Rockwell Automation Arena

An attacker with network access to Arena could trigger a memory corruption flaw that causes the application to crash or potentially execute arbitrary code, disrupting engineering workflow and plant modeling operations.

Engineering and planning teams that use Rockwell Arena for process modeling, plant design, and simulation. This impacts design and engineering departments rather than production operations directly, but disruption could delay commissioning or changes to production systems.

An attacker on the network sends a specially crafted request or input to an Arena instance, triggering the memory corruption flaw. If network segmentation is weak, this could be done from an external network or a compromised workstation on the same subnet. Successful exploitation could crash the application or allow code execution depending on the memory layout.
