Servers can be backdoored by exploiting buggy motherboard controll

Reasonable environments don't allow BMC access from the normal LAN, and instead have a protected LAN segment for the BMC's NIC, so the risk typically minimal as it requires breaching a secure control network. It's bad to have insecure hardware, but defense-in-depth and proper network design makes compromise from it much more unlikely.

There is a a server I have whose host provides a VPN for customers onto the BMC network. I don't know if they are checking which IP address I access through the VPN, and I don't really want to find out lest I get terminated.

There's another one from a host that just has it open to the internet. I bet you'd find a bunch by scanning the internet.
