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。

p:33
<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。
