Description

1. Cisco ISE Reflected XSS Vulnerability ( CVE-2025-20289   CVE-2025-20303   CVE-2025-20304   )

These vulnerabilities exist due to insufficient validation of user-supplied input by the web-based management interface of an affected system. An attacker could exploit these vulnerabilities by injecting malicious code into specific pages of the interface.

Successful exploitation of these vulnerabilities could allow the attacker to execute arbitrary script code in the context of the affected interface or access sensitive, browser-based information.

2. Cisco ISE Information Disclosure Vulnerability ( CVE-2025-20305   )

A vulnerability exists due to certain files lack proper data protection mechanisms. An attacker could exploit this vulnerability by performing actions where the results should only be viewable to a high-privileged user.
