An attacker could exploit this vulnerability by sending a crafted request to an affected system. A successful exploit could allow the attacker to manipulate the posture status on the affected system.

Cisco Identity Services Engine External Entity Injection Vulnerability

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.
