SYNTHESIS OF THE VULNERABILITY
An attacker can send a malicious SNMP packet with a non-existent
OID to Cisco Nexus 3000, in order to trigger a denial of service.
– Impacted products: Cisco Nexus, NX-OS.
– Severity: 2/4.
– Creation date: 01/10/2015.
DESCRIPTION OF THE VULNERABILITY
The Cisco Nexus 3000 product has a service to manage received SNMP
packets.
However, when a packet with a non-existent OID (Object Identifier)

An attacker can therefore send a malicious SNMP packet with a
non-existent OID to Cisco Nexus 3000, in order to trigger a denial
of service.
