CVE-2024-45590 is a high-severity vulnerability affecting the openjsf body-parser middleware, specifically versions prior to 1.20.3. This vulnerability allows denial of service when URL encoding is enabled, enabling a malicious actor to flood the server with a large number of requests. The issue has been patched in version 1.20.3, and organizations using this middleware should prioritize upgrading to this version to mitigate risk.
The CVSS score for this vulnerability is 7.5, indicating a high severity level, which necessitates immediate attention from organizations. The potential impact is significant as it could lead to service disruption, affecting application availability. Given that this vulnerability has known exploits, it is crucial for organizations to address this vulnerability in their systems as soon as possible.
Organizations should prioritize patching immediately. The exploitability of this vulnerability is high, and rapid remediation is essential to prevent attackers from leveraging this weakness in their systems.
This vulnerability highlights the importance of maintaining up-to-date software components and understanding the risks associated with third-party dependencies. Regular audits and vulnerability assessments should be part of an organization's security strategy.
Vulnerability Details
The body-parser middleware is essential for parsing incoming request bodies in a middleware before handlers, particularly for Node.js applications. The vulnerability allows denial of service attacks due to poorly handled URL encoding, which can be exploited by sending crafted payloads that overwhelm the server.
The CVSS vector for this vulnerability is CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H, confirming that it has a high impact on availability with low attack complexity and no required privileges or user interaction. The vulnerability is classified under CWE-405, indicating resource exhaustion.
This issue was initially published on September 10, 2024, and it is critical for organizations to implement the patch provided in version 1.20.3 to ensure the integrity and availability of their services.
Technical Analysis
The root cause of CVE-2024-45590 lies in the body-parser's handling of URL-encoded data. Specifically, when the URL encoding feature is enabled, a malicious actor can craft specially formatted requests that exploit the middleware's inability to effectively limit the number of concurrent requests, leading to a denial of service.
The attack vector is network-based, allowing attackers to initiate the attack remotely without requiring physical access to the vulnerable system. The attack complexity is low, meaning that even less skilled attackers could exploit this vulnerability effectively. No privileges are required to exploit the vulnerability, and user interaction is not needed, which increases the risk of widespread exploitation.
The impact of this vulnerability is significant, with a high availability impact as the server becomes unresponsive under the load of crafted requests. The confidentiality and integrity impacts are rated as none, as the vulnerability does not involve unauthorized access to sensitive data or alteration of data.
Risk & Impact Analysis
The real-world risk associated with CVE-2024-45590 is substantial, particularly for organizations relying heavily on Node.js applications that utilize the body-parser middleware. The potential for service disruption can lead to significant operational downtime, loss of revenue, and damage to reputation.
Organizations that experience denial of service may find themselves unable to serve customers, which could result in lost business and trust. The urgency level for addressing this vulnerability is high, given its exploitability and impact on availability.
Organizations should assess the blast radius of this vulnerability within their systems, especially in microservices architectures where the body-parser is widely used. Implementing the patch promptly will mitigate the risk of exploitation and secure the application environment.

Affected Versions
The vulnerable versions of the body-parser middleware include all versions prior to 1.20.3. Organizations should ensure they are running the latest version to prevent potential exploitation.
Mitigation & Remediation
To remediate this vulnerability, organizations should upgrade the body-parser middleware to version 1.20.3 or later. If immediate upgrading is not feasible, consider implementing rate limiting and monitoring to mitigate the impact of potential denial of service attacks.
Configuration hardening, such as disabling URL encoding when not needed, can also help reduce the risk associated with this vulnerability. Organizations are encouraged to conduct regular security assessments to identify and address vulnerabilities before exploitation can occur.
For further support, organizations may consider engaging in penetration testing services to evaluate their security posture.
Detection Guidance
To detect potential exploitation attempts, organizations should monitor logs for unusual patterns of requests to the body-parser middleware, particularly those that exhibit high volumes of URL-encoded data. Anomalies in traffic patterns may indicate an ongoing denial of service attack.
Behavioral anomalies, such as sudden spikes in resource usage or server response times, should also be closely monitored. Network signatures that match known attack patterns can help identify and mitigate threats proactively.
AppSecure Threat Intelligence Insight
The long-term significance of CVE-2024-45590 lies in its representation of the broader threat landscape within open-source components. As reliance on third-party libraries continues to grow, vulnerabilities like this emphasize the need for robust dependency management and regular updates.
This vulnerability serves as a reminder for security teams to implement comprehensive monitoring and alerting mechanisms to quickly detect and respond to potential threats. Organizations should foster a culture of security awareness to ensure that all team members understand the implications of using third-party software.
For organizations seeking to enhance their security posture, engaging in targeted penetration testing efforts, alongside regular security assessments, can provide valuable insights into vulnerabilities and enhance defenses against attacks.
Additionally, organizations can learn from past incidents and adapt their security strategies to address emerging threats. By leveraging insights from threat intelligence, they can stay ahead of potential risks and ensure the resilience of their applications.
