description
Cisco Identity Services Engine is affected by an authentication bypass in an API endpoint. An unauthenticated remote attacker who can reach the affected API may obtain unauthorized access to the device without using the normal web management login.
mitigation
Restrict access to ISE management and API interfaces to trusted administrative networks and limit untrusted network paths. Apply Cisco-provided remediation according to vendor guidance when it is available.
