CVE-2025-3755
Estado: AplazadaCrítica (9.1)—
Improper Validation of Specified Index, Position, or Offset in Input vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series CPU modules allows a remote unauthenticated attacker to read information in the product, to cause a Denial-of-Service (DoS) condition in MELSOFT connection, or to stop the operation of the CPU module (causing a DoS condtion on the CPU module), by sending specially crafted packets. The product is needed to reset for recovery.
