QID 376700: F5 BIG-IP Application Security Manager (ASM), Local Traffic Manager (LTM), Access Policy Manager (APM) BIG-IP SIP ALG Profile Vulnerability (K51539421)

F5 BIG-IP ASM (Application Security Manager) is a flexible web application firewall that secures web applications in traditional, virtual, and private cloud environments.
F5 BIG-IP (LTM) Local Traffic Manager is the most popular module offered on F5 Networks BiG-IP platform. The real power of the LTM is it is a Full Proxy, allowing you to augment client and server side connections. All while making informed load balancing decisions on availability, performance, and persistence.
F5 BIG-IP Access Policy Manager (APM) is a secure, flexible, high-performance solution that provides unified global access to your network, cloud, and applications.

When a Session Initiation Protocol (SIP) message routing framework (MRF) application layer gateway (ALG) profile is configured on a Message Routing virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. (CVE-2022-26370)
