Authentication Bypass
Summary
Authentication Bypass describes an ability bypass the authentication mechanism of the application.
Description
An authentication bypass is a security vulnerability that allows an attacker to gain unauthorized access to protected areas of the application without providing valid credentials. These capabilities can be achieved through various methods, such as exploiting flaws in the authentication process, session management, or by manipulating the application's logic. Attackers leveraging Authentication Bypass can circumvent the standard authentication mechanisms of the application and gain privileged access, leading to unauthorized actions, data exposure, or complete compromise of the application's security.
Remediations
- Implement proper authentication mechanisms including password policies, multi-factor authentication, and rate-limiting.
