F5: Security Vulnerabilities
On F5 BIG-IP 13.1.0-13.1.0.3 or 13.0.0, when authenticated administrative users execute commands in the Traffic Management User Interface (TMUI), also referred to as the BIG-IP Configuration utility, restrictions on allowed commands may not be enforced.

On F5 BIG-IP versions 13.0.0 - 13.1.0.3, attackers may be able to disrupt services on the BIG-IP system with maliciously crafted client certificate. This vulnerability affects virtual servers associated with Client SSL profile which enables the use of client certificate authentication. Client certificate authentication is not enabled by default in Client SSL profile. There is no control plane exposure.

On F5 BIG-IP versions 13.0.0 - 13.1.0.3 or 12.0.0 - 12.1.3.1, TMM may restart when processing a specifically crafted page through a virtual server with an associated PEM policy that has content insertion as an action.

In some circumstances, the Traffic Management Microkernel (TMM) does not properly handle certain malformed Websockets requests/responses, which allows remote attackers to cause a denial-of-service (DoS) or possible remote code execution on the F5 BIG-IP system running versions 13.0.0 - 13.1.0.3 or 12.1.0 - 12.1.3.1.

On F5 BIG-IP versions 13.1.0 - 13.1.0.3, when ASM and AVR are both provisioned, TMM may restart while processing DNS requests when the virtual server is configured with a DNS profile and the Protocol setting is set to TCP.

On F5 BIG-IP versions 13.0.0 or 12.1.0 - 12.1.3.1, when a specifically configured virtual server receives traffic of an undisclosed nature, TMM will crash and take the configured failover action, potentially causing a denial of service. The configuration which exposes this issue is not common and in general does not work when enabled in previous versions of BIG-IP. Starting in 12.1.0, BIG-IP will crash if the configuration which exposes this issue is enabled and the virtual server receives non TCP traffic. With the fix of this issue, additional configuration validation logic has been added to prevent this configuration from being applied to a virtual server. There is only data plane exposure to this issue with a non-standard configuration. There is no control plane exposure.

Under certain conditions for F5 BIG-IP systems 13.0.0 or 12.1.0 - 12.1.3.1, using FastL4 profiles, when the Reassemble IP Fragments option is disabled (default), some specific large fragmented packets may restart the Traffic Management Microkernel (TMM).
