Summary

  o Multiple vulnerabilities in the web-based management interface of Cisco
    Identity Services Engine (ISE) could allow an authenticated, remote
    attacker to conduct a stored cross-site scripting (XSS) attack against a
    user.

    These vulnerabilities exist because the web-based management interface does
    not sufficiently validate user-supplied input. An attacker could exploit
    these vulnerabilities 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 these vulnerabilities, the
    attacker would need valid administrative credentials.

    Cisco has released software updates that address these vulnerabilities.
    There are no workarounds that address these vulnerabilities.
