Exploit Title：PHPMyWind 5.3 has XSS
|
||
Exploit Author:小雨
|
||
Vendor Homepage:http://phpmywind.com
|
||
Software Link:http://phpmywind.com/downloads/PHPMyWind_5.3.zip
|
||
Version:5.3
|
||
CVE:CVE-2017-12984
|
||
|
||
|
||
$r= $dosql->GetOne("SELECT Max(orderid) AS orderid FROM `#@__message`");
|
||
$orderid= (empty($r['orderid']) ? 1 : ($r['orderid'] + 1));
|
||
$nickname= htmlspecialchars($nickname);//游客(xxx)
|
||
$contact= htmlspecialchars($contact); //联系方式
|
||
$content= htmlspecialchars($content); //留言内容
|
||
|
||
$posttime= GetMkTime(time());
|
||
$ip= gethostbyname($_SERVER['REMOTE_ADDR']);
|
||
|
||
|
||
$sql= "INSERT INTO `#@__message` (siteid, nickname, contact, content, orderid, posttime, htop, rtop, checkinfo, ip) VALUES (1, '$nickname', '$contact', '$content', '$orderid', '$posttime', '', '', 'false', '$ip')";
|
||
if($dosql->ExecNoneQuery($sql))
|
||
{
|
||
ShowMsg('留言成功，感谢您的支持！','message.php');
|
||
exit();
|
||
}
|
||
}
|
||
可以看出使用htmlspecialchars进行过滤,带入库中.
|
||
跟进content参数。

后台直接取出content参数,数据并未进行转义操作。
