CVE-2025-1384Network attack vector

Unauthenticated remote code execution

Published Jul 13, 2025 · Updated Jul 14, 2025

Least privilege violation in communications between OMRON NJ/NX controllers and Sysmac Studio allows remote attackers to execute code. OMRON has not disclosed the precise communications locus or the operation that grants controller privileges beyond those intended. Exploitation requires no authentication but has high attack complexity; successful access permits arbitrary controller operations, including unauthorized code execution.
