Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to read arbitrary files or conduct a server-side request forgery (SSRF) attack through an affected device. To exploit these vulnerabilities, an attacker must have valid Administrator credentials on the affected device. For more information about these vulnerabilities, see the Details section of this advisory.

Weakness
