CRITICAL: Highly critical

DESCRIPTION: xoron has reported a vulnerability in phpBB++, which can be exploited by malicious people to compromise vulnerable systems. Input passed to the "phpbb_root_path" parameter in includes/functions.php is not properly verified before being used to include files. This can be exploited to include arbitrary files from local or external resources. Successful exploitation requires that "register_globals" is enabled. The vulnerability is reported in Build 101. Other versions may also be affected.

SOLUTION: Edit the source code to ensure that input is properly verified.
