Full Report
Siemens Teamcenter Visualization contains a out-of-bound read vulnerability 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.
Analysis Summary
# Vulnerability: Out-of-Bounds Read in Siemens Teamcenter Visualization
## CVE Details
- **CVE ID:** CVE-2025-32454
- **CVSS Score:** 7.8 (High) - CVSS v3.1 / 7.3 (High) - CVSS v4.0
- **CWE:** CWE-125 (Out-of-bounds Read)
## Affected Systems
- **Products:** Siemens Teamcenter Visualization
- **Versions:**
- V14.3: All versions < V14.3.0.14
- V2312: All versions < V2312.0010
- V2406: All versions < V2406.0008
- V2412: All versions < V2412.0004
- **Configurations:** Systems utilized to parse or view WRL (VRML) format files.
## Vulnerability Description
The vulnerability exists within the parsing logic of WRL files. Affected applications lack proper bounds checking when reading data into an allocated structure. By providing a specially crafted WRL file, an attacker can trigger a read past the end of the allocated buffer. This memory corruption can lead to a denial-of-service (application crash) or, more critically, allow for arbitrary code execution in the context of the current process.
## Exploitation
- **Status:** Not exploited (No known reports of active exploitation in the wild or public PoC at this time).
- **Complexity:** Low (CVSS v3.1) / High (CVSS v4.0 reflects the necessity of crafting specific memory layouts for code execution).
- **Attack Vector:** Local (Requires user interaction to open a malicious file).
## Impact
- **Confidentiality:** High (Potential for memory disclosure or code execution).
- **Integrity:** High (Potential for arbitrary code execution).
- **Availability:** High (Application crash or system compromise).
## Remediation
### Patches
Siemens recommends updating affected products to the following versions or later:
- **V14.3:** Update to V14.3.0.14
- **V2312:** Update to V2312.0010
- **V2406:** Update to V2406.0008
- **V2412:** Update to V2412.0004
### Workarounds
- **Restrict File Sources:** Do not open WRL files obtained from untrusted or unknown sources.
- **Access Control:** Protect network access and follow industrial security operational guidelines to ensure only authorized users can interact with the software.
## Detection
- **Indicators of Compromise:** Unexpected application crashes when opening WRL files; unusual child processes spawned by Teamcenter Visualization.
- **Detection Methods:** Use file integrity monitoring and endpoint detection and response (EDR) tools to monitor for suspicious activity following the ingestion of 3D model files.
