Woltlab Burning Board (wbb) 2.3.6 CSRF/XSS - 0day

Advisory Content :

On my WBB 2.3.3 (and i think, this is the default setting) you cannot
access register.php when logged in (even as admin). So you need to be
logged off to open the evil site. And when you are logged off, the
cookie is simply useless.

Also, on my Forum, only r_dateformat and r_timeformat are affected.

regards
