Vulnerabilidades do F5 Big-ip Next Cloud-native Network Functions

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.

When an HTTP/2 profile and an iRule containing the HTTP::redirect or HTTP::respond command are configured on a virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) process to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When a classification profile is configured on a UDP virtual server, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When SSL profiles are configured on a virtual server, undisclosed traffic can cause the virtual server to stop processing new client connections.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When an SSL profile is configured on a virtual server on BIG-IP Virtual Edition (VE) without Intel QuickAssist Technology (QAT) or on BIG-IP hardware platforms with the database variable crypto.hwacceleration set to disabled, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When using a multi-bladed platform with more than one blade, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When IPsec is configured on the BIG-IP system, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When a client SSL profile is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When Diffie-Hellman (DH) group Elliptic Curve Cryptography (ECC) Brainpool curves are configured in an SSL profile's Cipher Rule or Cipher Group, and that profile is applied to a virtual server, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When DNS cache is configured on a BIG-IP or BIG-IP Next CNF virtual server, undisclosed DNS queries can cause an increase in memory resource utilization.   Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When HTTP/2 Ingress is configured, undisclosed traffic can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When a classification profile is configured on a virtual server without an HTTP or HTTP/2 profile, undisclosed requests can cause the Traffic Management Microkernel (TMM) to terminate. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When a TCP profile with Multipath TCP (MPTCP) enabled is configured on a virtual server, undisclosed traffic along with conditions beyond the attacker's control can cause the Traffic Management Microkernel (TMM) to terminate.  Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.

When an iRule containing the HTTP::respond command is configured on a virtual server, undisclosed requests can cause an increase in memory resource utilization. Note: Software versions which have reached End of Technical Support (EoTS) are not evaluated.
