Description
A vulnerability in the IP Access Restriction feature of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to bypass configured IP access restrictions and log in to the device from a disallowed IP address. This vulnerability is due to improper enforcement of access controls that are configured using the IP Access Restriction feature.
