CVE-2025-30419 is a high-severity memory corruption vulnerability identified in the National Instruments (NI) Circuit Design Suite, specifically affecting versions 14.3.0 and earlier. The flaw arises from an out-of-bounds read in the function GetSymbolBorderRectSize() when the SymbolEditor component processes .sym files. This vulnerability is classified under CWE-125, which pertains to improper bounds checking leading to out-of-bounds read errors. Exploitation requires an attacker to convince a user to open a maliciously crafted .sym file within the SymbolEditor. Successful exploitation can lead to information disclosure or arbitrary code execution, potentially allowing an attacker to execute code with the privileges of the user running the application. The CVSS v3.1 base score is 7.8, reflecting high severity, with attack vector local (AV:L), low attack complexity (AC:L), no privileges required (PR:N), user interaction required (UI:R), unchanged scope (S:U), and high impact on confidentiality, integrity, and availability (C:H/I:H/A:H). No known exploits are currently reported in the wild, and no patches have been published yet. The vulnerability's local attack vector implies that the attacker must have some form of access to deliver the malicious file, but no prior authentication or elevated privileges are needed. The requirement for user interaction (opening the file) is a critical factor in the attack chain. Given the nature of the vulnerability, it poses a significant risk to environments where NI Circuit Design Suite is used for electronic design automation (EDA), especially in engineering and research contexts.

For European organizations, particularly those involved in electronics design, manufacturing, and research sectors, this vulnerability presents a substantial risk. Exploitation could lead to unauthorized disclosure of sensitive design data, intellectual property theft, or disruption of critical design workflows through arbitrary code execution. This could impact confidentiality by exposing proprietary circuit designs, integrity by allowing manipulation of design files or software behavior, and availability by potentially crashing the application or system. Given the specialized nature of the software, organizations relying on NI Circuit Design Suite for product development or testing may face operational delays and financial losses. Additionally, if exploited in a targeted manner, attackers could gain footholds within corporate networks, leading to broader compromise. The local attack vector and user interaction requirement somewhat limit the attack surface; however, phishing or social engineering campaigns targeting engineers and designers could facilitate exploitation. The absence of known exploits in the wild suggests that immediate widespread attacks are unlikely but does not preclude targeted attacks against high-value targets.

European organizations should implement several specific measures beyond generic patching advice: 1) Restrict access to NI Circuit Design Suite installations to trusted users only, minimizing exposure to untrusted files. 2) Educate engineering and design teams about the risks of opening unsolicited or unexpected .sym files, emphasizing cautious handling of files from external sources. 3) Employ endpoint security solutions capable of detecting anomalous behavior associated with memory corruption exploits, such as unusual process activity or code injection attempts. 4) Implement application whitelisting to prevent execution of unauthorized binaries that could be dropped or executed as part of an exploit chain. 5) Use network segmentation to isolate design workstations from broader corporate networks, limiting lateral movement if exploitation occurs. 6) Monitor file shares and email gateways for suspicious .sym files and consider deploying content disarm and reconstruction (CDR) technologies to sanitize incoming files. 7) Maintain up-to-date backups of design data to enable recovery in case of disruption. 8) Engage with NI for timely patch releases and apply updates promptly once available. 9) Consider deploying sandbox environments for opening untrusted design files to contain potential exploitation attempts.
