Summary
A vulnerability in the Simple Network Management Protocol (SNMP) module of
Cisco NX-OS Software could allow an unauthenticated, remote attacker to access
sensitive information.
The vulnerability is due to a failure to respond to invalid requests in the
same manner when specifying a VLAN ID. An attacker could exploit this
vulnerability by making a large number of requests to the listening SNMP port
of an affected device. A successful exploit could allow the attacker to
enumerate VLANs that are configured on the affected device.
This vulnerability affects Cisco Nexus 5000 Series and Cisco Nexus 6000 Series
devices running an affected version of Cisco NX-OS Software.
Cisco would like to thank Ehab Hussein of IOActive for discovering and
reporting this vulnerability.
