Fixed In:
14.1.4, 13.1.4

Opened: Jun 17, 2019
Severity: 3-Major

Symptoms

On a single virtual server, when 'TLS Renegotiation' is enabled in an associated Client SSL profile, the system should prevent enabling the 'Enforce TLS Requirements' option in the associated HTTP/2 profile.

Impact

The configuration will not load if saved.

Conditions

BIG-IP system validation does not prevent this configuration in the following scenario: 1. Disable the 'Enforce TLS Requirements' option in the HTTP/2 profile. 2. Enable 'TLS Renegotiation' in the Client SSL profile. 3. Enable the 'Enforce TLS Requirements' option in the HTTP/2 profile.

Workaround

If enabling 'Enforce TLS Requirements' in a HTTP/2 profile configured on a virtual server, ensure that 'TLS Renegotiation' is disabled in the Client SSL profile(s) on that virtual server.

Fix Information

Added a missing validation check for TLS Renegotiation and Enforce TLS Requirements.
