Full Report
Siemens Teamcenter Visualization and Tecnomatrix Plant Simulation contains multiple file parsing vulnerabilities that could be triggered when the application reads files in WRL format. If a user is tricked to open a malicious file with any of the affected products, this could lead the application to crash or potentially lead to arbitrary code execution. Siemens has released new versions for the affected products and recommends to update to the latest versions.

- **CVSS Score:**
- CVSS v3.1: 7.8 (High)
- CVSS v4.0: 7.3 (High)
- **CWE:**
- CWE-119 (Improper Restriction of Operations within the Bounds of a Memory Buffer)
- CWE-121 (Stack-based Buffer Overflow)
- CWE-125 (Out-of-bounds Read)
- CWE-416 (Use After Free)
- CWE-787 (Out-of-bounds Write)
## Affected Systems
- **Products:** Teamcenter Visualization and Tecnomatix Plant Simulation
- **Versions:**
- Teamcenter Visualization V14.3: All versions < V14.3.0.13
- Teamcenter Visualization V2312: All versions < V2312.0009
- Teamcenter Visualization V2406: All versions < V2406.0007
- Teamcenter Visualization V2412: All versions < V2412.0002
- Tecnomatix Plant Simulation V2302: All versions < V2302.0017
- Tecnomatix Plant Simulation V2404: All versions < V2404.0008
- **Configurations:** Systems where these applications are used to open or process WRL (VRML) format files.
## Vulnerability Description
The affected applications contain several memory safety flaws within their file parsing engines. Specifically, when processing maliciously crafted **WRL (Web Resource Locale/VRML)** files, the software fails to properly validate memory boundaries or object lifecycles. This includes stack-based overflows, out-of-bounds reads/writes, and use-after-free conditions.
## Exploitation
- **Status:** Not exploited (reported via coordinated disclosure; no known active exploitation).
- **Complexity:** Medium (requires crafting a specific malicious file).
- **Attack Vector:** Local (requires a user to be tricked into opening a malicious file; User Interaction is required).
## Impact
- **Confidentiality:** High (Potential for arbitrary code execution and data theft).
- **Integrity:** High (Potential for system modification via code execution).
- **Availability:** High (Can lead to application crashes or denial of service).
## Remediation
### Patches
Siemens recommends updating to the following versions or later:
- **Teamcenter Visualization V14.3:** Update to V14.3.0.13
- **Teamcenter Visualization V2312:** Update to V2312.0009
- **Teamcenter Visualization V2406:** Update to V2406.0007
- **Teamcenter Visualization V2412:** Update to V2412.0002
- **Tecnomatix Plant Simulation V2302:** Update to V2302.0017
- **Tecnomatix Plant Simulation V2404:** Update to V2404.0008
### Workarounds
- Limit the opening of WRL files to those from trusted and known sources only.
- Apply general "Least Privilege" principles to the user accounts running the affected software.
## Detection
- **Indicators of Compromise:** Application crashes (Access Violations) when opening WRL files.
- **Detection Methods:** Security teams can use file integrity monitoring or sandbox analysis to inspect suspicious WRL files before they are opened in production environments.
