For many BMCs the second network port is a figment of your imagination. The BMC is capable of intercepting and injecting network frames on the host's interfaces. Just because you have the management port wired to a different VLAN or even a separate physical LAN means nothing.

- acdha 8y agoIt's true that many BMCs use the same physical network interface but that doesn't help an attacker hit it with a remote exploit. It could be relevant in the question of what could be done after compromise but for preventing that initial attack it's pretty effective.
