CVSS Score:


  o A vulnerability in the web-based management interface of Cisco Identity
    Services Engine (ISE) Software could allow an unauthenticated, remote
    attacker to conduct a cross-site scripting (XSS) attack against a user of
    the web-based management interface of an affected device.

    The vulnerability exists because the web-based management interface of the
    affected device does not properly validate user-supplied input. An attacker
    could exploit this vulnerability by persuading a user to click a crafted
    link. 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.

    Cisco has released software updates that address this vulnerability. There
    are no workarounds that address this vulnerability.
