Descripción:	Summary: A vulnerability in certain access-control filtering mechanisms on Cisco Nexus 7000 Series Switches could allow an unauthenticated, remote attacker to bypass defined traffic configured within an access control list (ACL) on the affected system. Vulnerability Insight: The vulnerability is due to the device failing to inspect specific traffic when other ACL checking mechanisms are in place. An attacker could exploit this vulnerability by issuing crafted commands for which a particular ACL would not match defined traffic. Vulnerability Impact: An exploit could allow the attacker to bypass certain rulesets defined on a Network Time Protocol (NTP) ACL. Solution: See the referenced vendor advisory for a solution.
