Overview
Spring Framework is a powerful and versatile Java application framework designed to simplify enterprise-level development. It provides a comprehensive ecosystem for building robust, scalable, and maintainable applications by offering tools for dependency injection, aspect-oriented programming, data access, transaction management, and more. Seamlessly integrating with other Java technologies, Spring Framework fosters modular development while reducing boilerplate code, enabling developers to focus on business logic. Its flexible, lightweight architecture makes it a go-to choice for creating web, microservices, and enterprise-grade applications.
A Denial of Service (DoS) vulnerability (CVE-2024-38828) has been identified in Spring Framework, which enables attackers to perform DoS attacks.
Per OWASP: The Denial of Service (DoS) attack is focused on making a resource (site, application, server) unavailable for the purpose it was designed. There are many ways to make a service unavailable for legitimate users by manipulating network packets, programming, logical, or resources handling vulnerabilities, among others. If a service receives a very large number of requests, it may cease to be available to legitimate users. In the same way, a service may stop if a programming vulnerability is exploited, or the way the service handles resources it uses.
This issue affects all versions of Spring Framework less than 5.3.42.

Vulnerability Info
A Denial of Service (DoS) attack is a cyberattack aimed at making a system, service, or network unavailable to its intended users. This is typically achieved by overwhelming the target with an excessive amount of traffic or sending it data designed to trigger failures. The goal is to disrupt normal operations, causing slowdowns or complete inaccessibility.
RequestBody byte[] method parameters used in a Spring MVC controller method are vulnerable to a Denial of Service (DoS) attack.

Mitigation
Spring Framework 5.3.x is no longer community-supported. The community support version will not receive any updates to address this issue. For more information, see here.
Users of the affected components should apply one of the following mitigations:
- Upgrade affected applications to supported versions of Spring Framework.
- Leverage a commercial support partner like HeroDevs for post-EOL security support.
- Switch from using @RequestBody byte[] to InputStream.
