An authentication bypass vulnerability affecting just about every Intel server with AMT, ISM or Intel Small Business technology enabled, allowing unprivileged network attackers to gain system privileges (where AMT has been provisioned). This is notable because AMT provides the possibility to remotely control a computer even if when powered off. Packets sent to ports 16992 or 16993 are redirected through Intel’s Management Engine (a small, separate processor independent of the main CPU) and passed to AMT. Patch rollouts are expected to be slow, as while it is Intel’s responsibility to develop the patches (which it has done), it is not Intel’s responsibility to deliver them. That’s down to the device manufacturers and OEMs; and it is generally thought that not all will do so.
