CVE-2023-3470

Cryptographic key access via deterministic HSM password

Published Aug 2, 2023 · Updated Oct 22, 2024

Weak credentials in F5 BIG-IP allow local users or physically proximate attackers to access FIPS HSM cryptographic keys. Affected Cavium Nitrox cards generate the Crypto User password deterministically, making the correct credential derivable. Exploitation requires authenticated TMSH or physical HSM access; on vCMP, the shared password also exposes keys belonging to other Guests.
