An exploitable denial of service vulnerability exists in the processing of snmp-set commands of the Allen Bradley Micrologix 1400 Series B FRN 21.2 and below. A specially crafted snmp-set request, when sent without associated firmware flashing snmp-set commands, can cause a device power cycle resulting in downtime for the device. An attacker can send one packet to trigger this vulnerability.
