VAR-201708-1569
Vulnerability from variot - Updated: 2022-05-17 01:50Allen-Bradley Micro850 is a programmable logic controller (PLC) from Rockwell Automation, Inc.
The Rockwell Allen-Bradley Micro850 PLC has a Gratuitous ARP denial of service vulnerability. By sending two consecutive ARP requests to the Micro850 PLC, the ARP Sender IP address and ARP Target IP address are both Micro850 PLC IP addresses. An attacker could exploit the vulnerability to cause the Micro850 PLC network. Failure, can not work normally, need to restart the PLC after power off to restore normal
