A vulnerability exists in multiple Mitsubishi Electric MELSEC PLC series where the authentication mechanism uses password hashes instead of the actual password for authentication. This allows a remote, unauthenticated attacker to capture a password hash via network eavesdropping and subsequently replay the hash to gain unauthorized access to the device. The affected products include all versions of MELSEC iQ-F, iQ-R, Q, and L series CPUs and communication modules as listed in the CVE description.
