What is broken authentication?

Authentication is “broken” when attackers are able to compromise passwords, keys or session tokens, user account information, and other details to assume user identities. Due to poor design and implementation of identity and access controls, the prevalence of broken authentication is widespread.

What is an example of broken authentication?

Broken authentication examples

The use of lists of known passwords, is a common attack. If an application does not implement automated threat or credential stuffing protections, the application can be used as a password oracle to determine if the credentials are valid.

What is solution of broken authentication?

Implement Multi-Factor Authentication (MFA)

OWASP's number one tip for fixing broken authentication is to “implement multi-factor authentication to prevent automated, credential stuffing, brute force, and stolen credential reuse attacks.”

How do attackers detect broken authentication?

Attackers can detect broken authentication using manual means and exploit them using automated tools with password lists and dictionary attacks. Attackers have to gain access to only a few accounts, or just one admin account to compromise the system.

What may cause broken authentication risk?

1) Broken Authentication Examples

Session Hijacking: As explained above, verified Session IDs may be hijacked impersonate user identities. If a user forgets to log off from a public computer, any other individual can continue that session using the same Session ID that was previously created for the original user.

2017 OWASP Top 10: Broken Authentication

Which of the following scenarios are most likely to result in broken authentication?

Which of the following scenarios is most likely to result in broken authentication and session management vulnerabilities? Poorly implemented custom code is used.

What is the difference between broken authentication and broken access control?

Authentication is the process of verifying the identity of a given user or client. In other words, it involves making sure who they really are. On the other hand, authorization (or access control) is the process of verifying an entity's identity.

When was broken authentication discovered?

Since 2004, it reports the most critical risks affecting web applications — broken authentication first appeared on its 2004 list and remains there today.

What mitigation techniques can be adopted to avoid broken authentication and session management problems?

What is authentication bypass vulnerability?

1) Authentication bypass vulnerability (CVE-2021-27215)

This allows an attacker to login to the admin panel with a user of his choice, e.g the root user with highest privileges or even a non-existing user. An attacker needs to have network access to the admin interface.

What are injection attacks?

During an injection attack, an attacker can provide malicious input to a web application (inject it) and change the operation of the application by forcing it to execute certain commands. An injection attack can expose or damage data, and lead to a denial of service or a full webserver compromise.

What methods could be used to mitigate broken access control issues?

Access control is only effective if enforced in trusted server-side code or server-less API, where the attacker cannot modify the access control check or metadata. Deny access to functionality by default. Use Access control lists and role-based authentication mechanisms.

What is credential surfing?

Description. Credential stuffing is the automated injection of stolen username and password pairs (“credentials”) in to website login forms, in order to fraudulently gain access to user accounts.

What is the impact of broken authentication and session management vulnerability?

In summary, broken authentication and session management has the potential to steal a user's login data, or forge session data, such as cookies, to gain unauthorized access to websites. However, there are clear and easy solutions to prevent your site from being affected by this vulnerability.

What is authentication in security testing?

In computer security, authentication is the process of attempting to verify the digital identity of the sender of a communication. A common example of such a process is the log on process.

What are Owasp top 10 vulnerabilities?

What is the ranking of the broken authentication and session management vulnerability?

As a result, broken authentication and session management vulnerabilities are considered as the Top 2 vulnerabilities on the OWASP list since using a valid user's credentials is the easiest way for attackers to access off-limits systems.

Which of the below are examples of weak authentication flaws?

What threat are you vulnerable to if you do not validate authorization?

12) Mention what is the threat you are exposed to if you do not verify authorization of user for direct references to restricted resources? You are exposed to threat for insecure direct object references, if you do not verify authorization of user for direct references to limited or restricted resources.

What are the example attacks of identification and authentication failures?

Other examples of Identification and Authentication Failures are: No validation of weak passwords. Weak credential recovery and forgot-password processes. Using plain text or weakly hashed passwords data stores.

Why is session hijacking successful?

One of the most valuable byproducts of this type of attack is the ability to gain access to a server without having to authenticate to it. Once the attacker hijacks a session, they no longer have to worry about authenticating to the server as long as the communication session remains active.

What is a cryptographic failure?

Therefore, a Cryptographic Failure vulnerability is a broad vulnerability category that encompasses all types of attacks that are related to anything cryptography related. As one could imagine, a vulnerability of this type could lead to serious consequences, as cryptography is meant to secure sensitive information.

What causes broken access control?

Common access control vulnerabilities include: * Bypassing access control checks by modifying the URL, internal application state, or the HTML page, or simply using a custom API attack tool. * Allowing the primary key to be changed to another's users record, permitting viewing or editing someone else's account.

Which is the best example of broken access control?

Examples of broken access control. Insecure ID's: When looking for something in a database, most of the time we use a unique ID. Often, this ID is used in the URL to identify what data the user wants to get.

Is Csrf broken access control?

CSRF: Client-Side Request Forgery

This is another vulnerability in the Broken Access Control category. In short, CSRF targets victim users, hence the term Client-Side, to unwillingly send a request from their own Web Browsers.
