Denial-of-service in the Rockwell Automation 1719-AENTR (and companion 1718-AENTR) EtherNet/IP adapter allows remote attackers to overload the device with a UDP unicast network storm, causing loss of communication that requires a manual power cycle to recover. The CVSS 4.0 score of 8.7 reflects a high availability impact reachable over the network with no privileges or user interaction. There is no public exploit identified at time of analysis and the flaw is not listed in CISA KEV, but the low attack complexity makes it a real operational-technology availability concern.
