CVE-2023-37375
📋 TL;DR
A stack-based buffer overflow vulnerability in Tecnomatix Plant Simulation allows attackers to execute arbitrary code by tricking users into opening malicious SPP files. This affects all versions of Plant Simulation V2201 before V2201.0008 and V2302 before V2302.0002. Users who open untrusted SPP files are at risk.
💻 Affected Systems
- Tecnomatix Plant Simulation V2201
- Tecnomatix Plant Simulation V2302

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining the same privileges as the Plant Simulation process, potentially leading to lateral movement, data theft, or ransomware deployment.
Likely Case
Local privilege escalation or remote code execution when users open malicious SPP files, potentially leading to malware installation or data exfiltration.
If Mitigated
Limited impact with proper user training and file validation, potentially causing application crashes but no code execution.
🎯 Exploit Status
Exploitation requires user interaction to open malicious SPP file. No authentication bypass needed but requires social engineering.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: V2201.0008 for V2201, V2302.0002 for V2302
Vendor Advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-764801.pdf
Restart Required: Yes
Instructions:
1. Download the update from Siemens support portal. 2. Install the update following Siemens installation guide. 3. Restart the system. 4. Verify version is updated.
🔧 Temporary Workarounds
Restrict SPP file handling
windowsConfigure Windows to open SPP files with a different application or block them entirely
Use Windows Group Policy to modify file associations for .spp files
User awareness training
allTrain users to only open SPP files from trusted sources
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of unauthorized code
- Use endpoint detection and response (EDR) to monitor for suspicious process creation
