An arbitrary code execution vulnerability in Rockwell Automation Arena Simulation could let a malicious user insert unauthorized code into the software. This is done by writing beyond the designated memory area, which causes an access violation. Once inside, the threat actor can run harmful code on the system. This affects the confidentiality, integrity, and availability of the product. To trigger this, the user would unwittingly need to open a malicious file shared by the threat actor.
