Detail
| A vulnerability in the Simple Network Management Protocol (SNMP) feature of the Cisco Nexus 4000 Series Switch could allow an authenticated, remote attacker to cause the device to unexpectedly reload, resulting in a denial of service (DoS) condition. The vulnerability is due to incomplete validation of an SNMP poll request for a specific MIB. An attacker could exploit this vulnerability by sending a specific SNMP poll request to the targeted device. An exploit could allow the attacker to cause the device to reload, resulting in a DoS condition. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
