CVSS medium 4.9

Overview

Description: A vulnerability in the ERS API of Cisco ISE could allow an authenticated, remote attacker to read arbitrary files on the underlying operating system of an affected device. To exploit this vulnerability, an attacker must have valid Administrator-level privileges on the affected device. This vulnerability is due to improper privilege management in the ERS API. An attacker could exploit this vulnerability by sending a crafted request to an affected device. A successful exploit could allow the attacker to elevate their privileges beyond the sphere of their intended access level, which would allow them to obtain sensitive information from the underlying operating system. Note: The ERS is not enabled by default. To verify the status of the ERS API in the Admin GUI, choose Administration > Settings > API Settings > API Service Settings.
