Summary
Teknomatix Plant Simulation V2302 and V2404 contain multiple file parsing vulnerabilities in WRL (Virtual Reality Modeling Language) file handling. These vulnerabilities are triggered when a user opens a malicious WRL file, potentially allowing arbitrary code execution or application crash. The vulnerabilities result from improper bounds checking and memory validation (CWE-125, CWE-119, CWE-787, CWE-476, CWE-121). Siemens has released patched versions: V2302.0016 and V2404.0005.
What this means
What could happen
An attacker could trick a user into opening a malicious WRL file, causing the Tecnomatix Plant Simulation application to crash or potentially execute arbitrary code on the engineering workstation. This could disrupt plant design and simulation workflows or compromise the integrity of plant models used for operational planning.
Who's at risk
Manufacturing and process engineering teams using Siemens Tecnomatix Plant Simulation for plant design, layout, and digital twin modeling. This affects engineering workstations where the simulation software is installed, particularly those that receive design files or WRL imports from external partners or suppliers.
How it could be exploited
An attacker crafts a malicious WRL (Virtual Reality Modeling Language) file and tricks a user into opening it within Tecnomatix Plant Simulation. The application parses the file without proper validation, triggering a buffer overflow or out-of-bounds memory access, leading to application crash or code execution on the workstation running the simulation software.
Prerequisites
- User must open a malicious WRL file in Tecnomatix Plant Simulation
- Affected version of Tecnomatix Plant Simulation must be installed on the target workstation
