CVE-2023-45204
📋 TL;DR
A type confusion vulnerability in Tecnomatix Plant Simulation allows attackers to execute arbitrary code by tricking users into opening malicious IGS files. This affects all versions of Plant Simulation V2201 before V2201.0009 and V2302 before V2302.0003. Users who process untrusted IGS files are at risk.
💻 Affected Systems
- Tecnomatix Plant Simulation V2201
- Tecnomatix Plant Simulation V2302

⚠️ Risk & Real-World Impact
Worst Case
Full system compromise with attacker gaining the same privileges as the Plant Simulation process, potentially leading to data theft, ransomware deployment, or lateral movement.
Likely Case
Local code execution when a user opens a malicious IGS file, allowing attackers to install malware, steal credentials, or access sensitive plant simulation data.
If Mitigated
Limited impact if users only open trusted IGS files from verified sources and the application runs with minimal privileges.
🎯 Exploit Status
Exploitation requires user interaction to open malicious IGS file. No public exploit code available as of analysis.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: V2201.0009 for V2201, V2302.0003 for V2302
Vendor Advisory: https://cert-portal.siemens.com/productcert/pdf/ssa-524778.pdf
Restart Required: Yes
Instructions:
1. Download the update from Siemens support portal. 2. Close all Plant Simulation instances. 3. Run the installer with administrative privileges. 4. Restart system if prompted.
🔧 Temporary Workarounds
Restrict IGS file handling
allBlock or restrict processing of IGS files from untrusted sources
Run with reduced privileges
windowsRun Plant Simulation with limited user account privileges to reduce impact
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of unauthorized code
- Educate users to never open IGS files from untrusted sources and use file integrity monitoring
