CVE-2017-6129 is a vulnerability of currently unknown severity. In F5 BIG-IP APM software version 13.0.0 and 12.1.2, in some circumstances, APM tunneled VPN flows can cause a VPN/PPP connflow to be prematurely freed or cause TMM to stop responding with a "flow not in use" assertion. An attacker may be able to disrupt traffic or cause the BIG-IP system to fail over to another device in the device group.. EPSS estimates a 1.64% chance of exploitation in the next 30 days.
