CVE-2025-2286 Rockwell Automation CVE debrief

Who should care

Organizations running Rockwell Automation Arena version 16.20.08 or earlier, especially admins and operators who receive or open DOE files as part of normal engineering workflows.

Technical summary

The CSAF advisory identifies an uninitialized pointer in Rockwell Automation Arena caused by improper validation of user-supplied data. The affected product scope is Rockwell Automation Arena: <=16.20.08. Successful exploitation requires user interaction: a legitimate user must open a malicious DOE file. The vendor and CISA describe possible impacts as information disclosure and arbitrary code execution, and the supplied CVSS vector is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H (7.8 High).

Defensive priority

High for any environment still running affected Arena versions, because the issue can lead to code execution once a user opens a malicious file. Prioritize upgrades and file-handling controls on systems that routinely process DOE files.

Recommended defensive actions

• Upgrade Rockwell Automation Arena to V16.20.09 or later.
• Review and apply the vendor guidance in Rockwell Automation security advisory SD1726.
• Limit opening of unsolicited or untrusted DOE files, especially from external sources.
• Apply industrial control system security best practices referenced by the vendor and CISA.
• Verify asset inventory to confirm whether any systems still run Arena 16.20.08 or earlier.

Evidence notes

This debrief is based on the CISA CSAF advisory ICSA-25-100-07 for CVE-2025-2286, published 2025-04-10 and revised 2025-05-06 with typos fixed. The advisory names Rockwell Automation Arena as the affected product, lists the affected range as <=16.20.08, and states that exploitation requires a legitimate user to open a malicious DOE file. The supplied enrichment indicates the issue is not in CISA KEV.
