Insecure design of multi-factor authentication

  Insecure design з web Програма з multifactor authentication (MFA) є a вразливість that occurs when в design of the аутентифікація system does not provide в appropriate level з Служба підтримки. This can manifest itself в a variety з forms, including inadequately secured credentials, breach з trust boundaries, и others. Multifactor аутентифікація є typically a system that requires в користувач Для provide two чи more аутентифікація factors. However, if це system є not implemented securely, IT can be susceptible Для мережах. For example, verification codes sent via SMS may be intercepted, чи SIM замінити fraud may occur. To avoid these вразливі місця, ITs important Для follow secure design principles. This includes integrating threat modeling into refinement sessions (чи similar activities), looking for changes в data flows, и access контроль чи other Служба підтримки mechanisms. Its also worth noting that в full benefit з multifactor аутентифікація є only achieved by verifying a few different factors. Verifying в same factor в two different ways є not true twofactor аутентифікація. Its important Для remember that even в most secure design can be susceptible Для вразливі місця if IT‘s not implemented correctly. Therefore, IT є important Для pay attention Для both в design и implementation з в аутентифікація system.

Приклад уразливого коду на різних мовах програмування:

				
					# Insecure MFA design: Sending OTP via email but not verifying it
def send_otp(email):
    otp = generate_random_otp()  # Assume this function generates a random OTP
    send_email(email, otp)  # Assume this function sends the OTP to the given email
    return True

def authenticate(email, password):
    if check_credentials(email, password):  # Assume this function checks the credentials
        return send_otp(email)
    else:
        return False

				
			

  In the above Python code, an OTP is sent to the user’s email after successful password authentication. However, the OTP is never verified, making the second factor of authentication useless.

				
					// Insecure MFA design: Storing OTP in a readable cookie
function sendOTP(email) {
    var otp = generateRandomOTP();  // Assume this function generates a random OTP
    document.cookie = "otp=" + otp;
    sendEmail(email, otp);  // Assume this function sends the OTP to the given email
}

function authenticate(email, password) {
    if (checkCredentials(email, password)) {  // Assume this function checks the credentials
        sendOTP(email);
        return true;
    } else {
        return false;
    }
}

				
			

  In the above JavaScript code, an OTP is stored in a cookie on the client side after successful password authentication. This is insecure because cookies can be easily read by any JavaScript code running on the page, making the OTP vulnerable to theft.

Examples of exploitation with screenshots:

Try Login: admin and Password: admin, and we see thaht is “Invalid credentials!” 

Than open by Оглянути

Find the string :

<label for=“login”>Login</label>

<font color=white“>tonystark</font>

 

Change color=“white” Для “black”

Now Login: tonystark became VISIBLE !!!

Repeat the process for:

<label for=“password”>Password:</label>

<font color=“white”>I am Iron Man</font>

Change  color=“white” Для “black”

And “voilà” (it’s in French)…

Now Password: I am Iron Man є VISIBLE !!!

Let’s try to enter the Login: tonystark и Password: I am Iron Man

Congratulations Seccessful login!

in the context of web vulnerabilities often involves exploiting weaknesses in access control mechanisms. Here are some techniques that could potentially be used in the context of an insecure design of multi-factor authentication: 

 1. Bypassing Authentication Mechanisms:

If the multi-factor authentication is not properly implemented, an attacker might be able to bypass it and gain unauthorized access. 

 2. Modifying URL Parameters:

Certain URL parameters might be manipulated through unauthorized channels to gain escalated privileges.

 3.  Exploiting Broken Access Controls:

If the application has broken access controls, an attacker might be able to perform actions or access resources they are not supposed to.

 4. Assuming Legitimate User Accounts

An attacker might be able to assume legitimate user accounts and gain unauthorized access to password-protected resources. 

Навантаження for вразливі місця MFA

 Involves several steps: 

 1. Identify the type of MFA used by the application:

MFA requires at least two of the following factors for authentication: 

 2. Something You Know:

Passwords, PINs, and security questions. 

 3. Something You Have:

Hardware or software tokens, certificates, email, SMS, and phone calls. 

 4. Something You Are: 

Fingerprints, facial recognition, iris scans, handprint scans, and behavioral factors. 

 5. Location:

Source IP ranges, and geolocation. 

 6. Determine whether the MFA implementation is robust and secure:

This involves checking if the MFA is consistently enforced across all login methods. 

 7. Attempt to bypass the MFA:

If the authentication is done in multiple steps, it may be possible to bypass it by completing the first step of the authentication process (entering the username and password), and then force-browsing to the application or making direct API requests without completing the second stage (entering the MFA code). 

Checklist for preventing insecure design з MFA: 

 1. Collect and negotiate the business requirements:

This includes the protection requirements concerning confidentiality, integrity, availability, and authenticity of all data assets and the expected business logic. 

 2. Compile the technical requirements:

This includes functional and non-functional security requirements. 

 3. Plan and negotiate the budget:

This covers all design, build, testing, and operation, including security activities. 

 4. Secure Design: 

This is a culture and methodology that constantly evaluates threats and ensures that code is robustly designed and tested to prevent known attack methods. 

 5. Threat modeling:

This should be integrated into refinement sessions (or similar activities); look for changes in data flows and access control or other security controls. 

 6. Implement multi-factor authentication:

This is the best defense against the majority of password-related attacks, including brute-force attacks. 

 Remember, these are just potential techniques and preventative measures. The actual methods of exploitation and prevention can vary greatly depending on the specific circumstances and the design of the multi-factor authentication system.
