    Concerning latest Phorum version (3.3.2)
    
    A bug in the PHP based forum script Phorum makes it possible to obtain
    the email addresses of the 10 most active users. In the 'admin/'
    directory of the forum there is a script called 'stats.php' that allows
    administrators (and anyone else, since there is no password check on
    this PHP script) to view the 10 most active users of the phorum
    
    Exploit:
    Point the browser to:
    http://www.example.com/phorum/admin/stats.php
    Select the range of statistics analysis and it will show some numbers
    plus the ten most active users including their email addresses.
    
    Workarounds:
    - Delete the script
    - Rename the admin directory
    - Password-protect the admin directory
