    I have 4 accounts on my OpenWRT router with * as their password, but I did try with a random password over 256 characters and I couldn't log into them. daemon:*:1:1:daemon:/var:/bin/false ftp:*:55:55:ftp:/home/ftp:/bin/false network:*:101:101:network:/var:/bin/false nobody:*:65534:65534:nobody:/var:/bin/false Still, this is a huge security flaw!

    Why are trying to replace the Gnu tools with non-GPL stuff again?

  • CVE-2016-6210. ask sshd about a user that doesn’t exist and it says no instantly, cause there’s nothing to hash. [The solution is] sshd grabs some other account’s salt and hashes your password anyway I’m not sure how this is relevant to what caused this bug. Seems to me like a random point that was added by the AI writing this blogpost without human review.
