Synopsis

The remote device is missing a vendor-supplied security patch.

Description

The version of F5 Networks BIG-IP installed on the remote host is prior to 13.1.3.5 / 14.1.3.1 / 15.1.1 / 16.0.0. It is, therefore, affected by a vulnerability as referenced in the K76518456 advisory.

Note: Software versions which have reached End of Software Development (EoSD) are not evaluated. (CVE-2021-22983)
