CVE-2024-22234

Overview 

Spring Security is a complete framework that provides authentication, authorization, and other security features for Java applications, particularly those built with the Spring Framework.

‍

An Authentication Bypass vulnerability (CVE-2024-22234) has been identified in Spring Security's spring-security-web module, which allows attackers to bypass authentication mechanisms by taking advantage of improper handling of null authentication parameters.

‍

Per OWASP: "Authentication bypass occurs when an attacker is able to gain access to a system without having valid credentials, often due to flaws in the authentication mechanism."

‍

This issue affects versions 6.1.0 to 6.1.6 and 6.2.0 to 6.2.1 of Spring Security's spring-security-web module.

This flaw allows attackers to bypass authentication checks, potentially granting unauthorized access to sensitive resources.

‍

Mitigation

Users of the affected components should apply one of the following mitigations:

• Upgrade affected applications to supported versions of Spring Security.
• Leverage a commercial support partner like HeroDevs for post-EOL security support.
