Discussion

PHPBB BBCode Denial Of Service Vulnerability

phpBB is free, open-source web forums software that is written in PHP and backended by MySQL. It will run on most Unix and Linux variants, as well as Microsoft Windows operating systems.

A vulnerability exists in phpBB's implementation of BBcode which makes it possible for an attacker to starve resources on the host running the affected software. This may result in a denial of service to the webserver and possibly the underlying system if adequate resource limits are not in place.

If this issue is successfully exploited, the webserver will need to be restarted for normal functionality to resume.
