Insecure Transport: Mail Transmission

Abstract

通过与邮件服务器建立未加密的连接，允许攻击者进行中间人攻击以及读取所有邮件传输。

Explanation

通过未加密网络发送的敏感数据容易被任何可拦截网络通信的攻击者读取/修改。

示例 1：以下 SmtpClient 的配置不正确，未使用 SSL/TLS 与 SMTP 服务器进行通信：


  string to = "bob@acme.com";
  string from = "alice@acme.com";
  MailMessage message = new MailMessage(from, to);
  message.Subject = "SMTP client.";
  message.Body = @"You can send an email message from an application very easily.";
  SmtpClient client = new SmtpClient("smtp.acme.com");
  client.UseDefaultCredentials = true;
  client.Send(message);

Abstract

如果与邮件服务器建立未加密的连接，攻击者将可发动中间人攻击并读取传输的所有邮件。

Explanation

如果通过未加密的线路发送敏感数据，可能会遭到有权拦截网络通信的攻击者的读取/修改。

示例 1：以下 Spring Mailer 配置不正确，未使用 SSL/TLS 与 SMTP 服务器建立通信：


<bean id="mailSender" class="org.springframework.mail.javamail.JavaMailSenderImpl">
    <property name="host" value="smtp.acme.com" />
    <property name="port" value="25" />
    <property name="javaMailProperties">
        <props>
            <prop key="mail.smtp.auth">true</prop>
        </props>
    </property>
</bean>
