Last Modified: Dec 07, 2023

Affected Product(s):
BIG-IP LTM(all modules)

Fixed In:
17.1.0,, 16.1.3

Opened: Feb 21, 2022

Severity: 3-Major


TLS ciphersuites including RSA KEX are non-approved ciphers as per FIPS 140-3 certification standard


SSL handshake will not be successful.


- BIG-IP versions 16.1.3 and above - FIPS 140-3 license is installed on BIG-IP or its a FullBoxFIPS device. - f5-fips cipher-group is associated with SSL profiles - Connections are established using the RSA-KEX based ciphers


Create a custom cipher-group including all the required cipher strings and associate with the SSL profiles.
