CVE-2024-3980

9.9 CRITICAL

📋 TL;DR

CVE-2024-3980 is a path traversal vulnerability in MicroSCADA Pro/X SYS600 that allows authenticated users to manipulate file paths, potentially accessing or modifying critical system files. This affects organizations using Hitachi Energy's MicroSCADA Pro/X SYS600 product for industrial control systems. The vulnerability requires authentication but has a critical CVSS score of 9.9 due to potential system compromise.

💻 Affected Systems

Products:
  • MicroSCADA Pro/X SYS600
Versions: All versions prior to 10.3.2
Operating Systems: Windows
Default Config Vulnerable: ⚠️ Yes
Notes: Requires authenticated user access; typically deployed in industrial control system environments.

📦 What is this software?

⚠️ Risk & Real-World Impact

🔴

Worst Case

Complete system compromise allowing attackers to modify critical control system files, disrupt industrial operations, or install persistent malware.

🟠

Likely Case

Unauthorized access to sensitive configuration files, potential data theft, or limited system manipulation by authenticated malicious insiders.

🟢

If Mitigated

Limited impact if proper access controls, network segmentation, and monitoring are in place to detect and block traversal attempts.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

Public PoC: ✅ No
Weaponized: UNKNOWN
Unauthenticated Exploit: ✅ No
Complexity: LOW

Exploitation requires authenticated access but path traversal techniques are well-documented and relatively simple to implement.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: 10.3.2

Vendor Advisory: https://publisher.hitachienergy.com/preview?DocumentID=8DBD000160&LanguageCode=en&DocumentPartId=&Action=Launch

Restart Required: Yes

Instructions:

1. Download patch from Hitachi Energy support portal. 2. Backup current configuration. 3. Apply patch following vendor instructions. 4. Restart system. 5. Verify patch installation.

🔧 Temporary Workarounds

Restrict User Privileges

all

Limit authenticated users to minimum necessary permissions to reduce attack surface.

Network Segmentation

all

Isolate MicroSCADA systems from general network access using firewalls and VLANs.

🧯 If You Can't Patch

  • Implement strict access controls and monitor for unusual file access patterns.
  • Deploy application-level firewalls to detect and block path traversal attempts.

🔍 How to Verify

Check if Vulnerable:

Check system version in MicroSCADA Pro/X SYS600 administration interface. If version is below 10.3.2, system is vulnerable.

Check Version:

Check version in MicroSCADA Pro/X SYS600 administration panel or configuration files.

Verify Fix Applied:

Verify version shows 10.3.2 or higher in administration interface and test file access controls.

📡 Detection & Monitoring

Log Indicators:

  • Unusual file access patterns
  • Failed authentication attempts followed by file operations
  • Access to system directories by non-admin users

Network Indicators:

  • Unusual traffic to system directories
  • Multiple file access attempts from single user session

SIEM Query:

source="microscada" AND (event_type="file_access" AND path CONTAINS ".." OR path CONTAINS "/etc" OR path CONTAINS "/windows")
