DESCRIPTION:
Kacper has discovered a vulnerability in Minerva, which can be
exploited by malicious people to compromise a vulnerable system.

Input passed to the "phpbb_root_path" parameter in
stat_modules/users_age/module.php is not properly verified before
being used to include files. This can be exploited to execute
arbitrary PHP code by including files from local or external
resources.

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in version 2.0.8a Build 237.
Other versions may also be affected.

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