CVE-2023-34055 is a medium-severity vulnerability affecting VMware Spring Boot versions 2.7.0 to 2.7.17, as well as 3.0.0 to 3.0.12 and 3.1.0 to 3.1.5. This vulnerability allows attackers to send specially crafted HTTP requests, which can trigger a denial-of-service (DoS) condition in the application. The risk to organizations includes service disruptions and potential downtime, making it critical to address this vulnerability swiftly.
With a CVSS score of 5.3, this vulnerability falls into the medium severity category. The attack vector is network-based, and it has a low attack complexity, meaning that it can be exploited relatively easily. Organizations utilizing the affected versions of Spring Boot should prioritize remediation efforts to mitigate potential impacts.
Currently, there are no known public exploits for this vulnerability, nor is it classified as actively exploited. However, the potential for a denial-of-service condition poses a real risk for organizations that rely on the affected software. Therefore, organizations should prioritize patching immediately.
In summary, organizations using VMware Spring Boot versions 2.7.0 to 2.7.17, 3.0.0 to 3.0.12, or 3.1.0 to 3.1.5 should assess their environments for this vulnerability and take necessary steps to patch or mitigate the risk.
Vulnerability Details
According to the official description, this vulnerability allows a user to provide specially crafted HTTP requests that may cause a denial-of-service (DoS) condition. Specifically, an application is vulnerable when it uses Spring MVC or Spring WebFlux, and has the 'org.springframework.boot:spring-boot-actuator' on the classpath.
The vulnerability has a CVSS score of 5.3, indicating it is medium severity. The attack vector is network-based with low complexity, requiring no privileges or user interaction.
The affected products include all versions of Spring Boot from 2.7.0 to 2.7.17, 3.0.0 to 3.0.12, and 3.1.0 to 3.1.5. The vulnerability was published on November 28, 2023.
Technical Analysis
The root cause of this vulnerability stems from improper handling of HTTP requests that can lead to resource exhaustion. Attackers may leverage this weakness to overload the application, resulting in service interruptions.
The attack vector is primarily network-based, with low attack complexity. No privileges are required to exploit this vulnerability, and no user interaction is necessary. The impact on availability is rated as low, but can still result in significant service disruption.
Confidentiality and integrity impacts are not affected by this vulnerability, focusing solely on denial-of-service concerns.
Risk & Impact Analysis
The real-world deployment risk associated with CVE-2023-34055 is significant, especially for organizations that rely heavily on Spring Boot applications. The potential for a denial-of-service condition could disrupt services and business operations, causing reputational damage and financial loss.
Given the medium CVSS score and the current lack of known public exploits, organizations should still take this vulnerability seriously. High-profile systems that utilize the affected versions are particularly at risk, and the blast radius could affect numerous users and applications.
Organizations should schedule remediation in their priority patch cycle to address this vulnerability and mitigate potential risks.
Exploitation Status
Signal | Status |
|---|---|
Known Exploit | No |
Public PoC | No |
Actively Exploited | No |
Ransomware Use | No |
Affected Versions
The affected versions of Spring Boot are 2.7.0 to 2.7.17, 3.0.0 to 3.0.12, and 3.1.0 to 3.1.5. Organizations using these versions should assess their environments and take necessary action.
Mitigation & Remediation
Organizations should patch to the latest version of Spring Boot to mitigate this vulnerability. If an immediate upgrade is not feasible, consider implementing network controls to limit exposure to potentially malicious requests.
For additional security, organizations can enhance configuration hardening and monitor logs for unusual activity. Regular security testing through penetration testing can also help identify vulnerabilities proactively.
Detection Guidance
To detect potential exploitation of this vulnerability, organizations should monitor application logs for unusual patterns of HTTP requests, specifically those that may lead to resource exhaustion. Behavioral anomalies and spikes in traffic can signal attempts to exploit the vulnerability.
Network signatures can also be established to flag requests that match known patterns associated with denial-of-service attacks.
AppSecure Threat Intelligence Insight
CVE-2023-34055 highlights the importance of ensuring that applications are resilient against denial-of-service attacks. As organizations continue to adopt Spring Boot, understanding the deployment risks associated with this technology is crucial.
This vulnerability represents a trend where seemingly minor issues can have significant impacts on availability. Organizations should learn from such vulnerabilities and implement robust security practices to minimize risk.
For strategic defensive measures, consider leveraging resources for comprehensive security assessments, such as application security assessments, which can help identify potential vulnerabilities before they can be exploited.
Regularly updating security awareness and training for development teams is also essential to maintain a strong defense against new vulnerabilities.
