CWE-770

Description

When an HTTP/2 profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization.   Impact: System performance can degrade until the 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. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

Affected configurations

• f5 big-ip next cloud-native network functions (>= 1.1.0 < 1.4.3) • f5 big-ip next cloud-native network functions (>= 2.0.0 < 2.2.3) • f5 big-ip next cloud-native network functions 2.3.0 • f5 big-ip next for kubernetes (>= 2.0.0 < 2.2.3) • f5 big-ip next for kubernetes 2.3.0 • f5 big-ip next service proxy for kubernetes (>= 1.7.0 < 1.7.18) • f5 big-ip next service proxy for kubernetes (>= 1.8.0 <= 1.9.2) • f5 big-ip next service proxy for kubernetes (>= 2.0.0 <= 2.0.3)
