CVE-2024-51476Network attack vector

Account compromise via weak login lockout policy

Published Mar 6, 2025 · Updated Sep 1, 2025

Credential brute force in IBM Concert Software 1.0.5 allows remote attackers to obtain account access via repeated login attempts. The Standard Edition virtual-machine deployment applies weak password requirements and inadequate account-lockout settings by default, failing to sufficiently limit credential guesses. The login service is network reachable without prior privileges; successful guessing exposes information available to the compromised account.
