Rockwell Automation was made aware that the webservers of the Micrologix 1100 and 1400 controllers contain a vulnerability that may lead to a denial-of-service condition. The security vulnerability could be exploited by an attacker with network access to the affected systems by sending TCP packets to webserver and closing it abruptly which would cause a denial-of-service condition for the web server application on the device
