Analyst Synthesis

Technical analysis, exploit verification, and patch instructions for CVE-2003-1562 impacting openbsd openssh. Evaluated with CVSS Base Score of 7.6 (UNKNOWN).

Original NVD Description

Source: NIST NVD
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.
