Alpine Linux fixes SSH flaw that can expose passwordless accounts in some setups
Alpine Linux shipped fixed OpenSSH packages for a bug that can let attackers enter passwordless accounts if password logins are enabled and another local account has a qualifying hash. The service must also be restarted.

Researcher: *sshole, a decade-old OpenSSH flaw, lets attackers use a password of 256+ characters to log into passwordless accounts on some musl Linux systems (Lawrence Abrams/BleepingComputer)

Worth flagging the scope: it needs musl plus OpenSSH without PAM and a passwordless account, so it is not every Linux box. But Alpine is everywhere in containers, so check the base image, not just the host.

Alpine Linux SSH gets an easy backdoor

A decade-old vulnerability allows passwordless SSH login on specific Alpine Linux configurations by entering over 256 characters as a password. Alpine maintainers confirmed it's a "one connection" exploit.

OpenSSH Flaw Enables Passwordless Logins on Alpine Linux

A flaw in OpenSSH can let attackers log in to passwordless accounts on certain Alpine Linux and other musl-based systems. OpenSSH 10.6p2 and Alpine packages now fix the issue.

#Passwordless registration flows are great until your not very computer savvy neighbor sign themselves up for a service with monthly charges and no one has a clue about how to cancel the shit because we don't even know the account ID, we only see the charges on the bank

incredibly funny vulnerability

basically, musl crypt() doesn’t support passwords bigger than 256 characters for DoS-prevention reasons. if it runs into one of them it returns “\*” as its hash

the problem is that “\*” is the placeholder hash for passwordless accounts
the industry that brought you "4 is a perfectly good secret prime number, right?" has now innovated with "hey, if an account has no password set (so no one can log in), any password longer than 256 characters means you can log into it, right?"

Fact or Fiction: Passkeys can't be phished.

Mostly fact. A passkey is bound to the real site, so a fake login page has nothing to steal. Passwordless works best when the whole access journey is protected, not just the login screen.

a decade-old ssh edge case that turns a long password into a login on passwordless accounts is a boundary bug. the fix is rejecting the overflow path before auth, not hoping clients never send it.

thankfully it’s only vulnerable under a limited set of circumstances (musl, openssh, no PAM, password auth enabled for at least one account, passwordless root account)

unfortunately those circumstances include “the default Alpine Linux images for Azure and AWS”
