CVE-2025-66600

High
Published: Translated: NVD NIST

Summary

A vulnerability has been found in FAST/TOOLS by Yokogawa Electric Corporation due to missing HSTS (HTTP Strict Transport Security) configuration. An attacker performing a man-in-the-middle (MITM) attack could sniff communications with the web server. Affected packages: RVSVRN, UNSVRN, HMIWEB, FTEES, HMIMOB, versions R9.01 to R10.04.

Risk Assessment

The lack of HSTS allows an attacker to intercept and potentially modify network traffic between users and the web server, potentially leading to data leakage or session integrity compromise. The organization is exposed to industrial espionage or process manipulation.

Recommendation

Enable and configure the HSTS header on the FAST/TOOLS web server and update to the latest available version if the vendor provides a patch. Also consider implementing additional MITM protections such as verified TLS certificates.
