Title:Cisco Nexus 3000 Series Switches SNMP Non-Existent OID Denial of Service Vulnerability (Cisco-SA-20150930-CVE-2015-6308)
Summary:A vulnerability in the Simple Network Management Protocol; (SNMP) interface of the Nexus 3000 (N3K) Series Switch could allow an authenticated, remote; attacker to cause a partial denial of service (DoS) condition to the SNMP service running on the; device.
Description:Summary:
A vulnerability in the Simple Network Management Protocol
(SNMP) interface of the Nexus 3000 (N3K) Series Switch could allow an authenticated, remote
attacker to cause a partial denial of service (DoS) condition to the SNMP service running on the
device.

Vulnerability Insight:
The vulnerability is due to improper handling of an SNMP
request with a non-existent Object Identifier (OID). An attacker could exploit this vulnerability
by sending a crafted SNMP request to the affected device.

Vulnerability Impact:
An exploit could allow the attacker to cause a partial DoS
condition of the SNMP interface where SNMP requests with legitimately formatted OIDs will time
out. The DoS condition does clear and SNMP requests will start to be processed normally as
expected.

Solution:
See the referenced vendor advisory for a solution.

CVSS Score:
4.0
