CVE-2019-12637: Cisco Identity Services Engine

Medium severity, CVSS 5.4. EPSS: 0.6% chance of exploitation in the next 30 days.

Multiple vulnerabilities in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to conduct cross-site scripting (XSS) attacks against a user of the web-based management interface. The vulnerabilities are due to insufficient validation of user-supplied input that is processed by the web-based management interface. An attacker could exploit these vulnerabilities by persuading a user of the interface to click a crafted link. A successful exploit could allow the attacker to execute arbitrary script code in the context of the interface or access sensitive, browser-based information.
