PHPMyWind_5.3/message.php （25-41）

$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。

<td><textarea name="content" id="content"><?php echo $row['content'] ?></textarea>

后台直接取出content参数,数据并未进行转义操作。
