Summary

F5 BIG-IP LTM, AAM, AFM, Analytics, APM, ASM, DNS, GTM, Link Controller, PEM, Websafe software version 12.0.0 to 12.1.2, 11.6.0 to 11.6.1 are vulnerable to a denial of service attack when the MPTCP option is enabled on a virtual server. Data plane is vulnerable when using the MPTCP option of a TCP profile. There is no control plane exposure. An attacker may be able to disrupt services by causing TMM to restart hence temporarily failing to process traffic.
