DESCRIPTION:
bd0rk has discovered a vulnerability in the Addressbook module for
PHP-Nuke, which can be exploited by malicious people to disclose
sensitive information.

Input passed to the "module_name" parameter in
modules/Addressbook/addressbook.php is not properly verified before
being used to include files. This can be exploited to include
arbitrary files from local resources.

Successful exploitation requires that "register_globals" is enabled,
"magic_quotes_gpc" is disabled, and that the system is running PHP
5.

The vulnerability is confirmed in version 1.2. Other versions may
also be affected.

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