(also BMC)

Baseboard management controller definition

A baseboard management controller is a small specialized processor on a server's, network’s, or computer’s motherboard. With graphics and controls built in, it is used to monitor and manage the system remotely. It saves time and resources because system administrators no longer have to be physically present. Connecting to the system remotely allows them to check the power cycle and temperatures, install and update firmware, and get instant notifications whenever there’s a failure in the system.

Baseboard management controller security concerns

  • Attackers can exploit the AnywhereUSB vulnerability and connect to the system remotely. It allows them to mount a USB device and create a back door for further remote access through the internet.
  • Pantsdown is another vulnerability that allows attackers to install malware on the system.
