---[ the product

Postnuke is a CMS (Contenent Management System) that is an improved
version of php-nuke. You can find it here: http://www.phpnuke.com.

---[ the bug

The pages of the full disclosure path vulnerabilities that are in
the core and in the modules of postnuke are wrote to be included
in other pages, but if you access directly they made a page error
mainly for Unkwon function.


---[ the exploit:

In the core of postnuke you can get an error page visiting this url:

http://www.site_with_postnuke.com/footer.php

In the other modules that are by default in postnuke:

http://www.site_with_postnuke.com/modules/Downloads/admin.php
http://www.site_with_postnuke.com/modules/FAQ/admin.php
http://www.site_with_postnuke.com/modules/Reviews/admin.php
http://www.site_with_postnuke.com/modules/Sections/admin.php
http://www.site_with_postnuke.com/modules/Submit_News/admin.php
http://www.site_with_postnuke.com/modules/Top_List/admin.php
http://www.site_with_postnuke.com/modules/Web_Links/admin.php

---[ the patch

You can protect the page form the direct access as is in the file
header.php, writing this lines at the begin of all the page bugged
in that way:

if (strpos('header.php', $_SERVER['PHP_SELF'])) {
die ("You can't access this file directly...");
}
