Ah, I think it’s like “keep track of 7 items, the 8th might push something else out” ( https://en.m.wikipedia.org/wiki/The_Magical_Number_Seven,_Plus_or_Minus_Two ).
So like mind-map-complexity.
Like, when you are trying to figure out some bullshit OOP inheritance, you are 9 levels deep and have no idea what the original problem was, but you feel like you have made a connection to the solution, but now you have to backtrack everything (or figure out where your last edit was) to try and figure out what that connection actually means and what you have to do now
If your windows computer makes an outbound connection to a server that is actively exploiting this, then yes: you will suffer.
But having a windows computer that is chilling behind a network firewall that is only forwarding established ipv6 traffic (like 99.9999% of default routers/firewalls), then you are extremely extremely ultra unlucky to be hit by this (or, you are such a high value target that it’s likely government level exploits). Or, you are an idiot visiting dogdy websites or running dodgy software.
Once a device on a local network has been successfully exploited for the RCE to actually gain useful code execution, then yes: the rest of your network is likely compromised.
Classic security in layers. Isolatation/layering of risky devices (that’s why my homelab is on a different vlan than my home network).
And even if you don’t realise your windows desktop has been exploited (I really doubt that this is a clean exploit, you would probably notice a few BSOD before they figure out how to backdoor), it then has to actually exploit your servers.
Even if they turn your desktop into a botnet node, that will very quickly be cleaned out by windows defender.
And I doubt that any attacker will have time to actually turn this into a useful and widespread exploit, except in targeting high value targets (which none of us here are. Any nation state equivalent of the US DoD isn’t lurking on Lemmy).
It comes back to: why are you running windows as a server?
ETA:
The possibility that high value targets are exposing windows servers on IPv6 via public addresses is what makes this CVE so high.
Sensible people and sensible companies will be using Linux.
Sensible people and sensible companies will be very closely monitoring what’s going on with windows servers exposed by ipv6.
This isn’t an “ipv6 exploit”. This is a windows exploit. Of which there have been MANY!
