A vulnerability in the Admin Portal of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to view saved passwords in plain text. The vulnerability is due to the incorrect inclusion of saved passwords when loading configuration pages in the Admin Portal. An attacker with read or write access to the Admin Portal could exploit this vulnerability by browsing to a page that contains sensitive data. An exploit could allow the attacker to recover passwords for unauthorized use and expose those accounts to further attack.
