CVE-2024-23306

Sensitive-file access by local low-privileged users

Published Feb 14, 2024 · Updated Aug 28, 2025

Insufficiently protected credentials in F5 BIG-IP Next CNF before 1.2.0 and SPK before 1.5.0 allow local users to access sensitive files. F5 has not disclosed the affected component or the operation that exposes the files, so the exact mechanism and file paths remain unknown. Exploitation requires low privileges and local access to a CNF or SPK system; successful use permits sensitive-file access and integrity impact without a reported service interruption.
