Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.

NVD · unedited
A memory abuse issue exists in the Rockwell Automation Arena® Simulation. A custom file can force Arena Simulation to read and write past the end of memory space. Successful use requires user action, such as opening a bad file or webpage. If used, a threat actor could execute code or disclose information.

Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.

dbcve analysis · moderate confidence

A memory corruption vulnerability exists in Rockwell Automation Arena Simulation where specially crafted files can cause the application to read or write beyond allocated memory boundaries. Successful exploitation requires user interaction such as opening a malicious file, and could allow an attacker to achieve code execution or disclose sensitive information.

MitigationApply vendor patches when available; instruct users to avoid opening untrusted .aren files or visiting untrusted URLs; consider application sandboxing or network segmentation to limit exposure.

Verify against the referenced sources before acting — the references below are authoritative for this CVE, this summary is not.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.

dbcve checks

Work through these to decide whether this CVE applies to you.

  1. Confirm Arena Simulation software is installed
    Check for Rockwell Automation Arena in Windows Programs and Features, or search for arena.exe in common installation directories (C:\Program Files\Rockwell Software\Arena or C:\Program Files (x86)\Rockwell Software\Arena)
    Affected if The software is present on the system
  2. Identify installed Arena version
    Right-click arena.exe, select Properties, then view the Details tab for Product Version. Alternatively, check the Windows Registry under HKLM\SOFTWARE\Rockwell Software\Arena or HKLM\SOFTWARE\WOW6432Node\Rockwell Software\Arena for the Version value
    Affected if The version number is lower than 16.20.10 (e.g., 16.20.00, 16.10.00, etc.)
  3. Verify .aren file association exists
    Check if .aren files are associated with Arena by opening File Explorer, navigating to a folder containing .aren files, and confirming the file type shows Arena as the default opener. Also check HKCR\.aren in Windows Registry
    Affected if The .aren file extension is registered to open with Arena Simulation
  4. Confirm application is accessible to standard users
    Verify that non-privileged users can launch Arena and access .aren files. Check file permissions on the Arena installation directory and any user-accessible .aren sample files
    Affected if Standard users can open .aren files directly in Arena without admin intervention

The environment is affected if Rockwell Automation Arena is installed with a version lower than 16.20.10 and users can open .aren files with the application.

Interim mitigation

Apply vendor patches when available; instruct users to avoid opening untrusted .aren files or visiting untrusted URLs; consider application sandboxing or network segmentation to limit exposure.

Recommended fix Moderate confidence

Arena Simulation version 16.20.10 or later

  1. 1. Verify the current installed version of Arena Simulation software via Help > About or the application properties
  2. 2. Download Arena Simulation version 16.20.10 or later from the official Rockwell Automation website or your licensed download portal
  3. 3. Close all running instances of Arena Simulation before proceeding with the upgrade
  4. 4. Run the installer with appropriate administrative privileges
  5. 5. Follow the on-screen installation wizard prompts to complete the upgrade
  6. 6. After installation, verify the new version by checking Help > About to confirm version 16.20.10 or higher is installed
  7. 7. Test critical simulation models to ensure functionality is preserved after the upgrade
Caveat Standard upgrade; review release notes for any changes to simulation behavior or deprecated features
