CVE-2024-51476
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedIBM Concert Software 1.0.5 uses an inadequate account lockout setting that could allow a remote attacker to brute force account credentials.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceIBM Concert Software version 1.0.5 contains a credential brute force vulnerability due to inadequate account lockout settings. The application fails to implement proper account lockout thresholds after failed login attempts, allowing remote attackers to repeatedly guess passwords without being blocked. This is a classic CWE-307 (Improper Restriction of Excessive Authentication Attempts) vulnerability.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Confirm IBM Concert Software versionLocate and inspect the installed IBM Concert Software version. Check the product's about page, installation directory, or run: java -jar concert.jar --version or similar version command provided by the product.Affected if The installed version is 1.0.5 exactly.
-
Locate authentication configurationSearch the IBM Concert Software installation directory for configuration files related to authentication, login, or security. Common file names may include: application.properties, security-config.xml, authentication.yaml, or similar. Inspect these files for account lockout settings.Affected if Account lockout threshold is missing, set to zero, or set to an excessively high value (e.g., > 10 failed attempts).
-
Inspect login policy settingsExamine the login or authentication policy configuration within the application or its configuration files. Look for parameters such as maxFailedAttempts, lockoutThreshold, accountLockoutCount, or similar naming conventions.Affected if No lockout threshold is defined or the threshold allows unlimited failed attempts.
-
Check lockout duration configurationLook for lockout duration or account lockout time settings in the same authentication configuration files. Parameters may be named lockoutDuration, lockoutTime, accountLockoutMinutes, or similar.Affected if Lockout duration is not configured or set to zero, meaning accounts never lock out after failed attempts.
If the installed version is 1.0.5 and the authentication configuration lacks a proper account lockout threshold (typically 5-10 attempts) and duration, the environment is vulnerable to brute force attacks.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataImplement account lockout policies with a reasonable threshold (5-10 failed attempts), configure lockout duration, and enable monitoring/alerts for brute force attempts. Consider implementing multi-factor authentication as a defense-in-depth measure.
