CVE-2024-20251: Cisco Identity Services Engine

Medium severity, CVSS 5.4. EPSS: 0.4% chance of exploitation in the next 30 days.

A vulnerability in the web-based management interface of Cisco Identity Services Engine (ISE) could allow an authenticated, remote attacker to perform a stored cross-site scripting (XSS) attack against a user of the interface on an affected device. This vulnerability exists because the web-based management interface does not properly validate user-supplied input. An attacker could exploit this vulnerability by injecting malicious code into specific pages of the interface. A successful exploit could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.
