Reino: Security Features

La seguridad de un software no es un software de seguridad. Nos preocupamos de cuestiones como la autenticación, el control de acceso, la confidencialidad, la criptografía y la gestión de privilegios.

Insecure Transport: Mail Transmission

Abstract

Establecer una conexión no cifrada a un servidor de correo permite a un usuario malintencionado llevar a cabo un ataque de tipo "man-in-the-middle" y leer todas las transmisiones de correo.

Explanation

Los datos confidenciales enviados sin cifrar a través de la conexión pueden ser leídos/modificados por cualquier usuario malintencionado que intercepte el tráfico de red.

Ejemplo 1: el siguiente SmtpClient está configurado incorrectamente, no utiliza SSL/TLS para comunicarse con un servidor SMTP:


  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);

Ejemplo 1: La siguiente instancia de Spring Mailer está configurada incorrectamente, no usa SSL/TLS para comunicarse con un servidor SMTP:


<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>
