Medium Nessus Plugin ID 118613


The remote device is missing a vendor-supplied security patch.


Undisclosed traffic patterns sent to BIG-IP virtual servers, with the TCP Fast Open and Tail Loss Probe options enabled in the associated TCP profile, may cause a disruption of service to the Traffic Management Microkernel (TMM). (CVE-2017-6136)


An attacker may be able to disrupt traffic or cause the BIG-IP system to fail over to another device in the device group.

Note : The Fast Open and the Tail Loss Probe TCP profile options are both disabled in the default configuration, and both options must be enabled to expose this vulnerability.
