Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
On F5 BIG-IP 15.1.x versions prior to 15.1.5.1, 14.1.x versions prior to 14.1.4.6, and 13.1.x versions prior to 13.1.5, when an IPSec ALG profile is configured on a virtual server, undisclosed responses can cause Traffic Management Microkernel(TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

On F5 BIG-IP, when an IPSec ALG (Application Layer Gateway) profile is configured on a virtual server, processing of undisclosed network responses can trigger a crash in the Traffic Management Microkernel (TMM), causing denial of service.

MitigationUpgrade to BIG-IP versions 15.1.5.1, 14.1.4.6, or 13.1.5 or later to resolve this vulnerability; alternatively, remove IPSec ALG profiles from virtual servers if not required.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Check BIG-IP version
    Run `tmsh show sys version` or `tmsh list sys version` to obtain the installed version.
    Affected if The version matches 13.1.0, 13.1.1, 13.1.3, 13.1.4, 13.1.5, 14.1.0, 14.1.2, 14.1.3, 14.1.4, 15.1.0, 15.1.1, or 15.1.2.
  2. Verify IPSec ALG profile exists
    Run `tmsh list /ltm profile alg` to list any configured ALG profiles.
    Affected if Any ALG profile is present in the configuration.
  3. Identify virtual servers with IPSec ALG profile
    Run `tmsh list /ltm virtual all` and inspect each virtual server for an `ipsec-alg-profile` setting, or search with `tmsh list /ltm virtual | grep -A 20 ipsec-alg`.
    Affected if A virtual server has an IPSec ALG profile explicitly assigned to it.
  4. Check for active TMM crashes
    Review TMM crash logs with `tmsh show /ltm crash` or check `/var/log/ltm` for recent crash entries matching the vulnerability timeframe.
    Affected if Recent TMM crashes are present and coincide with the vulnerable configuration.

A system is affected if it runs a vulnerable version (13.1.0-15.1.2) AND has an IPSec ALG profile assigned to any virtual server.

Generated from the published advisory. Verify against your own configuration.

Check your environment

Paste your version and any relevant configuration and it will be compared against the affected criteria above. Do not include secrets or credentials.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade to BIG-IP versions 15.1.5.1, 14.1.4.6, or 13.1.5 or later to resolve this vulnerability; alternatively, remove IPSec ALG profiles from virtual servers if not required.

Recommended fix High confidence

BIG-IP 13.1.x → 13.1.5+ (or 13.1.5.1); BIG-IP 14.1.x → 14.1.4.6+; BIG-IP 15.1.x → 15.1.5.1+

  1. Identify which BIG-IP modules have IPSec ALG profiles configured on virtual servers by reviewing virtual server configurations
  2. Schedule a maintenance window for the upgrade procedure
  3. Back up the current BIG-IP configuration using 'tmsh save sys config' or via the web UI (System > Archive > Create)
  4. For BIG-IP 13.1.x versions: upgrade to version 13.1.5 or later (13.1.5.1 recommended if available)
  5. For BIG-IP 14.1.x versions: upgrade to version 14.1.4.6 or later
  6. For BIG-IP 15.1.x versions: upgrade to version 15.1.5.1 or later
  7. After upgrade, verify TMM is running normally using 'tmsh show sys tmm-status' and confirm all virtual servers are operational
  8. Test that IPSec ALG functionality works correctly with the updated version
Caveat Review F5 release notes for any known issues or configuration changes between current and target versions before upgrading; some configurations may require adjustment after upgrade
