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 if Tridium Niagara is installed
    Locate Niagara installation directories or check for Niagara services running on the system. Look for common installation paths like C:/Niagara or /opt/niagara, and check for running niagara.exe or similar processes.
    Affected if Tridium Niagara Framework or Niagara Enterprise Security is found on the system
  2. Determine the installed Niagara version
    Access the Niagara About page in the Workbench UI, check the version.properties or version.txt file in the installation directory, or review startup logs for version information.
    Affected if The version is 4.10u10 or earlier, 4.14u1 or earlier, or 4.15 (any 4.15.x version before 4.15.1)
  3. Verify the operating system is QNX
    Check the host operating system using commands like 'uname -a', 'systeminfo', or by inspecting system properties. The vulnerability specifically affects the QNX platform implementation.
    Affected if The Niagara Framework is running on a QNX operating system
  4. Inspect file permissions on critical system resources
    Examine permission settings on Niagara configuration directories, lib folders, and system files. Look for overly permissive access controls that may allow unauthorized file manipulation.
    Affected if Critical directories or files have permissions that allow modification by unauthorized users or processes

The system is affected if it runs Tridium Niagara Framework or Niagara Enterprise Security on QNX with version 4.10u10 or earlier, 4.14u1 or earlier, or any 4.15.x version below 4.15.1.

Mitigation available No clean upgrade yet — mitigate in the meantime
Mitigation

Upgrade Niagara Framework and Enterprise Security to versions 4.14.2u2, 4.15.u1, or 4.10u.11 as recommended by Tridium to address the permission assignment vulnerability.

Recommended fix High confidence

4.14.2u2 (for 4.14.x line) or 4.15u1 (for 4.15.x line) or 4.10u11 (for 4.10.x line)

  1. 1. Identify the currently installed Niagara Framework or Niagara Enterprise Security version using the system's about or version information panel.
  2. 2. Based on your current major version line, plan the upgrade path: if on 4.10.x, upgrade to 4.10u11; if on 4.14.x, upgrade to 4.14.2u2; if on 4.15.x, upgrade to 4.15u1.
  3. 3. Download the appropriate fixed version installer from the official Tridium/Honeywell support portal or Niagara Community documentation.
  4. 4. Review upgrade documentation for any prerequisites or migration considerations specific to your deployment.
  5. 5. Create a complete backup of the Niagara station, including all configuration files, databases, and custom modules.
  6. 6. Test the upgrade in a non-production environment first to verify compatibility with existing custom modules and integrations.
  7. 7. Schedule a maintenance window and perform the upgrade following the official installation guide.
  8. 8. After upgrade, verify that the file permission vulnerability is resolved by confirming proper permission assignments on critical system files.
Caveat Upgrading between major versions may require module compatibility verification; custom modules written for older versions may need recompilation or updates
