Rockwell Automation Logix 5370 and 5570 Controllers Vulnerable To Denial of Service Via CIP

A denial of service security issue exists in the

affected product. The security issue stems from a fault occurring when a

crafted CIP message is sent. Devices with less memory are more likely to be

affected. This can result in a major nonrecoverable fault (MNRF). A program

download is required to recover.
