CVE-2025-30417
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 Library!DecodeBase64() 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 · moderate confidenceAn out-of-bounds write vulnerability exists in the DecodeBase64() function within NI Circuit Design Suite's SymbolEditor library. By crafting a malicious .sym file with specially encoded data, an attacker can trigger memory corruption during Base64 decoding, potentially leading 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.
-
Verify NI Circuit Design Suite is installedLocate the NI Circuit Design Suite installation on the system using standard software inventory tools or by searching for National Instruments program directoriesAffected if The software is present on the system
-
Identify the installed versionDetermine the exact version number of the NI Circuit Design Suite installationAffected if The version is lower than 14.3.1
-
Confirm SymbolEditor component is presentVerify the SymbolEditor library or .sym file handling capability exists within the installationAffected if The SymbolEditor component is available and .sym files can be opened
-
Check for .sym file associationsInspect whether .sym files are associated with or can be opened by the installed softwareAffected if Users can open .sym files through the software
The environment is affected if NI Circuit Design Suite is installed with a version lower than 14.3.1 and the SymbolEditor library can be used to open .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
Avoid opening .sym files from untrusted sources until a vendor patch is available; consider updating to any later version once released.
NI Circuit Design Suite 14.3.1
- Download NI Circuit Design Suite version 14.3.1 from the official NI website (www.ni.com)
- Verify the installer checksum matches the official NI distribution
- Close any running instances of NI Circuit Design Suite
- Run the installer for version 14.3.1
- Follow the on-screen installation prompts to complete the upgrade
- After installation, verify the version by checking About or the software information panel
- Ensure users only open .sym files from trusted sources to mitigate social engineering vectors
