CVE-2025-2285 Rockwell Automation CVE debrief

CVE-2025-2285 is a high-severity local code execution issue in Rockwell Automation Arena. According to CISA’s advisory, the flaw stems from improper validation of user-supplied data and an uninitialized pointer. If a legitimate user opens a malicious DOE file, an attacker may be able to disclose information and execute arbitrary code on the system. Rockwell Automation recommends upgrading to Arena V16.20.09 or later.

Vendor: Rockwell Automation
Product: Arena

Who should care

Organizations using Rockwell Automation Arena, especially environments where users may open externally supplied DOE files. Industrial automation and control-system teams should treat this as a priority because successful exploitation requires user interaction but can lead to code execution on an affected workstation or engineering system.

Technical summary

CISA’s CSAF advisory identifies Rockwell Automation Arena <=16.20.08 as affected. The issue is described as a local code execution vulnerability caused by an uninitialized pointer and improper validation of user-supplied data. The published CVSS vector is CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H, with a score of 7.8 (High). Exploitation requires a legitimate user to open a malicious DOE file, which makes this a user-interaction-dependent attack path rather than a remotely triggerable one.

Defensive priority

High for affected Arena deployments. The combination of code execution potential, information disclosure, and the likelihood of user-driven exposure makes patching and file-handling controls important even though the attacker must first get a user to open a malicious file.

Recommended defensive actions

Upgrade Rockwell Automation Arena to V16.20.09 or later.
Restrict and inspect DOE files received from outside trusted sources before opening them.
Apply industrial control system security best practices from Rockwell Automation and CISA to reduce exposure.
Limit which users can open engineering or simulation files on systems used for Arena.
Track CISA advisory ICSA-25-100-07 and Rockwell Automation advisory SD1726 for any further guidance.

Evidence notes

All core claims are drawn from the supplied CISA CSAF record for ICSA-25-100-07 and its referenced Rockwell Automation mitigation guidance.
