Help with XSS quiz
« on: November 02, 2013, 09:02:01 AM »
Hi,

I wanted to learn about XSS, so I googled a bit about it and then I wanted to test my XSS skills so I again googled about XSS quizes.
I stumbled upon this site: http://xss-quiz.int21h.jp/
and now I am stuck at Level 11
http://xss-quiz.int21h.jp/stage11th.php?sid=29720fb57b40214d8f09f199f2fae75ccdf88483

Basically, it replaces the text 'script' with 'xscript', 'on****' with 'onxxx' and 'style' with 'stxxx'.

I need your help as I am unable to figure it out.

Thanks

I cannot thank you enough :D
I figured it out, first I had to study a little though.
First I closed "> and then an iframe with base64.

Thanks a lot.
