CVE-2025-66603 is a low-severity vulnerability in Yokogawa Electric Corporation's FAST/TOOLS software versions R9.01 to R10.04. The issue arises because the web server accepts the HTTP OPTIONS method, which can disclose information about supported HTTP methods. While this does not directly allow exploitation, it can aid attackers in reconnaissance and facilitate other attacks. The vulnerability does not require authentication but does require user interaction and has a high attack complexity, limiting its exploitability. There are no known exploits in the wild, and no patches have been released yet. European organizations using FAST/TOOLS in critical industrial control systems should be aware of this issue. Mitigations include restricting or disabling the OPTIONS method on the web server and monitoring for unusual HTTP requests. Countries with significant industrial automation sectors using Yokogawa products, such as Germany and the UK, may be more affected.
