CVE-2025-2630
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 · uneditedThere is a DLL hijacking vulnerability due to an uncontrolled search path that exists in NI LabVIEW. This vulnerability may result in arbitrary code execution. Successful exploitation requires an attacker to insert a malicious DLL into the uncontrolled search path. This vulnerability affects NI LabVIEW 2025 Q1 and prior versions.
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 confidenceDLL hijacking vulnerability in NI LabVIEW where an uncontrolled search path allows attackers to place malicious DLLs that get loaded by the application, leading to arbitrary code execution. The attacker must insert a malicious DLL into the uncontrolled search path for the application to load it.

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 LabVIEW versionOpen LabVIEW and go to Help > About LabVIEW, or check the executable properties (right-click on LabVIEW.exe > Properties > Details). Compare the version number to the affected list: <= 2021, 2022, 2023, 2024, or 2025.Affected if The installed version is any of 2021 (or earlier), 2022, 2023, 2024, or 2025.
-
Check DLL search path orderingRun the application with a debugging tool or Process Monitor (Sysinternals) to capture DLL loading behavior. Look for DLLs being loaded from directories writable by standard users (e.g., the application working directory, current directory, or subdirectories).Affected if DLLs are being loaded from directories that are not secure system paths (e.g., Windows\System32).
-
Verify working directory ownershipCheck if the LabVIEW application is launched from or runs in a directory where unprivileged users can write files (e.g., shared folders, user home directories, or network drives). Use file system permissions to confirm who has write access to the launch directory.Affected if The working directory or application directory is writable by users without elevated privileges.
-
Inspect application DLL loading behaviorUse Process Monitor to filter for LabVIEW.exe and track DLL load events. Examine the 'Result' column to identify DLLs that loaded from paths outside the secure Windows\System32 path.Affected if LabVIEW loads any DLL from its working directory, current directory, or user-writable paths instead of only from secure system directories.
You are affected if you are running any version of NI LabVIEW from 2021 through 2025 and the application loads DLLs from directories that unprivileged users can modify.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scopedEnsure the application uses secure DLL search path ordering (e.g., SetDllDirectory with empty string to remove unsafe paths, or use fully qualified paths), and update to a patched version of NI LabVIEW when available.
LabVIEW 2025 Q2 or later
- 1. Upgrade NI LabVIEW to version 2025 Q2 or later to remediate the DLL hijacking vulnerability
- 2. After upgrading, verify that no untrusted or unauthorized DLL files exist in LabVIEW installation directories and working directories
- 3. Ensure LabVIEW runs from trusted directories and avoid placing executable files in locations with weak access controls
- 4. Verify the upgrade was successful by checking the LabVIEW version (Help > About LabVIEW)
