About this tag
CVE-2025-7405 is a vulnerability affecting Mitsubishi Electric's MELSEC iQ-F series CPU modules, specifically in their Modbus/TCP handling. The flaw allows unauthenticated remote attackers to read and write device values and, in some deployments, halt program execution. CISA published an advisory on August 28, 2025, assigning a CVSS v4 base score of 6.9. Mitsubishi Electric recommends network-level mitigations rather than an immediate firmware replacement. This vulnerability is part of a broader set of nine ICS advisories released by CISA on the same date, covering critical vulnerabilities across multiple vendors including Schneider Electric, Delta Electronics, and GE Vernova. Operators are urged to prioritize patching and network hardening to secure industrial control systems.
