A MicroLogix 1100 programmable logic controller (PLC) has been detected which is vulnerable to a Denial of Service attack vector.
Rockwell Automation MicroLogix 1100 PLCs contain an unspecified flaw in the password mechanism that may allow a remote denial of service. The issue is only present when the HTTP server is enabled. This may allow a remote attacker to cause the program to crash.
Upgrade the firmware of MicroLogix 1100 L16xxx to 10.000 or later.
