The auth_via_key function in pam_ssh.c in pam_ssh before 1.92, when the allow_blank_passphrase option is disabled, allows remote attackers to bypass authentication restrictions and use private encryption keys requiring a blank passphrase by entering a non-blank passphrase.

Security readout for executives and security teams

Older pam_ssh versions could fail to enforce a policy that blocks SSH private keys with blank passphrases. A remote attacker could enter a non-blank passphrase and still use a blank-passphrase key, bypassing that restriction. Exposure is limited to systems using pam_ssh before 1.92 with allow_blank_passphrase disabled and SSH-key authentication paths governed by pam_ssh. Treat as a targeted legacy exposure issue. Prioritize remediation on internet-accessible or administrator-access systems that still depend on pam_ssh before 1.92. Mitigation focus: Upgrade pam_ssh to version 1.92 or later where available.; Check operating system vendor advisories for supported package fixes.; Inventory systems using pam_ssh for SSH-key based PAM authentication..
