To exploit this vulnerability, the attacker must have at least Read Only Admin credentials.\\r\\n\\r\\nThis 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 to\\u0026nbsp;root. 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.&#8221;,&#8221;published&#8221;:&#8221;2026-04-15T16:03:35.310Z&#8221;,&#8221;modified&#8221;:&#8221;2026-04-15T16:56:35.331Z&#8221;,&#8221;type&#8221;:&#8221;cve&#8221;,&#8221;title&#8221;:&#8221;Cisco
