Summary

  o A vulnerability in the web-based management interface of Cisco Firepower
    Management Center could allow an authenticated, 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 is due to insufficient validation of user-supplied input
    by the web-based management interface of an affected device. An attacker
    could exploit this vulnerability by first entering input within the
    web-based management interface and then persuading a user of the interface
    to view the crafted input within 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.

    There are no workarounds that address this vulnerability.
