CVE-2019-19802
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 · uneditedIn Gallagher Command Centre Server v8.10 prior to v8.10.1134(MR4), v8.00 prior to v8.00.1161(MR5), v7.90 prior to v7.90.991(MR5), v7.80 prior to v7.80.960(MR2) and v7.70 or earlier, an authenticated user connecting to OPCUA can view all data that would be replicated in a multi-server setup without privilege checks being applied.
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 confidenceThis is an authorization bypass vulnerability in Gallagher Command Centre Server where authenticated OPCUA users can view all data that would be replicated in a multi-server setup. The issue stems from missing privilege checks being applied when users connect via OPCUA, allowing unauthorized access to sensitive data that should be restricted based on user permissions.

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 checksWork through these to decide whether this CVE applies to you.
-
Identify installed Gallagher Command Centre versionRun 'gcc --version' or check the Gallagher Command Centre Server About dialog in the application. On Windows, you may also check the installed program version via Control Panel > Programs and Features.Affected if The installed version falls within any of these ranges: < 7.70, >= 7.80 and < 7.80.960, >= 7.90 and < 7.90.991, >= 8.00 and < 8.00.1161, >= 8.10 and < 8.10.1134.
-
Verify OPCUA interface is enabledCheck the Gallagher Command Centre Server configuration for OPCUA settings. This is typically found in Server Admin > Hardware > Controllers > OPCUA or via the server configuration file (usually in the Command Centre installation directory under config or settings).Affected if The OPCUA interface is enabled and accessible on the server.
-
Confirm multi-server replication is configuredInspect the Command Centre multi-server settings via Server Admin > Multi-Server or check the database configuration for replication settings. Look for configurations indicating data replication between multiple Command Centre servers.Affected if The environment uses or is configured to use multi-server replication or data synchronization between Gallagher Command Centre servers.
-
Check OPCUA user authentication settingsReview OPCUA client connection settings and authenticated users in Server Admin > Users > OPCUA Users or examine the OPCUA endpoint configuration for the authentication method in use.Affected if Users are connecting to the Command Centre Server via OPCUA protocol with authenticated access.
If the installed version is vulnerable AND OPCUA is enabled AND multi-server replication is configured, the environment is affected by this authorization bypass vulnerability.
