Severity: 3-Major


If there are HTTPS monitor objects that were created using BIG-IP software v12.x, when the BIG-IP is upgraded directly to v14.0.0 or later, the operation automatically creates server SSL profiles for the HTTPS monitors as needed. Those server SSL profile objects do not have 'no-tlsv1.3' included in their 'options' configuration.


TLSv1.3 gets enabled on the server SSL profiles.


-- Having HTTPS monitors configured in v12.x before upgrading. -- Directly upgrading from v12.x to v14.0.0 or later


-- To avoid this issue, upgrade from v12.x to v13.x, and then upgrade to v14.0.0 or later -- To mitigate this issue, modify the affected profile to disable TLSv1.3.
