CVE-2025-2829
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 · uneditedA local code execution vulnerability exists in the Rockwell Automation Arena® due to a threat actor being able to write outside of the allocated memory buffer. The flaw is a result of improper validation of user-supplied data. If exploited a threat actor can disclose information and execute arbitrary code on the system. To exploit the vulnerability a legitimate user must open a malicious DOE file.
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 · high confidenceA buffer overflow vulnerability exists in Rockwell Automation Arena® due to improper validation of user-supplied data when parsing DOE files, allowing a threat actor to write outside allocated memory bounds. Successful exploitation enables information disclosure and arbitrary code execution through a malicious DOE file opened by a legitimate user.

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 checksWork through these to decide whether this CVE applies to you.
-
Check installed Arena versionOpen Arena and navigate to Help > About, or check the Windows Programs and Features list, or locate the arena.exe file in the installation directory and view its properties/version infoAffected if The version displayed is earlier than 16.20.09 (e.g., 16.20.00, 16.10.x, etc.)
-
Identify DOE file usageSearch for .doe files in the system using File Explorer: look in common project directories, recent documents, or the Arena working folder for files with .doe extensionAffected if Any .doe files exist on the system, indicating the DOE parsing feature is relevant to this installation
-
Check for DOE import functionalityIn Arena, look for File > Open, File > Import, or similar menu options that reference DOE files, or check recent file history for .doe file openingsAffected if The DOE file import/open feature is available and has been used recently
-
Confirm DOE parsing is enabled by defaultReview Arena's default file associations and settings - DOE parsing appears to be a built-in capability triggered upon opening .doe files rather than a separately enabled moduleAffected if The software can natively open and parse .doe files without additional configuration
You are affected if Arena is installed at any version below 16.20.09 and the system has the ability to open or has opened DOE files.
Generated from the published advisory. Verify against your own configuration.
Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
dbcve · scoped16.20.09
Avoid opening untrusted DOE files from unknown sources; apply official vendor patches when released; consider running Arena with reduced privileges to limit impact of potential code execution.
Arena 16.20.09 or later
- 1. Navigate to the Rockwell Automation support website at www.rockwellautomation.com
- 2. Locate the Arena software download section
- 3. Download Arena version 16.20.09 or later
- 4. Verify the file integrity using provided checksums if available
- 5. Close any running instances of Arena
- 6. Install the updated Arena version following the standard installation procedure
- 7. After installation, verify the installed version matches 16.20.09 or later
- 8. Instruct users to only open DOE files from trusted sources to mitigate social engineering attempts
