CVE-2025-3938
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 · uneditedMissing Cryptographic Step vulnerability in Tridium Niagara Framework on Windows, Linux, QNX, Tridium Niagara Enterprise Security on Windows, Linux, QNX allows Cryptanalysis. This issue affects Niagara Framework: before 4.14.2, before 4.15.1, before 4.10.11; Niagara Enterprise Security: before 4.14.2, before 4.15.1, before 4.10.11. Tridium recommends upgrading to Niagara Framework and Enterprise Security versions 4.14.2u2, 4.15.u1, or 4.10u.11.
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 confidenceA Missing Cryptographic Step vulnerability in Tridium Niagara Framework on Windows, Linux, and QNX allows cryptanalysis due to a flaw in the cryptographic implementation. This weakness could enable attackers to compromise encrypted data by exploiting the missing step in the encryption/decryption process.

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 if Tridium Niagara Framework is installedCheck for Niagara installation directories or running Niagara services on the system. On Windows, look in typical installation paths like C:\Niagara or check for Niagara services. On Linux/QNX, check directories like /opt/niagara or /usr/niagara.Affected if Niagara Framework is present on the system
-
Determine the installed Niagara versionLocate the version information file or use platform-specific commands. Common methods include checking a version file in the installation directory, inspecting the niagara.version property, or querying the Niagara service via command line if accessible.Affected if The installed version matches 4.10u10, 4.14u1, or 4.15
-
Check if Niagara Enterprise Security is installedIdentify if the Niagara Enterprise Security module/component is present. This may be listed in the Niagara installation, or as a separate product installation.Affected if Niagara Enterprise Security version 4.10u10, 4.14u1, or 4.15 is installed
-
Verify the operating system platformConfirm the host operating system is Windows, Linux, or QNX, as these are the affected platforms listed for this vulnerability.Affected if Running on Windows, Linux, or QNX with a vulnerable Niagara version installed
-
Identify if cryptographic features are in useReview Niagara station configuration files for encryption settings, password storage mechanisms, or security module configurations that utilize the affected cryptographic implementation.Affected if The system uses Niagara's built-in encryption for sensitive data storage or communication
A system is affected if it runs Tridium Niagara Framework or Niagara Enterprise Security version 4.10u10, 4.14u1, or 4.15 on Windows, Linux, or QNX, particularly if cryptographic features are enabled for data protection.

dbcve · scopedUpgrade Niagara Framework and Niagara Enterprise Security to versions 4.14.2u2, 4.15.u1, or 4.10u.11 as recommended by Tridium.
Upgrade to Niagara Framework/Niagara Enterprise Security 4.10u11, 4.14.2u2, or 4.15u1 (depending on your current version branch)
- 1. Identify the current Niagara Framework or Niagara Enterprise Security version by checking the system diagnostics or About section
- 2. Review the current version against the affected versions: 4.10u10, 4.14u1, and 4.15
- 3. Determine the appropriate upgrade path based on your current version branch (4.10.x, 4.14.x, or 4.15.x)
- 4. Download the corresponding fixed release: 4.10u11, 4.14.2u2, or 4.15u1 from the official Tridium/Honeywell distribution channel
- 5. Back up all Niagara configurations, databases, and custom modules before proceeding
- 6. Follow the standard Niagara upgrade procedure documented in the Niagara installation guide
- 7. After upgrade, verify the cryptographic configuration settings are properly applied
- 8. Test critical functionality to ensure the upgrade did not break existing integrations
