Hey geeks, it4chis3c (Twitter) here with one more write-up on tricks & tips to detect Broken Authentication vulnerability.

1. Brief Description

Broken Authentication is a critical web application vulnerability that arises when an application’s authentication mechanisms are flawed, allowing attackers to compromise passwords, keys, or session tokens. This vulnerability is often exploited by attackers to gain unauthorized access to user accounts or systems, leading to data breaches and other security incidents. Broken Authentication can result from weak password policies, poor session management, or inadequate multi-factor authentication.

2. Where to Detect

Detecting Broken Authentication vulnerabilities requires a thorough examination of the authentication process within the application. Key areas to focus on include:

• Login Mechanisms: Check for vulnerabilities in the login process, such as weak password enforcement, lack of account lockout mechanisms, and improper handling of authentication tokens.
