CVE-2024-11155
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 “use after free” code execution vulnerability exists in the Rockwell Automation Arena® that could allow a threat actor to craft a DOE file and force the software to use a resource that was already used. 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 use-after-free vulnerability in Rockwell Automation Arena allows arbitrary code execution via a specially crafted DOE file. The vulnerability occurs when the software attempts to use a resource that has already been freed, potentially enabling an attacker to control memory and execute arbitrary code.

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.
-
Identify if Rockwell Automation Arena is installedCheck the Windows Program Files directory for the Arena folder, or look in Add/Remove Programs for Rockwell Automation ArenaAffected if Arena software is present on the system
-
Determine the installed Arena versionOpen Arena and navigate to Help > About, or check the executable properties of arena.exe in the installation directoryAffected if The reported version is lower than 16.20.06 (e.g., 16.20.00, 16.10.x, etc.)
-
Verify DOE file functionality is accessibleAttempt to open a DOE file through File > Open in Arena, or check if .doe file association exists in the systemAffected if DOE file import/open feature is available and functional
-
Inspect recent DOE file access logs or temporary filesCheck the Arena working directory or recent documents for .doe file activityAffected if The system has recently opened or processed DOE files from any source
The environment is affected if Rockwell Automation Arena is installed with a version lower than 16.20.06 and the DOE file import feature is accessible.

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 · scoped16.20.06
Users should avoid opening untrusted DOE files from unverified sources. Organizations should implement file validation policies and consider applying any vendor security patches when available.
Arena 16.20.06
- Obtain Arena version 16.20.06 or later from the official Rockwell Automation website or their support portal
- Create a backup of all important Arena files, projects, and DOE files before proceeding
- Uninstall the current version of Arena from the system
- Install Arena version 16.20.06 or later using the standard installation process
- Verify the installation completed successfully by checking the software version
- Test that existing projects and DOE files function correctly with the updated version
