firefox Password Manager certainly doesn't help. It should be clever enough to not fill out that particular form, as it does not direct to the myspace domain. Hopefully this will be fixed as soon as possible; seems to me that it shouldn't be such a huge fix.

      But back to myspace. This fake form is extremely insidious, and looks exactly like the real thing. Only a viewing of the source HTML will reveal that there's something fishy. Allowing us

    There is a neat little piece of javascript at http://www.xs4all.nl/~jlpoutre/BoT/Javascript/Pass wordComposer/ [xs4all.nl] that lets you just think up a master password in your head and then use this applet to automatically generate a site-specific, unique hash and fill in the password field automatically. This way you can remember the passwords easily, you never have to save them or write them down. And if one site gets compromised, that password (the hash) won't work with any other site. The drawback is that if you don't have this piece of javascript then you can't get into your sites.

      It's a simple algorithm which you don't need to keep secret. Also, you can write down the made-up user/domain/iteration triplets. All you need to keep secure is the master password. Thanks to the iteration, you can lose a generated password without affecting the secrecy of your master password or all the

    I for one only use the browsers store password feature for the most trivial of sites. For more important sites, I use Password Safe [sourceforge.net]. The program and the database fit easily on a thumb drive, and requires a master password to access. It has a user configurable time out, and a double click on an account copies the data to the clipboard for later use, allowing you to foil keyboard based sniffers.

    I have two types of passwords: The ones for fluff sites, like Slashdot, Wikipedia, hotmail (a.k.a. Spam box), and so forth, which usually get 1 of 2 passwords. Then for banks and credit cards and what have you, I use real passwords with different ones for each site.

    I could care less if someone hacks my Slashdot account or my wikipedia account. The worst thing they can do is vandalize under my name. And as for hotmail, they can have my spam. And were I to have a myspace account, I could care less if someone got that too.

    Fortunately, my bank and credit card companies don't allow others to create their own pages, so I'm not too concerned. I suspect this will get fixed long before it becomes a concern for me.

    It is not a bug with firefox, it is a bug with myspace.
    I doubt you will find many places other than myspace where this "bug" will be exploited. Why? Because most sites that host user generated content are responsible enough to remove the users ability to post potentially-malicious markup language on the site. These sites strip almost all (if not all) markup and only allow a small handful of decoration tags like BOLD. (Slashdot is a perfect example of allowed html markup)

    The problem is that the code on myspace is shoddy at best, and the fact that users can put any kind of html on their myspace page was an accidental result of such. Then when users figured out they could customize their page with css and other markup code they were happy, and so myspace left it in.
    Nowadays everyone is so used to myspace letting them customize their page (in a shitty hack sort of way) that if they were to take that aspect away I think myspace would die in a month (I know a lot of girls who only go on myspace so that they can upgrade their page and make it look better by customizing it) so they are not likely to ditch this "feature" of their site.
