Description:
Kw3[R]Ln has discovered a vulnerability in phpBB Premod Shadow, which can be exploited by malicious people to compromise a vulnerable system.
Input passed to the "phpbb_root_path" parameter in includes/functions_portal.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from external and local resources.
Successful exploitation requires that "register_globals" is enabled.
The vulnerability has been confirmed in version 2.7.1. Other versions may also be affected.
Solution:
Edit the source code to ensure that input is properly verified.
Set "register_globals" to "Off".
