CVE-2025-30417 National Instruments CVE debrief

Who should care

Administrators, engineers, and security teams responsible for National Instruments Circuit Design Suite, especially in environments where SYM files may be received from outside trusted sources. ICS and engineering workstations that process vendor, partner, or email-delivered files should treat this as a priority patching item.

Technical summary

The supplied advisory describes a memory-corruption flaw in DecodeBase64() within Circuit Design Suite. The flaw is an out-of-bounds write triggered by improper input validation. The attack requires user interaction: a victim must open a specially crafted SYM file. The advisory states the impact can include arbitrary code execution. The affected product scope provided in the CSAF is National Instruments Circuit Design Suite versions <= 14.3.0, with remediation to 14.3.1 or later.

Defensive priority

High. The vulnerability is remotely reachable only through user-driven file handling, but the impact is severe and includes potential code execution. Patch promptly, especially on systems that regularly open externally sourced or untrusted SYM files.

Recommended defensive actions

• Update National Instruments Circuit Design Suite to version 14.3.1 or later.
• Restrict and scrutinize untrusted SYM files before opening them on engineering workstations.
• Use standard ICS defense-in-depth practices on affected systems, including least privilege and workstation hardening.
• Apply vendor security updates in coordination with change-management processes for OT/engineering environments.
• Monitor for unexpected file-opening workflows or user reports involving suspicious SYM attachments or downloads.
