Mitsubishi Electric Melsec Iq F Series Fx5 Enet Ip Ethernet Module Fx5 Enet Ip
Monthly
Denial-of-service in Mitsubishi Electric MELSEC iQ-F Series FX5-ENET/IP Ethernet Modules (all versions) allows unauthenticated remote attackers to halt the module's communication function by flooding its Ethernet port with packets. The high packet rate overwhelms internal anomaly-detection processing and stops communications - a critical impact for the industrial control environments these PLCs operate in. No public exploit identified at time of analysis, but the CVSS 4.0 score of 8.7 reflects high availability impact in operational technology contexts.
