CVE-2025-2293 Rockwell Automation CVE debrief

Who should care

Organizations using Rockwell Automation Arena, especially OT/ICS teams, engineering workstation owners, and administrators who handle DOE project files.

Technical summary

The advisory describes an improper validation issue in Rockwell Automation Arena that permits writing outside an allocated memory buffer when a malicious DOE file is opened. The result is a local code execution condition with potential information disclosure. The affected product listing is Rockwell Automation Arena: <=16.20.08, and the listed mitigation is to upgrade to version 16.20.09 or later.

Defensive priority

High — prioritize patching Arena installations that may open external or untrusted DOE files, especially on systems used for engineering or process support.

Recommended defensive actions

• Upgrade Rockwell Automation Arena to V16.20.09 or later.
• Treat DOE files from outside trusted sources as untrusted and review file-handling workflows.
• Apply Rockwell Automation and CISA industrial control system security best practices to reduce exposure.
• Limit user privileges on systems running Arena and restrict unnecessary access to engineering workstations.
• Monitor for unexpected file-open activity or abnormal application behavior around DOE file processing.

Evidence notes

All substantive claims are taken from the supplied CISA CSAF source item ICSA-25-100-07 and its remediation entries. The source describes the issue as a local code execution vulnerability caused by improper validation of user-supplied data, triggered when a legitimate user opens a malicious DOE file, and identifies Rockwell Automation Arena <=16.20.08 as affected with an upgrade to 16.20.09 or later as the primary mitigation.
