HTML Frames Considered Harmful 104

Posted by timothy from the also-ugly dept.
DLWormwood writes "Secunia has recently issued yet another advisory about web browser vulnerabilities, this time concerning the use of frames in web pages. Originally discovered to be in Internet Explorer, the security experts apparently worked overtime just to make sure the same "flaw" is found in just about every other browser out there. Doesn't this notice simply complain about a specified design feature of frames? (Note their official "advice": "Do not visit or follow links from untrusted websites.")"

    Since when was this news?!

    Frames are evil. Frames supposedly make the webdesigners job easier, but they cause an increased maintenance overhead. Frames supposedly creates a better interface to a website for the end-user, but they cause severe usability problems.

    Its common to see frames abused by newbies in implementing a left-hand menu and top banner layout with the mistaken belief its easier to maintain and makes downloading quicker. There are numerous problems this implementation raises typically related to the paradox it creates.

    To make-up for the usability deficiencies, many framed websites use some client-side techniques which cause further maintenance nightmares. There is a definite usability versus maintenance trade-off with frames, which make it a difficult technology to manage well. The alternatives available have none of these drawbacks, thus frames are a sub-optimal, and typically backward solution.

    Most of this "usability"-hacking of framed websites results in a complete dependancy on Javascript - another evil. Considering the on-going problems related to Windows lax security model (in the OS, Outlook and Internet Explorer) and the exponential growth of scripted worms and viruses (Melissa, Love Bug, Kornikova, SirCam, Code Red, Code Red II, Code Blue, Nimda), this convinces a greater number of surfers switching off Javascript entirely, which in turn causes a framed and scripted site to die a rather horrible death in the browser.

      the mistaken belief its easier to maintain and makes downloading quicker.
      It does make downloading successive pages quicker, but I don't know anybody at 14.4K, so it doesn't make anywhere near the difference that it used to. It helps download speed, if you have rollover image based navigation (really a mistake, but sometimes you don't have a choice). Also, before the ubiquiness of the Application server it was either use JavaScript Objects kept in a hidden frame (or what was later called a 'pop-under') or roll you own CGI session mgmt.

      However, you are right bout the need for usuability hacks with frames, just getting the back button to work right is a real pain. But, I disagree about JavaScript being 'Evil', it's a tool which is particularly well suited for client side actions. I have used JavaScript recently to re-order a list rather than redoing the query, it's much faster than any of the alternatives. If you want to surf the net with JavaScipt turned off, that's your business. Now I avoid frames, unless I am told that is how it will be, but JavaScript is still very useful, especially combined with CSS (aka DHTML)

      The "lax" windows security model and the viruses you mention may be issues, but they have nothing to do with this issue. It's like saying: "Becuase of the war in Iraq, and the growth of fungus, You should only have salad at McDonalds', because it's better for you, QED."

      I have to agree that in common websites, frames are quite useless and ugly. All they really do is make nagivation a hell, but there are situations where frames are useful. I work on internally-used applications which sometimes have a web interface, and the users actually asked to have frames available in some cases. Frames can fill the gap between the usability of a standalone application and flexibility of the web.

      It might seem useless, but the simple fact that frames can be resized does suit most needs. Users can decide which section of the content is most useful to them. A common usage is when the users actually need to compare documents. Having both side by side can be nice.

      Just imagine Java's documentation without the frameset, it would really be a pain to search in. The class list is very long to load, and I'm quite happy they didn't simply include it in all pages.

      Frames are not evil, neither is JavaScript, it just depends on how it's used. Using frames for a menu is not a good thing, and using frames for a banner is simply worst. Those kind of usage really gave frames a bad reputation because they simply reduce the amount of usable space on the monitor. JavaScript used for pop-ups or ugly 'eye-candy' stuff really also is an error, but JavaScript can enable some real dynamism in a form and actually allow to save a lot of time in the processing. Isn't filling country, state and city automatically nice when a user enters a zip code?

      There used to be problems with JavaScript and browser compatibility, but it's not that bad anymore. Of course, IE simply won't support everything, but there are always workarounds.

      Really, those things are only evil if you're a designer. When you need to build an application that people will actually use and need to be productive, you need to look over those things to see if they could make the entire application better. Just don't abuse.
      • >>Isn't filling country, state and city automatically nice when a user enters a zip code?

        Show me a site that does this via JavaScript? The Zipcode database is HUGE, and I doubt anyone is downloading the whole thing on pageload just to auto fill in City/State via Zip.

        Don't get me wrong, I love JavaScipt (used right), and I think it really gets a bad wrap because of the pop-up issue.

        • Depends on what the scope is, and you don't need to load everything in the first place anyway.

          I'll just use an example from Frank Boumphrey (Source: http://conf.phpquebec.org/main.php/en/cdrom2004/s e ssion#3), this system was used for an hospital, only the local/frequent zip codes were sent to the client in the first place. Once again, this was for an internal application, but it can really apply anywhere.

I get sick of sites wiping the entire screen only to reload the exact same HTML for their "menu" every time you open a different option. Frames are not evil unless the user is an idiot, and a huge portion of internet users are still using 56k or slower modems.

    • If you want a frame like interface use absolute positioning of the menu content in CSS.
      • Well, sure, you can do that, but then you have to include the menu on every page. Guess what happens when you want to change one of the links on the menu?

        And don't just say "use PHP"; there are lots of situations in which PHP is not a practical option.

        • There are all sorts of ways to manage this in a practical fashion. I'm not saying there are no down sides to this approach, but using frames has far more downsides and maintenance issues.

          Personally, I use either a PHP include file, or an ASP one, depending on the set-up of the webserver - but a simple SSI in a .shtml file will work just the same.

    It seems to me that the whole premise behind this so-called vulnerability is wrong. Frames and windows don't have owners, so there's nothing for the browser to verify.

    So yeah, I think the "a specified design feature of frames" thing is pretty close to the truth.

    • Yeah, I'd hardly call this a vulnerability. Maybe a "feature that can be used to trick users." Of course a parent window can modify content in it's child windows. This isn't exactly news. News would be "a child window can modify content in it's parent window", something that's supposed to require a signed script.

      • Yeah, I'd hardly call this a vulnerability.

        wrong. the Subject line of the parent could be correct, but your statement is wrong. It very well could be a design issue, thus it's not a bug. A correctly implemented design issue is not a bug. However a properly (or improperly) implemented design decision can very well lead to a vulnerability. I see no difference between a vulnerability and "Maybe a 'feature that can be used to trick users.'"

      • Parent window? Child window?

        Different windows. Open a new copy of your browser, doesn't matter how...

        This is a vulnerability because no matter how separate the user tries to keep two windows (for instance, using a bookmark to open ImportantBanking.com rather than clicking on a link to ImportantBanking.com from an untrusted external website), an untrusted external website can change the content in a frame of the ImportantBanking.com window.

        • Ah, that explains the rabid "this is crazy serious" comments. I RTFA, just not TFC. I thought this was just doing the obvious thing, and using javascript to manipulate a browser window that had been opened by the parent. Thanks for the clarification.

          • Actually, the article is not entirely clear on this matter. I went ahead and verified (in IE, can't verify that that's the problem in every browser ;-) that it was more serious than that before I considered it serious, too.

    • I think the problem might be if you have a window open- like a banking site up, or ebay, amazon etc. etc., and you open another website; or somebody sends you spam with html attachment or something.

      As soon as it gets executed javascript replaces the real page with a fake one. If you don't notice the switch then the 'fun' ensues as you try to 'log back in'.

    Description:
    A 6 year old vulnerability has been discovered in multiple browsers, allowing malicious people to spoof the content of websites.

    The problem is that the browsers don't check if a piece of black electrical tape is on the screen covering the address bar, which prevents the user from identifying the source of content in the browser window.

    Successful exploitation allows a malicious website to load arbitrary content with its source masked by the black tape. The user cannot know if this is a trusted site.

    If you use dynamic frame names (even just change them statically every day or every few hours) then you have little to worry about.

    I just checked - indeed - works in Netscape 7.1 and doesn't in Firefox 0.9.1. However, it doesn't work anymore in Netscape if you open the page as a tab instead of another window. Somehow tabs don't work very well with frame names, at least in Netscape.
    It's actually implementation issue - for most browsers - letting other pages swap frames in framesets that don't belong to them. Whoever said that frames don't have owners - it's not quite true - frames are hierarchical to some degree, so it's not so difficu

    Nothing to see, move along...


  • I am curious how long this problem has been around.

    I checked and duplicated the problem on Netscape 7.1 and Firefox .8
    However the problem does not exist with Netscape Communicator 4.8 and probably never has since I recall the original Netscape documentation containing information on security that frames could only be changed by frames from the same domain.

    Anyone running IE with the current help file keylogger problem is asking for worse than spoofing.

  • I just ran their test and it did not work on me. It loaded the page in a new tab instead of the MSN frame. I have Tabbed Browser Extensions installed with nearly everything set to open in a new tab.

    I'm not sure what setting it is. I've done everything but disable the extension and it still opens in a new tab instead of the frame. So looks like they did not do very extensive testing.

    I also tried it on a Windows 98 computer with a fresh install of FireFox 0.9.1 with no extensions installed and it doesn't wo

  • You insensitive clods, my web browser [dotgeek.org] doesn't even have tables, let alone frames.

    It was something Tom Duff wrote at Bell Labs before moving on to Pixar.

  • This affects all browsers I've tried it on. When you click in a "hyperlink" it brings you to a page without asking you specifically if you would like to switch pages. Things to watch out for is the mouse pointer changing to a finger. In fact, if you pointer does change to a finger, you're probably vulnerable. The most shocking aspect is even Lynx is vulnerable to this web bug.
  • To me IE is the vulurability.
