Summary
A vulnerability in the RADIUS Policy API endpoints of Cisco ISE allows an authenticated, remote attacker with read-only Administrator privileges to gain unauthorized access to sensitive information. This is due to improper role-based access control (RBAC) permissions on these API endpoints.
Risk Assessment
The organization risks exposure of sensitive RADIUS Policy details, which could be leveraged for further attacks or network compromise. The attacker can bypass the web-based management interface and directly call the vulnerable endpoint.
