A vulnerability in the RADIUS Policy API endpoints of Cisco ISE could allow an authenticated, remote attacker with read-only Administrator privileges to gain unauthorized access to sensitive information on an affected device.
Does this matter?
Lower severity and a low EPSS score (0.22%). Track it; it rarely justifies an emergency change on its own.
Description
A vulnerability in the RADIUS Policy API endpoints of Cisco ISE could allow an authenticated, remote attacker with read-only Administrator privileges to gain unauthorized access to sensitive information on an affected device. This vulnerability is due to improper role-based access control (RBAC) permissions on the RADIUS Policy API endpoints. An attacker could exploit this vulnerability by bypassing the web-based management interface and directly calling an affected endpoint. A successful exploit could allow the attacker to gain unauthorized read access to sensitive RADIUS Policy details that are restricted for their role.
