Last modified

CVE-2003-1562 is a vulnerability of currently unknown severity. 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.. EPSS estimates a 5.57% chance of exploitation in the next 30 days.
