Welcome to yet another XSS puzzle! Before you continue, maybe you should insert your name first.
Rules:
- Execute alert(1) in this origin
- XSS in any latest modern browser (for MSIE the version should be 11). Browser specific solution is accepted
- There is an expected solution
- It has nothing to do with PHP tricks, nor server side magic. You can grab the code and play locally
- You may need to use styles.php
Send your solution to filedescriptor@gmail.com of @filedescriptor if you solved it, and your name will be put here.
Solvers:
- Team Cure53 Mario Heiderich(@0x6D6172696F) and Maxim Rupp(@mmrupp) - solved it with the expected solution (IE only)
- Masato Kinugawa(@kinugawamasato) - solved it with the expected solution (IE only)
- Giuseppe Trotta Ohpe(@Giutro) - solved it with the expected solution (IE only)
Honorable mention: Masato Kinugawa(@kinugawamasato) solved it in IE10 with a bug in the code.
