CVE-2025-25266
📋 TL;DR
This vulnerability in Tecnomatix Plant Simulation allows unauthorized attackers to delete files even when system access should be prohibited. It affects Tecnomatix Plant Simulation V2302 and V2404 versions before specific patch releases, potentially leading to data loss or unauthorized system file modification.
💻 Affected Systems
- Tecnomatix Plant Simulation V2302
- Tecnomatix Plant Simulation V2404
📦 What is this software?
⚠️ 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.
🎯 Exploit Status
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
windowsApply 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
allIsolate 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.
