CVE-2023-3470 BIG-IP FIPS HSM password vulnerability CVE-2023-3470

Medium 6.0 Published 2 Aug 2023 Updated 22 Oct 2024

Authenticated users or physical attackers can derive deterministic HSM passwords to access cryptographic keys across vCMP guests.

Exploited in the wild: Not known
Login needed: An administrator
Attackable: Local or same network only
Victim action needed: Not needed
Fix: None listed

What is CVE-2023-3470?

CVE-2023-3470 is a medium-severity vulnerability in F5 Big-Ip Access Policy Manager, published on 2 Aug 2023. It can only be exploited from the same machine or local network, with no action from the victim.

Official description

Specific F5 BIG-IP platforms with Cavium Nitrox FIPS HSM cards generate a deterministic password for the Crypto User account. The predictable nature of the password allows an authenticated user with TMSH access to the BIG-IP system, or anyone with physical access to the FIPS HSM, the information required to generate the correct password. On vCMP systems, all Guests share the same deterministic password, allowing those with TMSH access on one Guest to access keys of a different Guest.

The following BIG-IP hardware platforms are affected: 10350v-F, i5820-DF, i7820-DF, i15820-DF, 5250v-F, 7200v-F, 10200v-F, 6900-F, 8900-F, 11000-F, and 11050-F.

The BIG-IP rSeries r5920-DF and r10920-DF are not affected, nor does the issue affect software FIPS implementations or network HSM configurations.

Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Weakness: CWE-287, CWE-1391
