Executive brief
Rockwell Automation Arena Simulation, a software tool used to model and optimize complex industrial systems, is affected by a memory corruption vulnerability. An attacker could exploit this by tricking a user into opening a specially crafted malicious file. Successful exploitation could allow the attacker to take control of the user's system, potentially leading to data theft or disruption of simulation operations.
Technical details
A memory corruption vulnerability exists in the expmt.exe (Siman) component of Rockwell Automation Arena Simulation due to improper validation of user-supplied data. This flaw results in an out-of-bounds write (CWE-787). The attack vector is local and requires user interaction, specifically convincing a user to open a malicious file. If successfully exploited, an attacker can execute arbitrary code in the context of the current process. The vulnerability is addressed in version V17.00.01.
