CWE-122Published: March 26, 2024· Updated: Jun 17, 2026
Official Description
A heap-based memory buffer overflow vulnerability in Rockwell Automation Arena Simulation software could potentially allow a malicious user to insert unauthorized code into the software by overstepping the memory boundaries, which triggers an access violation.
