CVE-2025-64466
📋 TL;DR
An out-of-bounds read vulnerability in NI LabVIEW's lvre!ExecPostedProcRecPost() function when parsing corrupted VI files could lead to information disclosure or arbitrary code execution. Attackers must trick users into opening specially crafted VI files. This affects NI LabVIEW 2025 Q3 (25.3) and earlier versions.
💻 Affected Systems
- NI LabVIEW
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Arbitrary code execution with the privileges of the LabVIEW user, potentially leading to full system compromise.
Likely Case
Information disclosure through memory leaks or application crashes when users open malicious VI files.
If Mitigated
Limited impact if users only open trusted VI files from verified sources.
🎯 Exploit Status
Exploitation requires user interaction to open malicious VI file. No public exploit code available at this time.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: NI LabVIEW 2025 Q4 (25.4) or later
Restart Required: Yes
Instructions:
1. Download and install NI LabVIEW 2025 Q4 (25.4) or later from NI website. 2. Restart the system after installation. 3. Verify the update was successful by checking the LabVIEW version.
🔧 Temporary Workarounds
Restrict VI file execution
allConfigure application control policies to restrict execution of VI files from untrusted sources.
User awareness training
allTrain users to only open VI files from trusted sources and verify file integrity.
🧯 If You Can't Patch
- Implement strict file validation policies to block VI files from untrusted sources
- Use application sandboxing or virtualization to isolate LabVIEW execution
🔍 How to Verify
Check if Vulnerable:
Check LabVIEW version via Help > About LabVIEW. If version is 25.3 or earlier, system is vulnerable.Check Version:
On Windows: Check Help > About LabVIEW in the application. Command line: Not available.Verify Fix Applied:
Verify LabVIEW version is 25.4 or later via Help > About LabVIEW after patch installation.📡 Detection & Monitoring
Log Indicators:
