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

Noroxi assessment

Priority: Monitor (action score 24/100)

  • The sources we track (CISA KEV, Exploit-DB, Metasploit, Nuclei, GitHub) show no public exploit code or exploitation in the wild.
  • Probability of exploitation in the next 30 days: 0.17% (FIRST EPSS).
  • Physical access to the device is required. No account or password is required. No user action is required. No special conditions are required; it is repeatable.
  • Fixed version: F5 BIG-IP 13.1.4, 14.1.4, 15.1.1.

Low priority for now. Upgrade to F5 BIG-IP 13.1.4, 14.1.4, 15.1.1 or later.

Generated automatically from the record's data: CVSS (NVD and CNA), CISA KEV and SSVC, FIRST EPSS, exploit sources, fixed versions. How we calculate it

Primary sources: NVD · CVE.org · FIRST EPSS

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.

Exploit status

No known public exploit

No public exploit has been observed yet. That doesn't mean you're safe, only that the bar is a little higher.

Research context

For pentesters and researchers: attack profile, score disagreement, timeline, patch commits, credits, variant and chain candidates, bug bounty scope. All derived from existing data; no exploit code.

Variant candidates

Same product, same weakness class, within 18 months. If the patch missed the root cause, the sibling bug is here.
