Code execution via crafted-file heap overflow
Published Aug 5, 2025 · Updated Feb 26, 2026
Heap-based buffer overflow in Rockwell Automation Arena Simulation 16.20.09 and earlier allows attackers to execute code via a crafted file. The file-processing path reads and writes beyond allocated heap memory when it handles custom content, but Rockwell has not named the parser or file format. Exploitation requires a user to open the malicious file or webpage, enabling code execution or disclosure of process-accessible information.

Exploitability
Present is not the same as exploitable
Compare your product and version with the public record. A matching version still requires validation against your environment.
Is a vulnerable build present?
Compare these published version ranges with your installed build and any vendor patches.
