Browser Security

Well the latest modern browsers including Firefox , Chrome can be tricked to show a URL in address bar while I push a different file from other website. Wondering what harm that can cause? Well lets say the cyber criminals design a website that looks like a video player and asks you to update flash player when you try to play, when you click download then you see in your browser address that you are bing redirected to adobe website (its a real adobe flash download URL) but a totally different file can be downloaded. See the screenshot below to have a clear understanding.

    1. Well that’s hard to say. As this problem is also true for Google Chrome, and few other browsers. I have contacted Mozilla hopefully they will fix things in the next version.

  1. Nice info! I really scared when in the archive download it by itself.Pretty nice cloaboration to from your part.Good job.!

  2. why do you see it as a vulnerability ?
    A page can always have content from other page. What you are trying to do is to get another URL after that adobe page loads up, which is perfectly fine.

    1. Its a vulnerability because, say you visit a website which has a flash video player and shows a missing plugin message, you click on the download flash button and you see the adobe flash page open, and the file gets downloaded.Now suppose the file was not a harmless file like the author showed..may be its a trojan that can take over your computer, but a average computer user will not notice the difference. As both the browser and the url bar shows adobe flash player.

        1. Hello Akash, yes a HTML page can have the reference of a file from another page. But a file from different server should not start downloading with a page load of a website of different server. I am sorry if i am unable to explain you why this is a vulnerability. But both Google Chrome and Firefox has now accepted it as a vulnerability and fix is on its way. Thank You.
