XSS in Cisco Identity Services Engine Software
CVE-2024-20539
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 exists because the web-based management interface does not sufficiently 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. To exploit this vulnerability, the attacker would need valid administrative credentials on an affected device.
