An unauthenticated remote attacker may be able to disrupt services on F5 BIG-IP 11.4.1 - 11.5.4 devices with maliciously crafted network traffic. This vulnerability affects virtual servers associated with TCP profiles when the BIG-IP system's tm.tcpprogressive db variable value is set to non-default setting "enabled". The default value for the tm.tcpprogressive db variable is "negotiate". An attacker may be able to disrupt traffic or cause the BIG-IP system to fail over to another device in the device group.

Security readout for executives and security teams

CVE-2016-7468 is a denial-of-service risk in older F5 BIG-IP systems. An unauthenticated remote attacker may disrupt traffic or trigger failover, but the issue applies only to BIG-IP 11.4.1 through 11.5.4 when a specific TCP-related database variable is set to the non-default value enabled. Likely exposure is limited to legacy BIG-IP deployments in the affected version range with TCP-profile virtual servers and tm.tcpprogressive explicitly enabled. Internet-facing load balancers or high-availability pairs would carry the highest operational impact. Treat this as a targeted operational resilience issue for legacy F5 infrastructure. It is not listed as known exploited in the provided sources, but unauthenticated disruption of load-balanced services can still create meaningful outage risk. Mitigation focus: Identify any BIG-IP 11.4.1-11.5.4 systems in production.; Check F5 advisory K13053402 for vendor-approved fixes and mitigations.; Review whether tm.tcpprogressive is set to enabled..
