Slashdot News Story | YouTube Hit By HTML Injection Vulnerability

The evolution of this bug exploit was quite interesting to follow up close.

At first it simply prevented any further comments to be posted.
Then text was added.
Then the text was scrolling.
Suddenly, the entire page was blacked out except for the added text.

And that’s when the more technical minded people realized much much more was possible.
Bam! Popups!
Infinite popups that lead to browser crashes!
Page redirects to shock sites!
The most sophisticated version I saw actually replaced the Youtube video in-place with the 1man1jar video..

And when the exploit was blocked in the comments, it had a small resurgence as video reply title, before being smacked down once more.

Glorious.
