CVE-2025-2631

Remediation/Mitigation Strategy: CVE-2025-2631 - NI LabVIEW Out-of-Bounds Write

Description of Vulnerability:

An out-of-bounds write vulnerability exists in the InitCPUInformation() function of NI LabVIEW. This is due to improper bounds checking during processing.

Severity:

Known Exploit:

Successful exploitation requires an attacker to convince a user to open a specially crafted LabVIEW Virtual Instrument (VI) file. Opening the crafted VI triggers the out-of-bounds write.

Impact:

Information Disclosure: The vulnerability can lead to the disclosure of sensitive information residing in memory.
Arbitrary Code Execution: An attacker may be able to leverage the out-of-bounds write to execute arbitrary code on the affected system, potentially leading to complete system compromise.

Affected Versions:

Mitigation Strategy:

Upgrade LabVIEW: Upgrade to a patched version of LabVIEW where the vulnerability has been addressed. Contact National Instruments for information about available patches or later versions.
User Education: Educate LabVIEW users about the risks associated with opening untrusted VI files. Emphasize the importance of only opening VIs from trusted sources.
Source Validation: Implement processes to validate the source and integrity of VI files before opening them. This includes verifying digital signatures where available and communicating with the developer if unsure.
Code Review (Development Environment): If custom VIs are being developed, implement code review processes with a focus on bounds checking, input validation, and memory management within LabVIEW.
Sandboxing (Advanced): In high-risk environments, consider running LabVIEW within a sandboxed environment. This can limit the impact of a successful exploit by restricting the privileges and resources available to the application. However, sandboxing can also impact the functionality of LabVIEW.
Endpoint Detection and Response (EDR): Ensure that systems running LabVIEW have up-to-date EDR solutions. These tools can detect and potentially prevent malicious code execution stemming from exploited VIs. Configure EDR solutions to monitor for unusual LabVIEW behavior.
