Summary

Siemens Tecnomatix Plant Simulation contains multiple file parsing vulnerabilities (CWE-125 out-of-bounds read, CWE-119 improper restriction of operations, CWE-787 out-of-bounds write, CWE-476 null pointer dereference, CWE-121 stack-based buffer overflow) in WRL file format handling. Affected versions: V2302 before 2302.0016 and V2404 before 2404.0005. Opening a malicious WRL file can cause application crash or arbitrary code execution. Siemens has released patched versions.

What this means
What could happen
If an operator opens a malicious WRL file in Tecnomatix Plant Simulation, the application could crash or allow arbitrary code execution on the engineering workstation, potentially compromising plant simulation data and engineering systems.
Who's at risk
Manufacturing engineers and plant simulation specialists who use Siemens Tecnomatix Plant Simulation for factory planning and process modeling. This affects organizations in automotive, food and beverage, semiconductor, and discrete manufacturing sectors that rely on Tecnomatix for digital plant design.
How it could be exploited
An attacker sends a specially crafted WRL (Virtual Reality Markup Language) file to an operator. When the operator opens the file in Tecnomatix Plant Simulation, the application parses the malicious file, triggering a memory corruption vulnerability that causes the application to crash or execute arbitrary code with the user's privileges.
Prerequisites
  • User must open a malicious WRL file in the affected application
  • File must be in WRL format
  • User must have Tecnomatix Plant Simulation V2302 (before 0016) or V2404 (before 0005) installed
