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
Files or directories accessible to external parties vulnerability in ABB T-MAC Plus. This issue affects T-MAC Plus: 4.0-24.

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

An information disclosure vulnerability in ABB T-MAC Plus allows unauthorized external access to files or directories. This likely represents a path traversal, directory listing, or insecure file serving configuration that exposes sensitive system files to unauthenticated network attackers. The CRITICAL 9.9 CVSS indicates network-exploitable exposure with no authentication required.

MitigationRestrict web server configuration to prevent unauthorized file/directory access, implement proper authentication and authorization controls, and update to a patched version if available beyond 4.0-24.

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 installed T-MAC Plus version
    Locate the T-MAC Plus installation directory and check the version information file, or use the application's About/Version dialog if accessible through the client interface. Common locations include the program installation folder or registry entries for installed software.
    Affected if The installed version is 4.0-24 or any version prior to the patched release (version number less than 4.0-24 in the 4.0.x series).
  2. Determine if the T-MAC Plus web interface is enabled
    Check the T-MAC Plus configuration files or service settings for web server or HTTP service status. Look for configuration parameters that enable the web-based management interface or API endpoints.
    Affected if The web interface or HTTP-based service is enabled and running on the affected system.
  3. Verify network exposure of the T-MAC Plus service
    Review network binding configurations and firewall rules to determine which network interfaces the T-MAC Plus service listens on. Use netstat or equivalent to identify listening ports associated with T-MAC Plus.
    Affected if The T-MAC Plus service is bound to a non-local interface or is accessible from networks other than trusted management subnets.
  4. Inspect access control configuration
    Examine T-MAC Plus configuration files for authentication settings, IP allowlists, or access control lists that restrict access to the management interface. Check for any anonymous or unauthenticated access permissions.
    Affected if No IP-based access restrictions are configured, or anonymous access to file/directory features is permitted.

You are affected if T-MAC Plus version 4.0-24 is installed and the web or network interface is accessible to untrusted external parties without proper access controls.
