VAR-201603-0334
Vulnerability from variot - Updated: 2022-05-17 02:01Rockwell Automation PLC Micro Logix 1200 is an integrated controller for processors, power supplies, and embedded input and output points.
Rockwell Automation PLC Micrologix 1200 uses EthernetIP protocol for industrial control communication. When the length field value of the EthernetIP protocol "NOP" message that communicates with Micrologix 1200 is set to 0x00945, and the connection is repeatedly established with it, the Ethernet protocol stack crashes, but the ping is still reachable. You need to shut down and restart to restore the EtherNetIP service. Allows an attacker to use this vulnerability to launch a denial of service attack
