CVE-2026-0714
📋 TL;DR
This CVE describes a physical attack vulnerability in Moxa industrial computers where an attacker with invasive physical access can capture TPM communications via the SPI bus to potentially decrypt eMMC contents. It affects systems using TPM-backed LUKS full-disk encryption on Moxa Industrial Linux 3. The attack requires extended physical access, specialized equipment, and cannot be performed remotely.
💻 Affected Systems
- Moxa industrial computers with TPM-backed LUKS full-disk encryption
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete compromise of encrypted data on the device, allowing attackers to access sensitive industrial control system configurations, credentials, and proprietary data stored on the eMMC.
Likely Case
Limited impact due to the high barrier of physical access requirements; most likely to affect devices in unsecured physical locations or during maintenance/transport.
If Mitigated
Minimal impact if devices are physically secured in controlled environments with access restrictions and monitoring.
🎯 Exploit Status
Exploitation requires invasive physical access, specialized SPI bus monitoring equipment, and significant time for signal capture/analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: N/A
Restart Required: No
Instructions:
Check vendor advisory for updates; currently no software patch available. Focus on physical security controls.
🔧 Temporary Workarounds
Physical Security Enhancement
allImplement strict physical access controls to prevent unauthorized access to devices.
Tamper Detection Implementation
allUse tamper-evident seals and physical intrusion detection mechanisms.
🧯 If You Can't Patch
- Deploy devices in physically secure locations with access controls and surveillance
- Implement tamper-evident seals and regular physical inspection procedures
🔍 How to Verify
Check if Vulnerable:
Check if device uses Moxa Industrial Linux 3 with TPM-backed LUKS encryption via SPI bus connection.
Check Version:
Check system documentation or contact Moxa support for specific device configuration details.
Verify Fix Applied:
No software fix available; verify physical security controls are implemented.
