@GossiTheDog I hope nobody is still misled by the pre-correction CVE into thinking that this is just a 'mitigate by controlling access to management interface like you should probably do anyway' thing that they can just defer to lower priority maintenance.
Relatively severe either way; but that teensy little correction was not loud enough for how dramatically an otherwise plausible mitigation turned out to be useless.
