What the advisory describes

A vulnerability in an API of Cisco ISE and Cisco ISE-PIC could allow an authenticated, remote attacker to read specific files on the underlying operating system of an affected device. This vulnerability is due to improper restriction of XML external entity references. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to read specific files on the affected system that the underlying process has permission to access.

Source: EUVD (ENISA), in the words of the advisory.
