Summary

Arena Input Analyzer versions 16.20.03 and earlier contain a local code execution and information disclosure vulnerability that allows an attacker with user-level access to run arbitrary code and access sensitive data. The vulnerability is triggered through user interaction with malicious input or files. Rockwell Automation has released version 16.20.04 with a fix.

What this means
What could happen
An attacker with local access to a machine running Arena Input Analyzer could execute arbitrary code and steal sensitive information from the application, potentially compromising engineering data or process configurations.
Who's at risk
Rockwell Automation Arena Input Analyzer users should prioritize this update. The tool is used by manufacturing, water, and utilities engineers for simulation and process design. Unpatched versions pose a risk if accessed by compromised user accounts or during remote engineering work.
How it could be exploited
An attacker with user-level access to a Windows machine running Arena Input Analyzer could exploit a local code execution vulnerability triggered through a malicious file or input, allowing them to run arbitrary commands in the context of the application or user account.
Prerequisites
  • Local access to the machine running Arena Input Analyzer
  • User-level credentials on the affected machine
  • User interaction required (e.g., opening a malicious file or accepting a prompt)
