Vulnerability Details
The official description of CVE-2024-38828 states that Spring MVC controller methods with an @RequestBody byte[] method parameter are vulnerable to a DoS attack. This vulnerability falls under the Common Weakness Enumeration (CWE) classification of CWE-400, which pertains to 'Uncontrolled Resource Consumption.'
The CVSS 3.1 score of 5.3 indicates a medium severity, characterized by a low attack complexity. Attackers require no privileges and do not need user interaction to exploit this vulnerability. The potential impact is significant with low availability impact, as it could render the application inoperative.
The vulnerability was published on November 18, 2024. Immediate attention is necessary for any organizations utilizing affected Spring MVC implementations.
Technical Analysis
The root cause of this vulnerability lies in the handling of byte array parameters within Spring MVC controller methods. When these parameters are improperly managed, they can lead to excessive resource consumption, resulting in a denial-of-service condition.
The attack vector is network-based, allowing attackers to exploit this vulnerability remotely. The attack complexity is low, meaning that it does not require advanced skills or tools to execute successfully. No privileges are required for exploitation, and user interaction is not necessary, making it more concerning.
The impacts of this vulnerability are notable, with a low availability impact. Attackers may leverage this vulnerability to disrupt services, thereby affecting the operational capacity of affected applications.
Risk & Impact Analysis
Risk to organizations includes the potential for service disruptions caused by denial-of-service attacks. Given the low attack complexity and lack of privilege requirements, the vulnerability presents a high risk to any organization using affected Spring MVC controller methods.
The blast radius for this vulnerability could affect all users of the application, leading to significant operational and reputational damage. Organizations should assess their security posture and prioritize addressing this vulnerability in the next patch cycle.
With a CVSS score of 5.3, organizations should address this vulnerability in priority patch cycles to mitigate potential impacts.
