CVE-2019-6654
4.3 · MEDIUMOverview
CVE-2019-6654 is a medium-severity vulnerability affecting f5 big-ip_local_traffic_manager. It was published on September 25, 2019 and has a CVSS 3.1 base score of 4.3 (MEDIUM).
This vulnerability has a CVSS 3.1 base score of 4.3, rated MEDIUM. It requires local or adjacent network access to exploit. No authentication or special privileges are required for exploitation.
Technical 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.
Remediation
Check the references section for vendor advisories and patches from f5. Update big-ip_local_traffic_manager to the latest patched version. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
