AFFECTED PRODUCTS AND SOLUTION

VULNERABILITY DETAILS

Rockwell Automation used the latest version of the CVSS scoring system to assess the following vulnerability. The vulnerability was reported by Zero Day Initiative (ZDI).

CVE-2025-6377 IMPACT

A remote code execution security issue exists in the affected product. 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.
