Security Advisory Description

When a BIG-IP Advanced WAF/ASM security policy is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization. (CVE-2024-21789)

Impact

System performance can degrade until the bd 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.
