Hi! I would appreciate if anyone can confirm for below.

For the routers using IPSEC tunnels with ISAKMP enabled (without any IKEv2 config),  can the attacker exploit this vulnerability by sending malformed IKEv2 packets?

Both initiator and responder must have IKEv2 config to be able to trigger this vulnerability? We have many routers using IPSEC tunnels with IKEv1 and not sure whether this vulnerability is affected or not.

Thanks & Regards,

A device does not need to be configured with any IKEv2-specific features to be vulnerable?
