Os Release
· BIG-IP Series
Is BIG-IP 13.1 still maintained?
No. F5 Networks no longer maintains BIG-IP 13.1; support ended 2023-12-31. It receives no fixes of any kind, including security patches. Devices running it are unpatched against any newer vulnerability — plan an upgrade to a maintained release. See F5 Networks's lifecycle bulletin.
When do security fixes for BIG-IP 13.1 stop?
Engineering fixes for BIG-IP 13.1 — including security patches — stop on 2022-12-31. After that date, a device on this release cannot be patched against newly disclosed vulnerabilities without upgrading, which is the point that matters for KEV exposure and compliance.
What should I upgrade BIG-IP 13.1 to?
Upgrade to a currently maintained F5 Networks release. Check the release-train table on the vendor page for the nearest supported version.
What known-exploited CVEs apply to the BIG-IP 13.1 past end of support?
6 CVEs in CISA's Known Exploited Vulnerabilities catalog affect F5 Networks BIG-IP. Because BIG-IP 13.1 is past end of engineering, it will not receive fixes for them — a device left on this release is exploitable with no patch available. Upgrade to a maintained release. See the Known Exploited Vulnerabilities table below for the full list.
Known Exploited Vulnerabilities
This device is past F5 Networks's security-support date. 6 CVEs in CISA's Known Exploited Vulnerabilities catalog apply to the platform it runs. F5 Networks is not issuing patches for this model. Isolate, compensate, or refresh.

Source: CISA Known Exploited Vulnerabilities catalog. The Ransomware flag reflects CISA's own knownRansomwareCampaignUse field, set when the CVE has been observed in ransomware campaigns per their threat intel. It's not a property of the vulnerability description itself.
Correlation is at the platform level, not per-OS-version. Not exhaustive: KEV only lists actively-exploited CVEs and many relevant unexploited vulnerabilities are not here. Verify against vendor security advisories (PSIRT, JSA, PAN-SA) and NVD before acting. See compensating controls if refresh isn't immediate.
BIG-IP 13.1 Release Lifecycle
BIG-IP 13.1 is a F5 Networks BIG-IP software release. Releases are maintained on a fixed schedule: F5 Networks ships fixes and security patches until the release reaches end of engineering, after which a device must be upgraded to a maintained release to stay patchable. The dates below are milestones for the software train, not for any specific appliance — hardware running this release has its own separate lifecycle. This product has reached end of life as of , meaning F5 Networks no longer provides technical support, software updates, or hardware replacement for this product. Organizations still running the BIG-IP 13.1 should plan a migration .
