Authentication hijacking

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

Authentication hijacking refers to the unauthorized access of a user’s account by an attacker who steals the user’s login credentials or session identifier. The attacker can then use this information to gain access to the user’s account and perform actions on their behalf without their knowledge or consent. This type of attack is commonly carried out through techniques such as phishing, session fixation, or man-in-the-middle attacks. Once the attacker gains access to the user’s account, they can potentially steal sensitive information, make unauthorized purchases, or engage in other malicious activities.

Example of vulnerable code on different programming languages:


in PHP:

				
					session_start();
if(isset($_POST['username']) && isset($_POST['password'])) {
  $username = $_POST['username'];
  $password = $_POST['password'];
  if(authenticate($username, $password)) {
    $_SESSION['authenticated'] = true;
    $_SESSION['username'] = $username;
    header("Location: home.php");
  } else {
    echo "Invalid username or password";
  }
}

				
			

 

In this example, the authentication mechanism relies solely on checking the validity of the username and password entered by the user. If an attacker manages to steal the user’s session identifier, they can bypass the authentication check and gain access to the user’s account without having to enter the correct credentials.

• in Java:

				
					HttpSession session = request.getSession();
if(request.getParameter("username") != null && request.getParameter("password") != null) {
  String username = request.getParameter("username");
  String password = request.getParameter("password");
  if(authenticate(username, password)) {
    session.setAttribute("authenticated", true);
    session.setAttribute("username", username);
    response.sendRedirect("home.jsp");
  } else {
    response.getWriter().println("Invalid username or password");
  }
}

				
			

 

This Java example is similar to the PHP code above, except that it uses a session object to store the authentication status and the user’s username. However, if an attacker can hijack the session identifier, they can impersonate the user and access their account without having to enter the correct credentials.

• in Python:

				
					session = requests.Session()
response = session.post("https://example.com/login", data={"username": "alice", "password": "password123"})
if response.status_code == 200:
  print("Login successful")
  session_id = session.cookies.get_dict()["session_id"]
  # Do some authenticated action with the session
else:
  print("Login failed")

				
			

 

In this Python example, the script logs in to a website by sending a POST request with the username and password as parameters. If the login is successful, the script obtains the session identifier from the cookies and uses it to perform authenticated actions. However, if an attacker intercepts the session identifier, they can bypass the authentication check and perform actions on behalf of the user without their knowledge.

Examples of exploitation Authentication hijacking

Stealing sensitive information:

Once an attacker gains access to a user’s account, they can potentially access sensitive information such as personal data, financial information, or confidential business information. The attacker can use this information for identity theft, financial fraud, or corporate espionage.

Making unauthorized purchases:

If the user’s account is linked to a payment method such as a credit card, the attacker can use the account to make unauthorized purchases or transfer money to their own accounts.

Posting malicious content:

An attacker who gains access to a social media account can post malicious content, such as links to phishing sites or malware, that can infect other users or steal their credentials.

Disrupting business operations:

If the user’s account is used for business purposes, such as accessing company resources or performing transactions, an attacker who hijacks the account can disrupt business operations or cause financial loss.

Spreading false information:

An attacker who gains access to a high-profile user’s account, such as a politician or celebrity, can use the account to spread false information or propaganda, potentially causing harm or inciting violence.

Privilege escalation techniques for Authentication hijacking

Session fixation:

An attacker can use the session fixation technique to force the victim to use a session identifier that has been previously created by the attacker. This allows the attacker to hijack the session and gain access to the victim’s account. If the attacker can gain access to an account with administrative privileges, they can use it to escalate their privileges and gain control over the system.

Session hijacking:

An attacker can use the session hijacking technique to steal the victim’s session identifier and use it to hijack the session. This allows the attacker to bypass the authentication mechanism and gain access to the victim’s account. Once the attacker has gained access, they can escalate their privileges by performing actions that are only available to users with higher levels of privileges.

Cross-site scripting (XSS):

An attacker can use an XSS vulnerability to inject malicious code into a web application that is executed in the victim’s browser. The code can steal the victim’s session identifier or perform other actions on the victim’s behalf, such as changing their password or escalating their privileges.

SQL injection:

An attacker can use an SQL injection vulnerability to execute arbitrary SQL commands against a database. This can be used to bypass the authentication mechanism and gain access to the victim’s account. If the attacker can gain access to an account with administrative privileges, they can use it to escalate their privileges and gain control over the system.

Man-in-the-middle (MITM) attack:

An attacker can use a MITM attack to intercept the victim’s traffic and steal their credentials or session identifier. This allows the attacker to bypass the authentication mechanism and gain access to the victim’s account. If the attacker can gain access to an account with administrative privileges, they can use it to escalate their privileges and gain control over the system.

General methodology and checklist for Authentication hijacking

Methodolohy:

  1. Identify the application’s authentication mechanism: Start by understanding how the application handles user authentication. Determine which authentication protocols and mechanisms are used, such as username/password, OAuth, SAML, or OpenID.

  2. Identify the session management mechanism: Understand how the application manages user sessions, including how session IDs are generated, stored, and verified.

  3. Identify potential entry points for attackers: Look for areas where an attacker may be able to access the application’s authentication or session management functionality. These may include login pages, logout pages, password reset pages, or any page that uses cookies or session tokens.

  4. Test for common authentication bypass techniques: Try common authentication bypass techniques, such as SQL injection, cross-site scripting (XSS), or session fixation/hijacking.

  5. Test for brute-force attacks: Attempt to brute-force the login mechanism to determine if the application enforces account lockout or rate limiting.

  6. Test for weak password policies: Test if the application enforces strong password policies, such as password length, complexity, and expiration.

  7. Test for multi-factor authentication (MFA): Determine if the application supports MFA and test the implementation to ensure it provides sufficient protection against authentication hijacking.

  8. Test for insecure session management: Check if the application uses predictable session IDs or fails to invalidate session tokens after logout or after a certain period of inactivity.

  9. Review source code and configurations: Review the application’s source code and configurations for any vulnerabilities or misconfigurations that may lead to authentication hijacking.

  10. Document and report vulnerabilities: Document any vulnerabilities found during the testing and report them to the application owner or security team. Include detailed information on the vulnerability, its impact, and recommendations for remediation.

Average CVSS score of stack Authentication hijacking

The average CVSS score for vulnerabilities related to authentication hijacking can vary widely depending on the specific vulnerability, its impact, and its exploitability. However, many authentication hijacking vulnerabilities are classified as high-severity vulnerabilities and can have CVSS scores ranging from 7.0 to 10.0 or even higher.

For example, a vulnerability that allows an attacker to bypass authentication and gain unauthorized access to sensitive data or functionality could have a CVSS score of 9.0 or higher. A vulnerability that allows an attacker to hijack an authenticated session could also have a high CVSS score, as it can give the attacker access to the same resources and privileges as the legitimate user.

It’s important to note that the CVSS score is just one factor to consider when evaluating the severity of a vulnerability, and it should be used in combination with other factors such as the potential impact, the ease of exploitation, and the availability of mitigations.

How to be protected from Authentication hijacking

  1. Use strong and unique passwords: Choose passwords that are long, complex, and difficult to guess. Avoid using the same password across multiple accounts.

  2. Implement multi-factor authentication (MFA): MFA adds an extra layer of security to your authentication process by requiring a second form of verification, such as a fingerprint or a code sent to your phone.

  3. Keep your software up to date: Make sure your operating system, web browser, and any other software you use is up to date with the latest security patches.

  4. Use a reputable antivirus/anti-malware software: This can help detect and prevent malicious software that can be used for authentication hijacking.

  5. Use a VPN when connecting to public networks: A VPN encrypts your internet connection and helps protect against eavesdropping and other attacks on public networks.

  6. Be wary of phishing attacks: Phishing attacks can be used to steal your login credentials. Be cautious of suspicious emails, links, and attachments, and never enter your login credentials on untrusted websites.

  7. Monitor your accounts for suspicious activity: Check your account activity regularly to look for any signs of unauthorized access or suspicious activity.

Mitigations for Authentication hijacking

  1. Use secure authentication mechanisms such as SSL/TLS, HTTPS, or SSH to encrypt the communication between the client and server and protect the authentication data from being intercepted or manipulated.

  2. As mentioned earlier, MFA can add an extra layer of security to your authentication process by requiring a second form of verification.

  3. Limit the number of failed login attempts and lockout accounts after a certain number of failed attempts. This can help prevent brute-force attacks.

  4. Use secure session management techniques such as session timeouts and session revocation to prevent session hijacking.

  5. Encourage users to use strong and unique passwords to reduce the risk of password guessing or brute-force attacks.

  6. Implement 2FA for administrative access to critical systems to reduce the risk of unauthorized access.

  7. IDPS can help detect and prevent unauthorized access attempts and alert administrators to potential security breaches.

  8. WAFs can help protect web applications from various attacks, including authentication hijacking, by monitoring and filtering incoming traffic.

Conclusion

Authentication hijacking is a serious security issue that can have significant consequences for individuals and organizations. It involves stealing or manipulating authentication credentials to gain unauthorized access to sensitive information or systems. Attackers can use a variety of techniques to carry out authentication hijacking attacks, including session fixation, session hijacking, and password cracking.

To prevent authentication hijacking, it is important to use secure authentication mechanisms, implement multi-factor authentication, use strong and unique passwords, and monitor accounts for suspicious activity. Organizations can also implement rate-limiting and account lockout, session management, intrusion detection and prevention systems, and web application firewalls to further reduce the risk of authentication hijacking.

Testing for authentication hijacking is an important part of any security assessment, and there are many tools and techniques available to help identify vulnerabilities and mitigate risks. However, it is also important to stay up to date with the latest security trends and best practices to ensure that systems are secure and protected from potential attacks.
