AI-suggested
- Apply patches or updates from NI as soon as they become available to address CVE-2025-64461.
- Until patches are released, restrict the opening of VI files from untrusted or unknown sources to minimize exposure.
- Implement strict file validation and scanning mechanisms on email gateways and file-sharing platforms to detect and block malicious VI files.
- Educate users about the risks of opening unsolicited or suspicious VI files and encourage verification of file origins.
- Employ application whitelisting to limit execution of unauthorized LabVIEW components or scripts.
- Use network segmentation to isolate systems running LabVIEW from less secure network zones, reducing the risk of lateral movement.
- Monitor system and application logs for unusual behavior indicative of exploitation attempts.
- Consider deploying endpoint detection and response (EDR) solutions capable of identifying memory corruption exploits.
- Maintain regular backups of critical LabVIEW projects and configurations to enable recovery in case of compromise.
- Coordinate with NI support and subscribe to security advisories for timely updates on patches and exploit developments.
Description
There is an out of bounds write vulnerability in NI LabVIEW in mgocre_SH_25_3!RevBL() when parsing a corrupted VI file. 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 VI. This vulnerability affects NI LabVIEW 2025 Q3 (25.3) and prior versions.
