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
The server in IBM Tivoli Storage Manager FastBack 6.1 before 6.1.12 allows remote attackers to execute arbitrary commands with SYSTEM privileges via unspecified vectors.

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 confidence

IBM Tivoli Storage Manager FastBack server versions prior to 6.1.12 contain a critical vulnerability allowing unauthenticated remote attackers to execute arbitrary commands with SYSTEM-level privileges. The specific attack vector and vulnerability type are not detailed in available documentation, but the CVSS score of 10 indicates a trivially exploitable flaw with complete system compromise potential.

MitigationUpgrade IBM Tivoli Storage Manager FastBack to version 6.1.12 or later. Given the critical severity and SYSTEM-level access, treat this as an emergency change requiring immediate patching and verification in a non-production environment before production deployment.

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. Identify IBM Tivoli Storage Manager FastBack installation
    Locate the FastBack server installation directory or check Windows Programs and Features for 'IBM Tivoli Storage Manager FastBack' entry. The version is typically displayed in the program name or can be found in the server's About or version information.
    Affected if The software is installed on the system
  2. Determine the installed FastBack server version
    Open the FastBack server management console or check the server's version information (commonly accessible via the server's About dialog, a version file in the installation directory, or via command line: 'fbmaster -version' or similar). Record the full version number (e.g., 6.1.11.1).
    Affected if A version number is returned that matches any of the affected versions: 6.1.0.0, 6.1.1.0, 6.1.7.2, 6.1.8.0, 6.1.8.1, 6.1.9.0, 6.1.9.1, 6.1.10.0, 6.1.10.1, 6.1.11.0, or 6.1.11.1
  3. Verify if FastBack server service is running and exposed
    Check if the FastBack server process (typically named 'FBserver' or similar) is running. Determine if the server is accessible over the network by identifying open ports associated with FastBack (commonly port 11460 or similar RPC-based ports). Use 'netstat -an' or the Windows Services console to confirm.
    Affected if The FastBack server service is running and exposed on the network, making it reachable for remote exploitation
  4. Confirm the FastBack server is accessible without authentication
    Review the FastBack server configuration to verify whether unauthenticated or anonymous access is permitted to the server's administrative interfaces or RPC endpoints.
    Affected if Unauthenticated network access to the FastBack server is allowed

If IBM Tivoli Storage Manager FastBack server is installed with a version prior to 6.1.12 and the server is running and network-accessible, the environment is affected by CVE-2015-1949 and is at critical risk.
