Last modified
CVE-2019-6654 is a medium-severity vulnerability rated 4.3/10 on the CVSS scale. 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.. EPSS estimates a 0.48% chance of exploitation in the next 30 days.
Description
