Rockwell Automation has issued a security advisory detailing two vulnerabilities affecting its Arena Simulation software. Disclosed by the Zero Day Initiative (ZDI), these flaws—tracked as CVE-2025-6376 and CVE-2025-6377—could allow attackers to achieve remote code execution (RCE) through specially crafted files.
Both vulnerabilities stem from improper handling of DOE (Design of Experiments) files. According to the advisory, “A crafted DOE file can force Arena Simulation to write beyond the boundaries of an allocated object.”
Exploitation of these flaws requires user interaction—such as opening a malicious file in Arena. But once triggered, the consequences can be severe.
“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.”
| Affected Product | CVE ID | First Affected Version | Patched in Version |
|---|---|---|---|
| Arena Simulation | CVE-2025-6376 | 16.20.08 and earlier | 16.20.09 and later |
| Arena Simulation | CVE-2025-6377 | 16.20.08 and earlier | 16.20.09 and later |
Rockwell urges users to upgrade to Arena version 16.20.09 or later. For organizations unable to update immediately, Rockwell advises applying security best practices, including:
- Avoid opening DOE files from untrusted sources.
- Limit user permissions to reduce the impact of code execution.
- Monitor file behavior and use endpoint protection tools.
More detailed mitigations are available on Rockwell’s official support page.
