K17542533 : BIG-IP Advanced WAF and ASM vulnerability CVE-2023-23552

Security Advisory Description

When a BIG-IP Advanced WAF or BIG-IP ASM security policy is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization. (CVE-2023-23552)

Impact

System performance can degrade until the Traffic Management Microkernel (TMM) process is either forced to restart or is manually restarted. This vulnerability allows a remote, unauthenticated attacker to cause a degradation of service that can lead to a denial-of-service (DoS) on the BIG-IP system. There is no control plane exposure; this is a data plane issue only.
