EPSS · scored 2026-10-27

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to bypass the authorization mechanisms for specific administrative functions. This vulnerability is due to insufficient authorization enforcement mechanisms for users created by SAML SSO integration with an external identity provider. An attacker could exploit this vulnerability by submitting a series of specific commands to an affected device. A successful exploit could allow the attacker to modify a limited number of system settings, including some that would result in a system restart. In single-node Cisco ISE deployments, devices that are not authenticated to the network will not be able to authenticate until the Cisco ISE system comes back online.
