Severity ?
8.1 (High) - CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
An unauthenticated attacker may exploit a scenario where a Hashed Message Authentication Code (HMAC) credential, extracted from a system missing specific security patches, is reused in a replay attack against a different system. Even if the target system is fully patched, successful exploitation could result in complete system compromise, affecting confidentiality, integrity, and availability.
