Attack VectorLocal
Auth RequiredLow
ComplexityLow
User InteractionRequired
Summary

Arena Input Analyzer versions 16.20.03 and earlier contain a vulnerability that allows local code execution and information disclosure. Successful exploitation requires local access to the workstation and user interaction. The vulnerability is classified as CWE-1284 (Improper Validation of Specified Type of Input).

What this means
What could happen
An attacker with local access could run arbitrary code on a workstation running Arena Input Analyzer, potentially compromising confidentiality and integrity of engineering data or process configurations. This is a local threat and does not directly impact running operations, but could enable manipulation of simulation or analysis results used for process decisions.
Who's at risk
Engineering and simulation teams using Rockwell Automation Arena Input Analyzer should care about this issue. This affects workstations used for process simulation, analysis, and optimization before deployment to production systems. The risk is greatest if simulation or analysis data is used to set real-world process parameters on PLCs or other control devices.
How it could be exploited
An attacker must first gain local access to a workstation running Arena Input Analyzer. The vulnerability requires user interaction (opening a file or performing an action in the GUI). Once triggered, the attacker can execute arbitrary code with the privileges of the logged-in user.
Prerequisites
  • Local access to the workstation running Arena Input Analyzer
  • User must trigger the vulnerability through GUI interaction (e.g., opening a malicious file)
  • Arena Input Analyzer version 16.20.03 or earlier must be installed
