Help With Javascript Injection

[drewdaniels 0]

So I'm taking drivers ed at idrivesafely.com, and each page has a timer must countdown before you can move on to the next page. Ive already taken drivers ed once but it was a scam so i have to do it again, and i dont want to wait on each page. heres the 'javascript:continueNextPage();' function:

Someone please look through this and help me find the injection command to bypass this timer.

You don't want to watch the films?

in the address bar of you browser:

javascript: alert(dunn(return true));

OR

alert(window.theViewer.getVariable('tPlayValue') = true;)
alert((vTotalTime = 300);

I know FF will execute js from the address bar, not too sure about other browsers, though. You'll need to use alert() to hold the code w/o generating errors. The second idea, is a shot in the dark since you didn't post the code for the viewer application. So, you'll probably need to find a way to escape the single quotes. I know it is possible, I've done it before, but forgot how. If you get stuck just google something like, "XSS encode OR escape single quotes".

There are several ways to trick it. It's just a matter of finding something that isn't tamper resistant. Looking at the code it isn't too sophisticated at all. I'm not too good w/ js either, but I think you want to look at dunn(), and the preceding the function.

I haven't taken driver's ed in years, but do remember understanding content before the test proved a good idea.

It's not just the movies but the page timer. And I've already taken drivers Ed but the DMV didn't accept it as a legit source even though I passed the test
