CVE-2024-23795
📋 TL;DR
This vulnerability allows remote code execution through a specially crafted WRL file in Tecnomatix Plant Simulation. Attackers can execute arbitrary code in the context of the current process by exploiting an out-of-bounds write buffer overflow. Users of Tecnomatix Plant Simulation V2201 and V2302 before specific patch versions are affected.
💻 Affected Systems
- Tecnomatix Plant Simulation V2201
- Tecnomatix Plant Simulation V2302
📦 What is this software?
⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise with attacker gaining full control over 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 leading to unauthorized access to sensitive engineering data and disruption of manufacturing operations.
If Mitigated
Limited impact with proper network segmentation and file validation controls preventing malicious WRL files from reaching vulnerable systems.
🎯 Exploit Status
Exploitation requires user interaction to open a malicious WRL file, but no authentication is needed once the file is processed.
🛠️ 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 patch from Siemens support portal. 2. Close all Plant Simulation instances. 3. Run the patch installer. 4. Restart the system. 5. Verify the version is updated.
🔧 Temporary Workarounds
Restrict WRL file processing
windowsBlock or restrict processing of WRL files through application controls or file type restrictions.
User awareness training
allTrain users not to open WRL files from untrusted sources.
🧯 If You Can't Patch
- Implement application whitelisting to prevent unauthorized execution of Plant Simulation.
- Use network segmentation to isolate Plant Simulation systems from critical infrastructure.
🔍 How to Verify
Check if Vulnerable:
Check Plant Simulation version in Help > About menu. If version is V2201 < 0012 or V2302 < 0006, system is vulnerable.Check Version:
Not applicable - check via Plant Simulation GUI Help > About menuVerify Fix Applied:
After patching, verify version shows V2201.0012 or V2302.0006 in Help > About menu.📡 Detection & Monitoring
Log Indicators:
- Application crashes when processing WRL files
- Unusual process creation from Plant Simulation
Network Indicators:
- Unusual outbound connections from Plant Simulation systems
SIEM Query:
