The DNP3 feature on Rockwell Automation Allen-Bradley MicroLogix 1400 1766-Lxxxxx A FRN controllers 7 and earlier and 1400 1766-Lxxxxx B FRN controllers before 15.001 allows remote attackers to cause a denial of service (process disruption) via malformed packets over (1) an Ethernet network or (2) a serial line.
