F5 BIG-IP Advanced Firewall Manager vulnerability analysis and mitigation

On BIG-IP version 16.0.x before 16.0.1.2, 15.1.x before 15.1.3.1, 14.1.x before 14.1.4.3, 13.1.x before 13.1.4.1, and all versions of 12.1.x, when an SCTP profile with multiple paths is configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate (MITRE CVE).

The vulnerability affects BIG-IP systems with SCTP (Stream Control Transmission Protocol) profiles configured with multiple paths on a virtual server. When specific undisclosed requests are made to the affected system, it can result in the termination of the Traffic Management Microkernel (TMM) (CERT-FR).

The primary impact of this vulnerability is a denial of service condition through the termination of the Traffic Management Microkernel (TMM), which is a critical component of the BIG-IP system (CERT-FR).

The vulnerability can be addressed by upgrading to the following versions: BIG-IP 16.0.1.2 or later, 15.1.3.1 or later, 14.1.4.3 or later, or 13.1.4.1 or later. Systems running version 12.1.x should be upgraded to a supported version as all versions of 12.1.x are affected (MITRE CVE).
