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
Loftware Spectrum before 4.6 HF14 has Missing Authentication for a Critical Function.

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

Loftware Spectrum before version 4.6 HF14 contains a critical authentication bypass vulnerability where a specific function lacks proper authentication controls. The flaw is remotely exploitable without credentials, potentially allowing unauthenticated attackers to access sensitive labeling operations or system functions.

MitigationApply Loftware Spectrum version 4.6 HF14 or later which includes the authentication fix. If immediate patching is not possible, restrict network access to Spectrum servers via firewall or VPN to limit exposure.

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. Confirm Loftware Spectrum is installed
    Check for Loftware Spectrum installation by looking for the Spectrum service or process running on the system. On Windows, check Services for 'Spectrum' or related processes. On Linux, check for running processes named 'spectrum' or related services.
    Affected if Loftware Spectrum software is found running on the system
  2. Identify the installed Loftware Spectrum version
    Access the Spectrum web management console (typically on port 8080 or 8443) and navigate to the About or System Information page to view the installed version. Alternatively, check installation logs or version files in the Spectrum installation directory.
    Affected if The version displayed is 4.6 or any version lower than 4.6 (e.g., 4.5.x, 4.0.x, etc.)
  3. Verify if HF14 hotfix is applied
    In the Spectrum web console, check the exact version string displayed (such as '4.6 HF14' or similar). If only '4.6' is shown without the HF14 designation, the hotfix is not applied.
    Affected if The version shows 4.6 without HF14 or shows a version lower than 4.6 HF14
  4. Check network exposure of Spectrum management interface
    Review firewall rules and network configuration to determine if the Spectrum web management ports (default 8080, 8443, or custom ports) are exposed to untrusted networks or the internet. Use netstat or similar tools to identify listening interfaces.
    Affected if The Spectrum management interface is accessible from untrusted networks or directly from the internet

If Loftware Spectrum is installed and the version is 4.6 or lower without the HF14 hotfix, and the management interface is network-accessible, the system is affected by this vulnerability.

dbcve · scoped
Upgrade available Upgrade to 4.6 or later
Fixed in 4.6
Interim mitigation

Apply Loftware Spectrum version 4.6 HF14 or later which includes the authentication fix. If immediate patching is not possible, restrict network access to Spectrum servers via firewall or VPN to limit exposure.

Recommended fix Moderate confidence

Loftware Spectrum 4.6 HF14 (Hotfix 14) or later

  1. 1. Identify the current Loftware Spectrum version in your environment
  2. 2. If running Spectrum version < 4.6 or = 4.6, plan for upgrade
  3. 3. Contact Loftware support or access their official download portal to obtain version 4.6 HF14 (Hotfix 14) or later
  4. 4. Review Loftware upgrade documentation for prerequisites and backup procedures
  5. 5. Apply the upgrade in a test environment before production deployment
  6. 6. Deploy the upgrade to production following standard change management procedures
  7. 7. Verify the installation and confirm the version shows 4.6 HF14 or higher
