CVE-2023-44086
📋 TL;DR
This vulnerability allows remote code execution through specially crafted SPP files in Tecnomatix Plant Simulation software. Attackers can exploit an out-of-bounds read vulnerability to execute arbitrary code in the context of the current process. Users of Tecnomatix Plant Simulation V2201 (before V2201.0009) and V2302 (before V2302.0003) are affected.
💻 Affected Systems
- Tecnomatix Plant Simulation V2201
- Tecnomatix Plant Simulation V2302

⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control of the affected system, potentially leading to data theft, ransomware deployment, or lateral movement within the network.
Likely Case
Local privilege escalation or remote code execution when users open malicious SPP files, potentially leading to data exfiltration or malware installation.
If Mitigated
Limited impact if proper file validation and user awareness prevent malicious SPP files from being processed.
🎯 Exploit Status
Exploitation requires user interaction to open malicious SPP files. No public exploit code has been identified.
🛠️ 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 latest patch from Siemens support portal. 2. Close all Plant Simulation instances. 3. Run the installer with administrative privileges. 4. Restart the system.
🔧 Temporary Workarounds
Restrict SPP file processing
windowsBlock or restrict processing of SPP files through application controls or file policies.
User awareness training
allTrain users not to open SPP files from untrusted sources.
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of unauthorized code
- Use network segmentation to isolate Plant Simulation systems from critical assets
🔍 How to Verify
Check if Vulnerable:
Check Plant Simulation version in Help > About menu. If version is V2201 < 0009 or V2302 < 0003, system is vulnerable.Check Version:
Not applicable - check via application GUI Help > AboutVerify Fix Applied:
After patching, verify version shows V2201.0009 or V2302.0003 in Help > About menu.📡 Detection & Monitoring
Log Indicators:
- Unusual process creation from Plant Simulation executable
- Multiple failed SPP file parsing attempts
Network Indicators:
- Outbound connections from Plant Simulation to unknown IPs
- Unusual file transfers from Plant Simulation systems
SIEM Query:
Process creation where parent_process contains 'plantsim' AND (process contains 'cmd.exe' OR process contains 'powershell.exe')
