CVE-2025-30418
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 memory corruption vulnerability due to an out of bounds write in CheckPins() when using the SymbolEditor in NI Circuit Design Suite. This vulnerability may result in information disclosure or arbitrary code execution. Successful exploitation requires an attacker to get a user to open a specially crafted .sym file. This vulnerability affects NI Circuit Design Suite 14.3.0 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 confidenceA memory corruption vulnerability exists in the CheckPins() function within the SymbolEditor component of NI Circuit Design Suite. The flaw is caused by an out-of-bounds write when processing specially crafted .sym files. Successful exploitation can lead to information disclosure or arbitrary code execution.

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.
-
Confirm NI Circuit Design Suite installationCheck system for installed NI Circuit Design Suite software. Look for National Instruments or NI Circuit Design Suite in installed programs list via Control Panel or system inventory tools.Affected if NI Circuit Design Suite is present on the system
-
Identify installed versionLocate the NI Circuit Design Suite installation and determine the exact version number. This is typically found in the software's About section, registry entries under HKEY_LOCAL_MACHINE\SOFTWARE\National Instruments, or the program's executable properties.Affected if Installed version is lower than 14.3.1 (e.g., 14.0, 14.1, 14.2, or any version below 14.3.1)
-
Verify SymbolEditor component presenceConfirm the SymbolEditor component is available. This component is part of the suite and handles .sym file processing. Check for symbol editor related executables or DLLs in the NI installation directory.Affected if SymbolEditor component exists and can process .sym files
-
Check for .sym file handling capabilityDetermine whether the software can open or process .sym symbol library files. This is the attack vector - users must be able to load specially crafted .sym files into the SymbolEditor.Affected if Users can open .sym files through the SymbolEditor component
User is affected if NI Circuit Design Suite version 14.3.1 or higher is NOT installed AND the SymbolEditor can process .sym files.

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 · scoped14.3.1
Apply the vendor patch when released and implement controls to prevent users from opening untrusted .sym files until the update is available.
NI Circuit Design Suite 14.3.1
- Upgrade NI Circuit Design Suite to version 14.3.1 or later
- Verify the upgrade by checking Help > About in the application
- Exercise caution when opening .sym files from untrusted sources
- Consider implementing file validation policies for .sym files in your organization
