CVE-2024-4080
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 · uneditedA memory corruption issue due to an improper length check in LabVIEW tdcore.dll may disclose information or result in arbitrary code execution. Successful exploitation requires an attacker to provide a user with a specially crafted VI. This vulnerability affects LabVIEW 2024 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 confidenceMemory corruption vulnerability in LabVIEW's tdcore.dll due to improper length validation. An attacker can craft a malicious VI file that, when opened by a user, triggers the length check flaw leading to heap/stack corruption. This can enable information disclosure or arbitrary code execution within the context of the LabVIEW 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.
-
Check if LabVIEW is installedLook for LabVIEW in installed programs (Windows Control Panel > Programs and Features, or run 'Get-ItemProperty HKLM:\Software\Microsoft\Windows\CurrentVersion\Uninstall\* | Select-Object DisplayName' in PowerShell)Affected if LabVIEW appears in the list of installed software
-
Determine the installed LabVIEW versionCheck the program entry in Programs and Features for the version number, or look in the LabVIEW installation directory for version information (typically named after the version year such as 'LabVIEW 2020', 'LabVIEW 2021', etc.)Affected if The installed version matches 2020, 2021, 2022, 2023, or 2024 (or any version prior to/including 2020)
-
Locate the vulnerable tdcore.dll fileSearch for tdcore.dll within the LabVIEW installation directory (commonly found in the 'resource' or 'lib' subfolder of the LabVIEW installation path)Affected if The file tdcore.dll exists in the LabVIEW installation directory
-
Verify the attack surface - user file opening behaviorDetermine whether the system or users routinely open VI files from untrusted or unknown sources, or if there are recent VI files downloaded from the internetAffected if Users on this system open VI files from untrusted or unknown sources, or VI files from external/email sources have been opened recently
If LabVIEW version 2020 through 2024 is installed and users open VI files from untrusted sources, the environment is likely affected by this vulnerability.

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.
From vendor dataDo not open VI files from untrusted or unknown sources. Apply vendor patches when released by National Instruments/Emerson. Consider endpoint detection to monitor for anomalous LabVIEW process behavior.
