⚠️ Risk & Real-World Impact

🔴

Worst Case

Critical system files could be deleted, causing system instability, production downtime, or permanent data loss affecting manufacturing operations.

🟠

Likely Case

Unauthorized deletion of application files, configuration files, or user data leading to operational disruption.

🟢

If Mitigated

Limited impact with proper access controls, network segmentation, and monitoring in place.

🌐 Internet-Facing: MEDIUM
🏢 Internal Only: HIGH

🎯 Exploit Status

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

Exploitation requires some level of access to the system, but the vulnerability bypasses intended file deletion restrictions.

🛠️ Fix & Mitigation

✅ Official Fix

Patch Version: V2302.0021 for V2302, V2404.0010 for V2404

Vendor Advisory: https://cert-portal.siemens.com/productcert/html/ssa-507653.html

Restart Required: Yes

Instructions:

1. Download the appropriate patch from Siemens support portal. 2. Backup current installation. 3. Run the patch installer. 4. Restart the application and verify version.

🔧 Temporary Workarounds

Restrict File System Permissions

windows

Apply strict file system permissions to limit which users can delete files in Plant Simulation directories.

icacls "C:\Program Files\Siemens\Plant Simulation\*" /deny Users:D
icacls "C:\ProgramData\Siemens\Plant Simulation\*" /deny Users:D

Network Segmentation

all

Isolate Plant Simulation systems from untrusted networks and limit access to authorized users only.

🧯 If You Can't Patch

  • Implement strict access controls and principle of least privilege for all Plant Simulation users.
  • Enable detailed file system auditing and monitor for unauthorized file deletion attempts.

🔍 How to Verify

Check if Vulnerable:

Check Plant Simulation version via Help > About menu. If version is V2302 < 0021 or V2404 < 0010, system is vulnerable.

Check Version:

Not applicable - check via application GUI Help > About menu

Verify Fix Applied:

After patching, verify version shows V2302.0021 or V2404.0010 in Help > About menu.

📡 Detection & Monitoring

Log Indicators:

  • Unexpected file deletion events in Windows Security Event Log (Event ID 4663)
  • Application logs showing unauthorized file operations

Network Indicators:

  • Unusual network connections to Plant Simulation systems from unauthorized sources

SIEM Query:

EventID=4663 AND ObjectName LIKE "%Plant Simulation%" AND AccessMask=0x10000
