Summary
Tecnomatix Plant Simulation V2302 (before 2302.0018) and V2404 (before 2404.0007) contain multiple file parsing vulnerabilities in WRL file handling. These vulnerabilities include buffer overflow (CWE-787), out-of-bounds read (CWE-125), use-after-free (CWE-416), and stack-based buffer overflow (CWE-121). When a user opens a malicious WRL file, the application may crash or execute arbitrary code with user privileges.
What this means
What could happen
If an operator or engineer opens a malicious WRL file in Tecnomatix Plant Simulation, the application could crash, losing unsaved work and disrupting simulation activities, or an attacker could execute arbitrary code with the user's privileges on the engineering workstation.
Who's at risk
Manufacturing and process engineering teams who use Siemens Tecnomatix Plant Simulation for digital factory planning, layout simulation, and process optimization. This includes automotive, discrete manufacturing, and consumer goods industries where plant simulation is used on engineering workstations.
How it could be exploited
An attacker creates a malicious WRL (VRML) file and tricks an engineer or operator into opening it using Tecnomatix Plant Simulation. When the file is parsed, one of the parsing vulnerabilities (buffer overflow, out-of-bounds read, or use-after-free) is triggered, causing the application to crash or allowing code execution on the engineering workstation.
Prerequisites
- User must open a malicious WRL file in Tecnomatix Plant Simulation
- User interaction required (the file must be explicitly opened by the user)
