MEDIUM 4.3EPSS 0.48%

Does this matter?

Lower severity and a low EPSS score (0.48%). Track it; it rarely justifies an emergency change on its own.

Description

On versions 14.0.0-14.1.2, 13.0.0-13.1.3, 12.1.0-12.1.5, and 11.5.1-11.6.5, the BIG-IP system fails to perform Martian Address Filtering (As defined in RFC 1812 section 5.3.7) on the control plane (management interface). This may allow attackers on an adjacent system to force BIG-IP into processing packets with spoofed source addresses.
