A vulnerability in the web-based management interface of Cisco Identify Services Engine (ISE) could allow an authenticated, remote attacker to modify parts of the configuration on an affected device. This vulnerability is due to the lack of server-side validation of Administrator permissions. An attacker could exploit this vulnerability by submitting a crafted HTTP request to an affected system. A successful exploit could allow the attacker to modify descriptions of files on a specific page. To exploit this vulnerability, an attacker would need valid Administrator credentials.
