What is CVE-2018-0209?

A security flaw exists in the Simple Network Management Protocol (SNMP) communication channel of the Cisco 550X Series Stackable Managed Switches. This issue allows an authenticated remote attacker to send a crafted stream of SNMP traffic that can cause the device to unexpectedly reload, resulting in a Denial of Service (DoS) situation. Recovery may necessitate a manual reboot of the device. The vulnerability arises from inadequate input throttling of incoming SNMP traffic over an internal interface.
