FAUCET Score

CVE-2019-6664 describes a vulnerability in BIG-IP versions 15.0.0 and 14.1.0-14.1.0.6 where network protections on the management port do not adhere to current best practices. With a CVSS score of 7.5 (HIGH), this vulnerability is easily exploitable over the network with low complexity and no user interaction, potentially leading to high impact on integrity.
