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.

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. 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.

Cisco has confirmed the vulnerability. However, software updates are not available.

To exploit this vulnerability, an attacker must authenticate to the targeted device. This access
requirement reduces the likelihood of a successful exploit.

Cisco indicates through the CVSS score that functional exploit code exists. However, the code is not
known to be publicly available.

Solution:
See the referenced vendor advisory for a solution.

CVSS Score:
4.0

CVSS Vector:
AV:N/AC:L/Au:S/C:N/I:N/A:P
