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 · unedited
IBM Concert Software 1.0.0 through 1.1.0 uses weaker than expected cryptographic algorithms that could allow an attacker to decrypt highly sensitive information.

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 · moderate confidence

IBM Concert Software versions 1.0.0 through 1.1.0 implements cryptographic algorithms that are weaker than industry standards, potentially allowing attackers to decrypt sensitive data that was protected using these weak algorithms.

MitigationUpgrade to a version beyond 1.1.0 that implements strong cryptographic algorithms, or if no upgrade is available, audit and replace weak crypto implementations with FIPS 140-2 compliant algorithms.

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 checks

Work through these to decide whether this CVE applies to you.

  1. Verify IBM Concert is installed
    Locate the IBM Concert installation directory or binary on the system. Common locations include /opt/ibm/concert or C:\Program Files\IBM\Concert on Windows. Use commands like 'ls /opt/ibm/concert' or check for the 'concert' executable in system PATH.
    Affected if IBM Concert is not found on the system, then it is not affected.
  2. Determine installed IBM Concert version
    Run the IBM Concert command-line tool with version flag, typically 'concert --version' or 'ibm-concert --version'. If CLI is unavailable, check for a version file in the installation directory such as version.txt or package.json.
    Affected if Unable to determine version, further investigation is required.
  3. Compare version against affected range
    Review the version output from the previous step. Parse the version number and compare against the affected range: >= 1.0.0 and < 2.0.0.
    Affected if Installed version is 1.0.0, 1.0.x, 1.1.0, or any version >= 1.0.0 and < 2.0.0.
  4. Identify sensitive data protected by IBM Concert
    Audit data stores, configuration files, and encrypted files that IBM Concert has processed or protected. Look for files or databases containing sensitive information that may have been encrypted using IBM Concert's built-in cryptographic functions.
    Affected if Sensitive data exists that was processed or protected by IBM Concert within the affected version range.

If IBM Concert version is 1.0.0 through 1.1.0 (exclusive of 2.0.0) and any sensitive data was encrypted using its cryptographic features, the environment is likely affected.

dbcve · scoped
Upgrade available Upgrade to 2.0.0 or later
Fixed in 2.0.0
Interim mitigation

Upgrade to a version beyond 1.1.0 that implements strong cryptographic algorithms, or if no upgrade is available, audit and replace weak crypto implementations with FIPS 140-2 compliant algorithms.

Recommended fix Moderate confidence

IBM Concert Software 2.0.0 or later

  1. Review IBM Concert Software release notes for version 2.0.0 to understand the cryptographic security fixes
  2. Plan and schedule the upgrade during a maintenance window
  3. Back up the current IBM Concert Software configuration and data
  4. Download IBM Concert Software version 2.0.0 or later from IBM Fix Central or authorized channels
  5. Stop IBM Concert Software services
  6. Install the version 2.0.0 upgrade following IBM's installation documentation
  7. Verify the upgrade was successful and services start correctly
  8. Validate that cryptographic configurations meet current security standards
Caveat Review IBM release notes for version 2.0.0 for any breaking changes or migration requirements
