CVE-2024-52317 is a medium-severity vulnerability affecting Apache Tomcat versions from 11.0.0-M23 through 11.0.0-M26, 10.1.27 through 10.1.30, and 9.0.92 through 9.0.95. This vulnerability allows incorrect recycling of the request and response objects used by HTTP/2 requests, which could lead to request and/or response mix-ups between users. The potential for user data exposure makes this a significant concern for organizations utilizing these versions of Tomcat.
The severity level of this vulnerability is classified as medium, with a CVSS score of 6.5. Organizations should assess the risk to their systems and prioritize patching accordingly. The urgency for defenders is moderate, as the potential for exploitation exists, but it is not highly publicized or widely known.
Users are recommended to upgrade to version 11.0.0, 10.1.31, or 9.0.96, which include fixes for this issue. Organizations should implement this patch as part of their regular update cycle to mitigate the risk associated with this vulnerability.
As of now, there is a known exploit available for this vulnerability, which increases the risk to organizations that have not yet applied the necessary updates. Organizations should remain vigilant and monitor their systems for any unusual behavior related to this vulnerability.
In conclusion, CVE-2024-52317 represents a significant risk due to its potential for request and response mix-ups, leading to data exposure. Organizations using affected versions of Apache Tomcat should take immediate action to update their systems.
Vulnerability Details
This vulnerability allows incorrect recycling of the request and response used by HTTP/2 requests, leading to request and/or response mix-up between users. The affected versions include Apache Tomcat from 11.0.0-M23 through 11.0.0-M26, from 10.1.27 through 10.1.30, and from 9.0.92 through 9.0.95. Users should upgrade to version 11.0.0, 10.1.31, or 9.0.96, which addresses the issue.
Technical Analysis
The root cause of this vulnerability is the incorrect recycling of HTTP/2 request and response objects. This allows for data from one user to potentially be exposed to another user, leading to a mix-up of requests and responses. The attack vector is network-based, and the complexity is low, as no special privileges or user interaction is required. The potential impact includes low confidentiality and integrity impacts, while availability is not affected.
Risk & Impact Analysis
Risk to organizations includes potential data exposure due to request and response mix-ups. The blast radius could be significant, especially for applications handling sensitive information through HTTP/2. Given the CVSS score of 6.5, organizations should schedule remediation within their patch management cycles.

Affected Versions
Affected versions of Apache Tomcat include: 11.0.0-M23 to 11.0.0-M26, 10.1.27 to 10.1.30, and 9.0.92 to 9.0.95. Users should upgrade to 11.0.0, 10.1.31, or 9.0.96 to mitigate the risk.
Mitigation & Remediation
Organizations should prioritize patching to versions 11.0.0, 10.1.31, or 9.0.96 as soon as possible. For those unable to immediately patch, consider implementing network controls to limit access to affected systems and monitor for unusual activity related to HTTP/2 requests. Regular security assessments, including penetration testing, can also help identify potential vulnerabilities before they are exploited.
Detection Guidance
Organizations should monitor logs for anomalies related to HTTP/2 requests. Look for unusual patterns that could indicate request and response mix-ups, such as multiple users accessing the same session data. Additionally, implement network signatures that can help identify when the vulnerability is being exploited.
