CVE-2025-7849
📋 TL;DR
A memory corruption vulnerability in NI LabVIEW allows arbitrary code execution when users open specially crafted VI files. This affects LabVIEW 2025 Q1 and earlier versions. Attackers could gain full control of affected systems through crafted files.
💻 Affected Systems
- NI LabVIEW
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control, data theft, and lateral movement capabilities.
Likely Case
Local privilege escalation or remote code execution within the LabVIEW context, potentially leading to data exfiltration.
If Mitigated
Limited impact with proper file validation and user awareness preventing malicious file execution.
🎯 Exploit Status
Exploitation requires user interaction to open malicious VI files. No public exploit code is currently available.
🛠️ Fix & Mitigation
✅ Official Fix
