1734 Point I O
Monthly
Remote denial-of-service in Rockwell Automation's 1734 POINT I/O module allows unauthenticated network attackers to force the module into a faulted state by sending specially crafted CIP (Common Industrial Protocol) messages, halting I/O processing until a manual restart is performed. The CVSS 4.0 base score of 8.7 reflects a high availability impact against a network-reachable OT device with no privileges or user interaction required. There is no public exploit identified at time of analysis, and the flaw is not listed in CISA KEV.
