CVE-2020-5918: 
F5 BIG-IP Advanced Firewall Manager vulnerability analysis and mitigation

In BIG-IP versions 15.1.0-15.1.0.4, 15.0.0-15.0.1.3, 14.1.0-14.1.2.3, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1, the Traffic Management Microkernel (TMM) may stop responding when processing Stream Control Transmission Protocol (SCTP) traffic when traffic volume is high. This vulnerability affects TMM by way of a virtual server configured with an SCTP profile (CVE MITRE).

The vulnerability is related to the Traffic Management Microkernel (TMM) component of BIG-IP systems and specifically occurs when processing SCTP (Stream Control Transmission Protocol) traffic. The issue manifests when a virtual server is configured with an SCTP profile and experiences high traffic volume, potentially leading to a denial of service condition (CVE MITRE).

When exploited, this vulnerability can cause the Traffic Management Microkernel (TMM) to stop responding, potentially leading to a denial of service condition for systems processing SCTP traffic (CVE MITRE).

The vulnerability is triggered under high traffic volume conditions when processing SCTP traffic through a virtual server configured with an SCTP profile. The specific conditions required for exploitation suggest a moderate level of difficulty in exploiting this vulnerability (CVE MITRE).

F5 has released patched versions to address this vulnerability. Users should upgrade to versions newer than those listed as vulnerable: 15.1.0-15.1.0.4, 15.0.0-15.0.1.3, 14.1.0-14.1.2.3, 13.1.0-13.1.3.3, 12.1.0-12.1.5.1, and 11.6.1-11.6.5.1 (CVE MITRE).
