sshd in OpenSSH 3.5p1, when PermitRootLogin is disabled, immediately closes the TCP connection after a root login attempt with the correct password, but leaves the connection open after an attempt with an incorrect password, which makes it easier for remote attackers to guess the password by observing the connection state, a different vulnerability than CVE-2003-0190. NOTE: it could be argued that in most environments, this does not cross privilege boundaries without requiring leverage of a separate vulnerability.

Security readout for executives and security teams

This is an old OpenSSH information leak affecting sshd 3.5p1 behavior around blocked root logins. A remote observer could distinguish a correct root password from an incorrect one by connection behavior, making password guessing easier. Sources do not show active exploitation or a named fix. Exposure is most likely on very old systems still running OpenSSH 3.5p1, including environments matching the FreeBSD-STABLE discussion in the references. Modern maintained OpenSSH deployments are not identified as affected in the provided sources. Treat this as legacy exposure cleanup, not an emergency, unless old SSH services remain reachable. The main business risk is weak asset hygiene combined with password guessing against privileged accounts. Mitigation focus: Identify any hosts still running OpenSSH 3.5p1 or matching affected OS packages.; Check vendor or OS guidance for the appropriate fixed or supported OpenSSH package.; Retire unsupported SSH packages through normal change control..
