VULN EXPLANATION

look at include/main.php, checkLogin function:

function checkLogin()
{
global $username, $userpassword, $userID,$conn;
global $user_name, $user_pass, $admin_privs,$designer_privs,$affiliate_privs;

session_start();
session_register("session");
if ($user_name == "" AND $username == "")
{
header("Location:index.php");
}
elseif ($user_name != "" OR $username != "")
{
$sql_user_name = $user_name;
$md5_pass = md5($user_pass);

$sql = "SELECT * FROM UserDB WHERE user_name='$sql_user_name' and user_password='$md5_pass'";
$ADODB_FETCH_MODE = ADODB_FETCH_ASSOC;
$recordSet = $conn->Execute($sql);
$num = $recordSet->RecordCount();
if ($num == 1)
{
[...]
session_register("admin_privs");
[...]
}
else
{
header("Location:index.php");
}
} // end elseif

mmm.. there isn't any exit or die() after header('Location: index.php')..
so the first part of the security can be bypassed..

now look at admin/changeinfo.php:

<?php
include("../include/common.php");
include("../include/main.php");
global $conn,$config;
checklogin();
if($admin_privs=='yes')
{
[...]
}

if you are a legal user, $admin_privs will be the value of $_SESSIN[admin_privs],
but if you aren't logged in this session simply do not exist, and you can inject
the proper value trough the URL..
