ComplexityLow
User InteractionNone needed
Summary
Siemens Tecnomatix Plant Simulation versions V2302 (before 2302.0021) and V2404 (before 2404.0010) do not properly restrict simulation model access to the filesystem. An attacker with local access could exploit improper filesystem access controls to read, modify, or delete arbitrary files on the affected device, including critical simulation data and system files.
What this means
What could happen
An attacker with local access to a device running Tecnomatix Plant Simulation could read, modify, or delete arbitrary files on the system, potentially compromising simulation data, configuration files, or causing the simulation environment to become unusable.
Who's at risk
This vulnerability affects organizations using Siemens Tecnomatix Plant Simulation for manufacturing process modeling and simulation. It is relevant to automotive, machinery, and discrete manufacturing facilities that rely on simulation workstations for production planning and process optimization.
How it could be exploited
An attacker must first gain local access to the device running Tecnomatix Plant Simulation. Once local, they can craft a malicious simulation model that exploits improper filesystem access controls to read or delete arbitrary files outside the intended simulation directory, bypassing the application's intended filesystem restrictions.
Prerequisites
- Local access to the device running Tecnomatix Plant Simulation
- Ability to create or modify simulation model files
- No authentication credentials required for exploitation once local access is achieved
