The result of this vulnerability can lead to full compromise of the browser and maybe even the underlaying operating system. **Don’t try this at home**. ![300 movie trailer](http://www.gnucitizen.org/images/378664681_f0ea7b3b94.jpg) Before we move on, I have to say a few things. Last year I disclosed two highly critical QuickTime vulnerabilities [here](http://www.gnucitizen.org/blog/backdooring-quicktime-movies/) and [here](http://www.gnucitizen.org/blog/backdooring-mp3-files/). The first vulnerability was fixed but the second one was completely ignored. I tried to bring the spot light on the second vulnerability one more time over [here](http://www.gnucitizen.org/blog/myspace-quicktime-worm-follow-up), yet nobody listened. So, I decided to post a demonstration of how a *Low risk* issue can be turned into a very easy to perform **HIGH risk** attack. The exploit is rather simple. But first, here is a simple QTL file which instructs the browser to display a friendly `alert('whats up...')` message on the screen: ``` ``` The most interesting thing about this simple XML file is that we can save it with QuickTime supported extension in order to mislead the user. If you check [about:plugins](about:plugins) you will see that QuickTime supports several media formats. We can use the audio and video formats only. This means that you can paste the above code into files with extensions: **3g2, 3gp, 3gp2, 3gpp, AMR, aac, adts, aif, aifc, aiff, amc, au, avi, bwf, caf, cdda, cel, flc, fli, gsm, m15, m1a, m1s, m1v, m2a, m4a, m4b, m4p, m4v, m75, mac, mov, mp2, mp3, mp4, mpa, mpeg, mpg, mpm, mpv, mqv, pct, pic, pict, png, pnt, pntg, qcp, qt, qti, qtif, rgb, rts, rtsp, sdp, sdv, sgi, snd, ulw, vfw, wav** and others. Enough theory, show me some action. The exploit that gains chrome privileges looks like this: ``` ``` In practice I can do anything with the browser, like installing browser backdoors, and the operating system if the victim is running with administrative privileges. However, just for the sake of this demonstration, I simply open **calc.exe**. Keep in mind that the exploit is **cross-platformed**. If you dare to try this in your browser, here is a list of a few files you have to click on. They are not malicious. You have my word. *BTW, QuickTime comes by default with iTunes. Therefore, iTunes users are most affected*.
