This exploit is already circulating, so I am posting a notice here.
There is a way to exploit IE's HTML rendering engine to render invalid
HTML code, embedded within a link. This can be used to bypass phpBB's
filtering system to cause a cross site scripting issue.
A description in Russian is available here: http://antichat.ru/txt/phpbb/
PoC is included with the description. I would advise administrators to
disable the rendering of BBCode for the time being, this mitigates the
issue.
