Technical 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. 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.

Remediation

Check the references section for vendor advisories, patches, and mitigation guidance. If immediate patching is not possible, review the CVSS vector to understand the attack surface and apply compensating controls such as network segmentation or access restrictions.
