Wow. A _remotely_ exploitable Intel firmware vulnerability? You don't see one of those every day. My instinctive reaction is that this is ridiculously serious, although I'd need to see the full technical details.
It's worth noting that the reference to "system privileges" being attained likely refers to something much more privileged than we would normally ascribe to "system privileges". Normally, "system privileges" would mean something SYSTEM on Windows or root on Linux. In the event of "system privileges" in the management component, remember that the main CPU is a slave to this thing.
