CVE-2003-1562 (GCVE-0-2003-1562)

Vulnerability from cvelistv5 – Published: 2008-08-04 10:00 – Updated: 2024-09-16 19:56
VLAI
Summary
sshd in OpenSSH 3.6.1p2 and earlier, when PermitRootLogin is disabled and using PAM keyboard-interactive authentication, does not insert a delay after a root login attempt with the correct password, which makes it easier for remote attackers to use timing differences to determine if the password step of a multi-step authentication is successful, a different vulnerability than CVE-2003-0190.
