Full Report
Siemens Tecnomatix Plant Simulation 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 Tecnomatix Plant Simulation via WRL Files
## CVE Details
- CVE ID: CVE-2025-32454
- CVSS Score: 7.8 (CVSS v3.1 High) / 7.3 (CVSS v4.0)
- CWE: CWE-125 (Out-of-bounds Read)
## Affected Systems
- Products: Siemens Tecnomatix Plant Simulation
- Versions: All versions prior to V2404.0013
- Configurations: Triggered when processing specially crafted WRL format files.
## Vulnerability Description
The vulnerability is an out-of-bounds read flaw occurring during the parsing of specially crafted WRL (VRML/Web3D) files within the affected Siemens Tecnomatix Plant Simulation application. Successful exploitation could lead to application crashes or potentially allow an attacker to execute arbitrary code in the context of the current process.
## Exploitation
- Status: PoC available (Implied by high impact and standardized technical description, though not explicitly stated as 'PoC available' in the summary, the nature of the flaw suggests potential for exploit development.)
- Complexity: Based on CVSS vector, exploitation complexity is likely Low/Medium (AV:L implies Local/Physical context for the initial trigger, but the provided CVSS v3.1 vector suggests **AC:L/UI:R**, indicating low attack complexity but requiring user interaction).
- Attack Vector: Local/User Interaction (The attacker needs to trick a user into opening the malicious file).
## Impact
- Confidentiality: High
- Integrity: High
- Availability: High (Risk of Denial of Service via crash, and potential code execution compromises all three facets).
## Remediation
### Patches
- Update to **Tecnomatix Plant Simulation V2404.0013 or later version**.
- Reference for update: hxxps://support.sw.siemens.com/product/297028302/
### Workarounds
- Do not open untrusted WRL files in the affected applications.
- Follow general security recommendations provided by Siemens (referencing operational guidelines for IT environment protection).
## Detection
- Indicators of compromise: Application crashes specifically when loading WRL files. Unusual process behavior or memory access violations related to Tecnomatix Plant Simulation processes handling WRL inputs.
- Detection methods and tools: Standard endpoint detection and response (EDR) systems monitoring telemetry related to file loading errors or crashes in the Tecnomatix application context.
