CVE-2024-52317
CVE-2024-52317 is a critical vulnerability in Apache Tomcat affecting versions 11.0.0-M23 to 11.0.0-M26, 10.1.27 to 10.1.30, and 9.0.92 to 9.0.95. This flaw arises from incorrect recycling of HTTP/2 request and response objects, potentially leading to data mix-up between different users. With an SVRS score of 30, while not immediately critical, the vulnerability requires monitoring and prompt patching. The vulnerability exposes the risk of sensitive information leakage between users due to request/response contamination. Upgrade to versions 11.0.0-M27, 10.1.31, or 9.0.96 to mitigate the potential for unintended data exposure. Although the CVSS score is 0, indicating no direct exploitability, the 'In The Wild' tag suggests awareness of the flaw, making patching a high priority. Addressing this object re-use issue is crucial to ensure data integrity and application security for Apache Tomcat users.
Description
CVE-2024-52317 is a vulnerability in Apache Tomcat that arises from incorrect object recycling and reuse in the handling of HTTP/2 requests. This vulnerability could lead to a request and/or response mix-up between different users, potentially exposing sensitive information or causing other security issues. The CVSS score for this vulnerability is 6.5, indicating a medium severity level. However, the SOCRadar Vulnerability Risk Score (SVRS) is 52, which is considered moderate, highlighting the potential for significant real-world impact.
Key Insights
- HTTP/2 Protocol Exploitation: The vulnerability exploits a weakness in the implementation of the HTTP/2 protocol within Apache Tomcat. This could potentially lead to attackers manipulating the request and response handling process to gain unauthorized access or intercept sensitive data.
- Potential for Data Breaches: The mix-up of requests and responses can compromise data confidentiality. An attacker could potentially access data intended for another user, leading to unauthorized access or data breaches.
- In The Wild: This vulnerability is actively being exploited in the wild, indicating that attackers are actively developing and deploying exploits to target vulnerable systems.
- Wide Impact: This vulnerability affects multiple versions of Apache Tomcat, including widely used versions such as 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 means a large number of systems could be vulnerable.
Mitigation Strategies
- Upgrade Apache Tomcat: Immediately upgrade to the latest versions of Apache Tomcat (11.0.0, 10.1.31, or 9.0.96) which address this vulnerability.
- Disable HTTP/2: As a temporary mitigation strategy, disable HTTP/2 support in Apache Tomcat, although this may impact performance.
- Implement Strong Access Controls: Enforce strong access controls and user authentication mechanisms to minimize the impact of potential data breaches.
- Regular Security Monitoring: Maintain regular security monitoring and threat intelligence feeds to detect any suspicious activity related to this vulnerability.
