The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the K42378447 advisory.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.

"The version of F5 Networks BIG-IP installed on the remote host is prior to tested version. It is, therefore, affected by
a vulnerability as referenced in the K42378447 advisory.
- The Internet Key Exchange v1 main mode is vulnerable to offline dictionary or brute force attacks. Reusing
a key pair across different versions and modes of IKE could lead to cross-protocol authentication
bypasses. It is well known, that the aggressive mode of IKEv1 PSK is vulnerable to offline dictionary or
brute force attacks. For the main mode, however, only an online attack against PSK authentication was
thought to be feasible. This vulnerability could allow an attacker to recover a weak Pre-Shared Key or
enable the impersonation of a victim host or network. (CVE-2018-5389)
