high Nessus Plugin ID 348175
Synopsis
The remote device is missing a vendor-supplied security patch.Description
According to its self-reported version, Cisco ISE is affected by a vulnerability.- A vulnerability in the RADIUS feature of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper handling of certain RADIUS requests. An attacker could exploit this vulnerability by sending a crafted RADIUS request directly to an affected device. A successful exploit could allow the attacker to cause the ISE node to become unavailable. For single node deployments in that condition, endpoints that have not already authenticated would be unable to access the network until thenode comes back up on its own. (CVE-2026-20352)
