CVE-2024-11157
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 third-party vulnerability exists in the Rockwell Automation Arena® that could allow a threat actor to write beyond the boundaries of allocated memory in a DOE file. If exploited, a threat actor could leverage this vulnerability to execute arbitrary code. To exploit this vulnerability, a legitimate user must execute the malicious code crafted by the threat actor.
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 confidenceA buffer overflow vulnerability exists in Rockwell Automation Arena's DOE file parsing functionality that allows writing beyond allocated memory boundaries, potentially enabling arbitrary code execution. The attack requires a legitimate user to execute a maliciously crafted DOE file.

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.
-
Verify Rockwell Automation Arena is installedCheck Program Files for Rockwell Automation Arena directory, or look for Arena in the Windows Start Menu/Installed Programs listAffected if Arena software is present on the system
-
Determine installed Arena versionOpen Arena, go to Help > About, or check the version in Add/Remove Programs, or look for version info in the installation directoryAffected if Version is shown as anything below 16.20.07 (e.g., 16.20.00, 16.10.x, etc.)
-
Identify DOE file handling capabilityCheck if the DOE (Design of Experiments) module is accessible in Arena - look for DOE-related menus, toolbars, or file templates with .doe extension in recent filesAffected if DOE functionality is present and accessible to users
-
Audit user access to DOE filesReview file system permissions on DOE file storage locations and check for recent .doe files in user-accessible directoriesAffected if Users have write access to locations where DOE files are stored or opened
System is affected if Rockwell Automation Arena is installed with a version number lower than 16.20.07 and users have access to the DOE file parsing functionality.

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 · scoped16.20.07
Apply vendor patches when available; until then, enforce least privilege, isolate affected systems, and strictly control DOE file sources as the attack requires user execution of malicious files.
Arena version 16.20.07 or later
- Identify the current installed version of Arena on the system
- Backup all important Arena files, configurations, and DOE files before proceeding
- Obtain Arena version 16.20.07 or later from the official Rockwell Automation download portal or through your Rockwell account
- Uninstall the current vulnerable version of Arena from the system
- Install the new version 16.20.07 or later
- Verify the installation was successful and the version is correct
- Test that DOE files can be opened and manipulated normally in the updated version
