Name of the Vulnerable Software and Affected Versions F5 BIG-IP ASM versions 11.6.1 through 11.6.5.1

Description The issue occurs when the BIG-IP system sends data plane traffic to back-end servers unencrypted, even when a Server SSL profile is applied, under certain configurations.

Recommendations For versions 11.6.1 through 11.6.5.1, ensure that the Server SSL profile is correctly configured to encrypt data plane traffic to back-end servers.
