Here is what happened:
The programmers in Jim-san's office made the HTML pages for the new
http://be.2ch.net. I thought they had properly sanitized and verified everything. I guess I was wrong.
I have taken the new be.2ch.net beta offline for the moment.
I will fix it and properly sanitize and verify all input.
After I fix it, ill put it back online, then you guys can try to find some new XSS vulnerabilities.
Thanks!
