CVE-2024-23797
📋 TL;DR
A stack overflow vulnerability in Tecnomatix Plant Simulation allows attackers to execute arbitrary code by tricking users into opening malicious WRL files. This affects all versions of Plant Simulation V2201 before V2201.0012 and V2302 before V2302.0006. Users who open untrusted WRL files are at risk.
💻 Affected Systems
- Tecnomatix Plant Simulation V2201
- Tecnomatix Plant Simulation V2302
📦 What is this software?
⚠️ 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, system manipulation, or lateral movement.
Likely Case
Local code execution when a user opens a malicious WRL file, allowing attackers to install malware, steal credentials, or pivot to other systems.
If Mitigated
Limited impact if proper application whitelisting and user training prevent execution of untrusted files.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious file. No public exploit code has been disclosed as of the advisory date.
🛠️ Fix & Mitigation
✅ Official Fix
Patch Version: V2201.0012 for V2201, V2302.0006 for V2302
Vendor Advisory: https://cert-portal.siemens.com/productcert/html/ssa-017796.html
Restart Required: Yes
Instructions:
1. Download the appropriate update from Siemens support portal. 2. Close all Plant Simulation instances. 3. Run the installer with administrative privileges. 4. Restart the system to ensure changes take effect.
🔧 Temporary Workarounds
Block WRL file execution
windowsPrevent Plant Simulation from opening WRL files by modifying file associations or using application control policies.
Use Group Policy to remove .wrl file association with Plant Simulation
User awareness training
allTrain users to never open WRL files from untrusted sources.
🧯 If You Can't Patch
- Implement application whitelisting to prevent execution of unauthorized files
- Restrict user permissions to limit potential damage from successful exploitation
🔍 How to Verify
Check if Vulnerable:
Check Plant Simulation version in Help > About. If version is V2201 < 0012 or V2302 < 0006, system is vulnerable.Check Version:
Open Plant Simulation and navigate to Help > About menuVerify Fix Applied:
After patching, verify version shows V2201.0012 or V2302.0006 in Help > About.📡 Detection & Monitoring
Log Indicators:
- Unexpected process crashes of Plant Simulation
- Creation of suspicious files or processes after opening WRL files
Network Indicators:
- Unusual outbound connections from Plant Simulation process
SIEM Query:
Process creation where parent process contains 'plantsim' and child process is suspicious (e.g., cmd.exe, powershell.exe)
