The Flex 5000 Ethernet Ip Adapter
Monthly
Remote denial-of-service in the Rockwell Automation FLEX 5000 EtherNet/IP adapter allows an unauthenticated network attacker to crash the module by sending a crafted CIP (Common Industrial Protocol) packet, halting the adapter and its associated I/O until a manual power cycle restores operation. The CVSS 4.0 score of 8.7 (High) reflects a network-reachable, no-privilege attack with high availability impact but no confidentiality or integrity loss. No public exploit identified at time of analysis, and the CVE is not listed in CISA KEV, so there is no confirmed active exploitation.
