Summary

CVE-2024-52317 is a medium-severity Inadequate Encryption Strength (CWE-326) vulnerability in Apache Tomcat. Its CVSS base score is 6.5 (Medium).

Operationally, exploitation aligns with the MITRE ATT&CK technique Brute Force (T1110); ranked in the top 21% of CVEs by exploit likelihood; it is not currently listed in the CISA KEV catalog.

The strongest mitigations our analysis identified map to SC-13 (Cryptographic Protection) and SC-12 (Cryptographic Key Establishment and Management) — see the control section below for these in your framework.

Deeper analysis AI-assisted summary

Synthesised by an AI model from the NVD description and linked references — a reading aid, not an authoritative source.

Apache Tomcat contains an incorrect object recycling vulnerability affecting HTTP/2 request and response handling. The flaw impacts versions 11.0.0-M23 through 11.0.0-M26, 10.1.27 through 10.1.30, and 9.0.92 through 9.0.95, where request and response objects may be incorrectly reused across different users, resulting in potential information mixing.

An unauthenticated remote attacker can exploit the issue over the network without user interaction. Successful exploitation allows partial disclosure or modification of request and response data belonging to other users, corresponding to the reported CVSS 6.5 rating.

Apache Tomcat project advisories recommend immediate upgrade to versions 11.0.0, 10.1.31, or 9.0.96 to resolve the recycling defect. Corresponding notices appear on the Apache mailing lists, oss-security, and downstream vendor bulletins such as NetApp.

EPSS scores have remained stable near 0.21 with no material post-disclosure increase.

Mitigating Controls (NIST 800-53 r5) AI

SC-13 requires selection and implementation of specific cryptographic algorithms and key lengths, directly preventing use of inadequate encryption strength.

SC-12 governs cryptographic key establishment and management, which can enforce sufficient key sizes and thereby reduce inadequate encryption strength.
