According to its self-reported version, Cisco Firepower Management Center is affected by multiple cross-site scripting (XSS) vulnerabilities in its web-based admin interface due to improper validation of user-supplied input before returning it to users. An unauthenticated, remote attacker can exploit these, by convincing a user to click a specially crafted URL, to execute arbitrary script code in a user’s browser session.
Please see the included Cisco BIDs and Cisco Security Advisory for more information.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version
