CVE-2024-4079 is a high-severity vulnerability identified in National Instruments' LabVIEW software, specifically affecting versions up to and including LabVIEW 2024 Q1. The root cause is an out-of-bounds read (CWE-125) due to a missing bounds check within the software. This flaw allows an attacker to read memory outside the intended buffer boundaries, which can lead to information disclosure or potentially arbitrary code execution. Exploitation requires the attacker to convince a legitimate user to open a specially crafted Virtual Instrument (VI) file. Since the vulnerability involves an out-of-bounds read, it can leak sensitive memory contents, potentially exposing confidential data. Furthermore, under certain conditions, it may be leveraged to execute arbitrary code, compromising system integrity and availability. The CVSS v3.1 base score is 7.8, reflecting high severity, with the vector indicating local attack vector (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 publicly linked yet. The vulnerability is particularly concerning because LabVIEW is widely used in industrial automation, research, and engineering environments where system reliability and data confidentiality are critical.

For European organizations, the impact of CVE-2024-4079 can be significant, especially in sectors relying heavily on LabVIEW for automation, testing, and control systems such as manufacturing, automotive, aerospace, and research institutions. Successful exploitation could lead to unauthorized disclosure of sensitive intellectual property or operational data, disruption of automated processes, and potential takeover of affected systems. This could result in operational downtime, financial losses, and damage to reputation. Given LabVIEW's role in critical infrastructure and industrial control systems, the vulnerability could also pose safety risks if exploited to alter system behavior. The requirement for user interaction (opening a malicious VI) means social engineering or phishing campaigns could be used to deliver the exploit, increasing the risk in environments with less stringent user awareness or controls. The absence of known exploits in the wild currently reduces immediate risk but does not eliminate it, especially as threat actors may develop exploits rapidly once details are public.

To mitigate the risk posed by CVE-2024-4079, European organizations should implement the following specific measures: 1) Immediately monitor National Instruments' official channels for patches or updates addressing this vulnerability and prioritize deployment once available. 2) Restrict the use of LabVIEW to trusted users and environments, and implement strict controls on the sources of VI files, including disabling or limiting the ability to open VI files from untrusted or external sources. 3) Enhance user training focused on recognizing and avoiding suspicious or unsolicited VI files, emphasizing the risk of social engineering attacks. 4) Employ application whitelisting and sandboxing techniques to limit the execution scope of LabVIEW and its components, reducing the impact of potential exploitation. 5) Use endpoint detection and response (EDR) tools to monitor for anomalous LabVIEW behavior indicative of exploitation attempts. 6) Conduct regular security audits of systems running LabVIEW, including verifying that only necessary versions are in use and that legacy or unsupported versions are phased out. 7) For critical industrial environments, consider network segmentation to isolate LabVIEW systems from broader enterprise networks, limiting lateral movement in case of compromise.
