A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to obtain sensitive information from network users that are outside the security group that the attacker is assigned to.  

This vulnerability exists because certain files lack proper authorization enforcement. An attacker with administrative privileges and management rights over network users could exploit this vulnerability by exporting the users. A successful exploit could allow the attacker to view passwords that are normally not visible to administrators.
