CVE-2024-20487: identity services XSS — Fix

Description

A vulnerability in the web-based management interface of Cisco ISE could allow an authenticated, remote attacker to conduct a stored XSS attack against a user of the interface. This vulnerability is due to insufficient validation of user-supplied input by the web-based management interface of an affected system. 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. To exploit this vulnerability, the attacker must have at least a low-privileged account on an affected device.
