AI-suggested
To mitigate this vulnerability, organizations should implement the following specific measures: 1) Restrict the sources of VI files to trusted and verified origins, avoiding opening VI files from untrusted or unknown sources. 2) Employ application whitelisting and endpoint protection solutions capable of detecting anomalous behavior or exploitation attempts related to LabVIEW processes. 3) Educate users on the risks of opening unsolicited or suspicious VI files, emphasizing cautious handling of files received via email or external media. 4) Monitor system and network logs for unusual activity related to LabVIEW or file parsing errors that could indicate exploitation attempts. 5) Isolate LabVIEW workstations in segmented network zones to limit lateral movement if compromise occurs. 6) Maintain regular backups of critical VI files and system configurations to enable recovery from potential compromise. 7) Stay alert for official patches or updates from NI and apply them promptly once available. 8) Consider deploying sandbox environments to open and analyze VI files safely before use in production. These targeted actions go beyond generic advice by focusing on the unique context of LabVIEW and VI file handling.
Description
There is an out of bounds read vulnerability in NI LabVIEW in lvre!DataSizeTDR() 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.
