Cisco Identity Services Engine Multiple Vulnerabilities (cisco-sa-ise-rce-4fverepv)
critical Nessus Plugin ID 306554
Synopsis
The remote device is missing a vendor-supplied security patch.Description
According to its self-reported version, Cisco ISE is affected by multiple vulnerabilities.- A vulnerability in Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to execute arbitrary commands on the underlying operating system of an affected device. To exploit this vulnerability, the attacker must have at least Read Only Admin credentials. This vulnerability is due to insufficient validation of user-supplied input. An attacker could exploit this vulnerability by sending a crafted HTTP request to an affected device. A successful exploit could allow the attacker to obtain user- level access to the underlying operating system and then elevate privileges toroot. In single-node ISE deployments, successful exploitation of these vulnerabilities could cause the affected ISE node to become unavailable, resulting in a denial of service (DoS) condition. In that condition, endpoints that have not already authenticated would be unable to access the network until the node is restored.
(CVE-2026-20180, CVE-2026-20186)
