A vulnerability in Cisco ISE and ISE-PIC could allow an unauthenticated, remote attacker to view sensitive information on an affected device. This vulnerability is due to improper authorization checks when a resource is accessed. An attacker could exploit this vulnerability by sending crafted traffic to an affected device. A successful exploit could allow the attacker to gain access to sensitive information, including hashed credentials that could be used in future attacks.
