CVE-2023-22960Network attack vector

Credential compromise via account-lockout bypass

Published Jan 23, 2023 · Updated Apr 2, 2025

Authentication lockout bypass in Lexmark device firmware allows remote attackers to guess local-account credentials without attempt limits. The local-account lockout control fails to enforce the configured failed-attempt threshold and lockout interval, permitting unrestricted credential guesses. The affected device must expose its login interface, and successful guessing compromises credentials for the targeted local account.
