DescriptionCVE.org

A remote code execution security issue exists in the Rockwell Automation Arena®.  A crafted DOE file can force Arena Simulation to write beyond the boundaries of an allocated object. Exploitation requires user interaction, such as opening a malicious file within the software. If exploited, a threat actor could execute arbitrary code on the target system. The software must run under the context of the administrator in order to cause worse case impact. This is reflected in the Rockwell CVSS score, as AT:P.

Technical ContextAI

Remote code execution allows an attacker to run arbitrary commands or code on the target system over a network without prior authentication. This vulnerability is classified as Improper Input Validation (CWE-20).

RemediationAI

Apply vendor patches immediately. Restrict network access to vulnerable services. Implement network segmentation and monitoring for anomalous activity.
