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. Determine if IBM Tivoli Storage Manager FastBack is installed
    Check the system for presence of IBM Tivoli Storage Manager FastBack server components. Look for installation directories or use system inventory tools that may list this product.
    Affected if The product is present on the system
  2. Identify the installed FastBack server version
    Use the product's built-in version reporting mechanism or check the version information in the installation directory. Common methods include running version commands or inspecting version files in the installation path.
    Affected if The installed version is 6.1.0.0 through 6.1.11.1, or any version before 6.1.12.1
  3. Verify the FastBack server service is running
    Check if the FastBack server service or process is active. This may involve checking running services on Windows or processes on Linux/Unix systems.
