CVE-2022-22971 is a denial of service vulnerability that affects versions of the Spring Framework prior to 5.3.20 and 5.2.22. The flaw allows authenticated users to exploit a STOMP over WebSocket endpoint, leading to significant disruption in service availability. Organizations using affected versions are at risk of service interruption, which can impact critical operations.
The vulnerability has been assigned a CVSS score of 6.5, placing it in the medium severity category. This rating indicates a moderate level of risk to organizations, given the potential for disruption in services. Exploitation requires low privileges and does not necessitate user interaction, making it a relatively straightforward attack for a malicious actor.
As of now, no public exploit has been confirmed, but the existence of a proof of concept on GitHub suggests that attackers may develop tools to exploit this vulnerability. It is crucial for organizations to remain vigilant and take proactive measures to mitigate the risks associated with CVE-2022-22971.
Organizations should prioritize patching immediately to protect their applications from potential denial of service attacks. This vulnerability highlights the importance of maintaining up-to-date software and implementing robust security practices.
Vulnerability Details
The official description of this vulnerability states: "In spring framework versions prior to 5.3.20+, 5.2.22+ and old unsupported versions, application with a STOMP over WebSocket endpoint is vulnerable to a denial of service attack by an authenticated user." The CVSS score of 6.5 indicates a medium severity, which reflects a high impact on availability.
Affected versions include Spring Framework versions from 5.2.0 to 5.2.21 and 5.3.0 to 5.3.19. The vulnerability falls under CWE-770, which pertains to insufficiently protected credentials.
Technical Analysis
The root cause of CVE-2022-22971 lies in the handling of STOMP over WebSocket endpoints within the Spring Framework. An authenticated user can exploit this endpoint, leading to a denial of service. The attack vector is network-based, and the complexity of the attack is low, indicating that it can be easily executed by an attacker with minimal prior knowledge.
The impact of this vulnerability is significant, with high availability impact but no confidentiality or integrity impact. Attackers may leverage this vulnerability to disrupt services, making it imperative for organizations to take action.
Risk & Impact Analysis
Risk to organizations includes potential denial of service that can affect customer experience and operational continuity. The blast radius for this vulnerability is confined to applications using the affected versions of the Spring Framework, but the potential for disruption is significant.
Given the CVSS score of 6.5 and the lack of public exploits, organizations should address this vulnerability in their priority patch cycle. The urgency for defenders is high, considering the ease of exploitation and the potential impact on availability.

Affected Versions
Affected products include the Spring Framework versions from 5.2.0 to 5.2.21 and 5.3.0 to 5.3.19. Organizations should assess their deployments to determine if they are using vulnerable versions and take appropriate action.
Mitigation & Remediation
Organizations should upgrade to Spring Framework version 5.3.20 or later, or 5.2.22 or later to remediate this vulnerability. If immediate patching is not possible, review configurations to limit exposure and consider implementing network controls to restrict access to vulnerable endpoints.
For further guidance on security testing, organizations can engage in penetration testing to identify similar weaknesses.
Detection Guidance
Monitor logs for indicators of denial of service attempts, such as repeated connection requests from authenticated users. Behavioral anomalies, such as unusual patterns of activity on WebSocket endpoints, should also be flagged. Implementing network signatures can help in identifying potential exploitation attempts.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2022-22971 lies in its demonstration of how even well-known frameworks can harbor critical vulnerabilities. This incident underscores the necessity for robust vulnerability management practices, as threats continue to evolve.
Organizations should consider implementing a comprehensive vulnerability management program to proactively address such vulnerabilities in the future.
Additionally, adopting a strategy for penetration testing methodology can help identify vulnerabilities before they are exploited.
Finally, engaging in regular web application security testing will further strengthen defenses against similar threats.
