CISA’s KEV entry confirms it has been exploited in the wild and assigns a remediation due date of 2023-11-21. No further technical specifics, such as affected versions, attack prerequisites, or impact scope, were provided in the supplied official materials, so they are not inferred here.

Defensive priority

Urgent. CISA has marked this vulnerability as known exploited and set a remediation deadline, so it should be addressed immediately using vendor mitigation guidance or by discontinuing use if mitigations are unavailable.

Recommended defensive actions

  • Review F5’s vendor guidance for CVE-2023-46748 and apply the recommended mitigations without delay.
  • If vendor mitigations are unavailable or cannot be applied promptly, discontinue use of the product as CISA advises.
  • Prioritize exposure reduction for any BIG-IP management interfaces, especially administrative access paths.
  • Validate whether your environment includes the BIG-IP Configuration Utility and track remediation to completion before the CISA due date.
  • Monitor for signs of abuse on systems running the affected component and review administrative access logs as part of incident-response hardening.

Evidence notes

This debrief is based only on the supplied official sources: the CISA Known Exploited Vulnerabilities feed entry, the official CVE record, and the NVD detail page. The corpus confirms the product, vulnerability name, KEV status, date added, and due date.
