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
A reliance on untrusted inputs in a security decision could be exploited by a privileged user to configure the Gallagher Command Centre Diagnostics Service to use less secure communication protocols. This issue affects: Gallagher Diagnostics Service prior to v1.3.0 (distributed in 9.00.1507(MR1)).

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

This vulnerability in Gallagher Command Centre Diagnostics Service allows a privileged user to manipulate untrusted inputs to configure the service to use less secure communication protocols. The issue stems from improper security decision-making based on untrusted data, potentially exposing sensitive diagnostics communications.

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 Gallagher Command Centre version
    Locate and retrieve the installed version of Gallagher Command Centre in your environment. This is typically found in the software inventory, installed programs list, or system information about the Gallagher application.
    Affected if The installed version is 9.00 through 9.00.1506 inclusive, or exactly version 9.00.1507.
  2. Verify Diagnostics Service is installed
    Confirm the Gallagher Diagnostics Service component is present in your environment. Check the list of installed services or components associated with the Command Centre installation.
    Affected if The Diagnostics Service component is installed alongside Command Centre.
  3. Check Diagnostics Service communication protocol settings
    Examine the configuration settings for the Diagnostics Service, specifically looking for communication protocol or security-related configuration options that control how diagnostics data is transmitted.
    Affected if The Diagnostics Service is configured to allow or default to less secure communication protocols (such as unencrypted or insecure protocols) instead of secure alternatives.
  4. Review privileged user access to Diagnostics configuration
    Audit user permissions and access controls related to the Diagnostics Service configuration. Determine if unprivileged or lower-privilege users can modify the service communication settings.
    Affected if Users with elevated privileges (but not necessarily administrator-level) can modify the Diagnostics Service protocol settings without proper security validation.

You are affected if your Gallagher Command Centre version is 9.00 through 9.00.1506 or exactly 9.00.1507 AND the Diagnostics Service is configured to use less secure communication protocols that could be manipulated by privileged users.
