CVE-2003-1562

OpenSSH <= 3.6.1p2 - Timing Attack via PAM Keyboard-Interactive Authentication

Title source: llm
STIX 2.1

Description

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.
