Insufficient Authentication & Authorization

Vulnerability Assessment as a Service (VAaaS)

Tests systems and applications for vulnerabilities to address weaknesses.

Insufficient (AuthN/AuthZ) authentication and authorization refer to a security vulnerability where an application or system does not properly verify the identity of users or fails to enforce proper access controls.

Authentication is the process of verifying the identity of a user, typically through the use of credentials such as a username and password. Authorization refers to the process of determining whether a user is permitted to perform a certain action or access a particular resource.

When an application or system has insufficient authentication and authorization controls, it can allow unauthorized users to access sensitive information or perform actions they should not be able to. This can result in a range of security issues, including data breaches, data loss, and unauthorized access.

Example of vulnerable code on different programming languages

in Python:

				
					
password = input("Enter your password: ")

				
			


In this code example, the program prompts the user to enter a password, but there is no actual authentication taking place. This means that any user can enter any password, and the program will accept it as valid. This is a vulnerability because it does not properly verify the user’s identity, and could allow unauthorized access to sensitive information or functions.

in Java:

				
					String password = "mypassword";
				
			


In this code example, the program stores a user’s password in plain text, rather than hashing or encrypting it. This means that if an attacker gains access to the system, they can easily read the user’s password and use it to access other resources or services. This is a vulnerability because it does not properly protect user credentials, and could lead to unauthorized access or data breaches.

in JavaScript:

				
					const password = "mypassword";
fetch("/login", {
  method: "POST",
  body: JSON.stringify({username: "myusername", password: password})
});
				
			


In this code example, the program sends the user’s password in plain text over the network, rather than using a secure protocol like HTTPS. This means that if an attacker intercepts the network traffic, they can easily read the user’s password and use it to access other resources or services. This is a vulnerability because it does not properly protect user credentials, and could lead to unauthorized access or data breaches.

Examples of exploitation Insufficient Authentication & Authorization

SQL Injection Attack:

If an application is vulnerable to SQL injection attacks, an attacker can use this vulnerability to bypass authentication and access unauthorized information. For example, if an application allows users to login by entering a username and password, an attacker can use a SQL injection attack to bypass the password check and login as any user they want.

Privilege Escalation:

If an application does not properly enforce access controls, an attacker can exploit this vulnerability to gain access to resources or perform actions that they should not be able to. For example, if a user has access to a low-privilege account, they can exploit this vulnerability to elevate their privileges and gain access to a higher-privilege account.

Session Hijacking:

If an application does not properly manage user sessions, an attacker can exploit this vulnerability to take over a user’s session and access resources that they should not be able to. For example, if a user is logged into an application and the application does not use secure cookies or tokens, an attacker can steal the user’s session ID and use it to access the application as the user.

Brute Force Attack:

If an application does not have proper login rate limiting, an attacker can exploit this vulnerability to perform a brute force attack against the authentication system. For example, if an application allows unlimited login attempts without any delays, an attacker can use a script to try different combinations of usernames and passwords until they find a valid combination.

Privilege escalation techniques

Exploiting Vulnerable Applications:

If an attacker is able to exploit a vulnerability in an application that is running with elevated privileges, they can potentially gain access to those elevated privileges themselves. For example, if an attacker is able to exploit a buffer overflow vulnerability in a system service, they may be able to execute their own code with the same elevated privileges as the service.

Exploiting Misconfigured Services:

If a system has services or processes running with elevated privileges that are misconfigured, an attacker may be able to exploit these misconfigurations to gain access to those elevated privileges. For example, if a service is running with elevated privileges and the system administrator has not properly restricted access to that service, an attacker may be able to exploit this misconfiguration to gain access to the elevated privileges.

Stealing or Cracking Passwords:

If an attacker is able to steal or crack the password of a user with elevated privileges, they can potentially gain access to those elevated privileges themselves. For example, if an attacker is able to steal the password of a system administrator, they may be able to use that password to gain access to the administrator’s privileges.

Using Social Engineering Techniques:

If an attacker is able to manipulate a user with elevated privileges to perform an action on their behalf, they can potentially gain access to those elevated privileges themselves. For example, if an attacker is able to convince a user with elevated privileges to install a malicious application or modify a configuration file, the attacker may be able to gain access to the elevated privileges of that user.

Exploiting Local File Inclusion Vulnerabilities:

If a system has a local file inclusion vulnerability, an attacker may be able to exploit this vulnerability to gain access to sensitive information, including passwords or other credentials. For example, if an attacker is able to include a configuration file that contains passwords for users with elevated privileges, they may be able to use those passwords to gain access to the elevated privileges.

Conclusion

Insufficient Authentication & Authorization (IAA) is a web application vulnerability that occurs when applications don’t properly authenticate users or enforce access controls, leading to unauthorized access and malicious actions. To prevent IAA vulnerabilities, developers and security professionals should use strong passwords, role-based access controls, secure authentication mechanisms, and regularly test and review code. Attackers can exploit IAA vulnerabilities using automated scanning tools, manual penetration testing, and social engineering techniques, which can result in privilege escalation, unauthorized access, and account takeover attacks. Mitigations include implementing multiple security defenses such as intrusion detection and prevention systems, firewalls, and access controls, using a secure development lifecycle, and conducting regular security testing and code reviews.
