"According to its self-reported version, Cisco Firepower Extensible Operating System (FXOS) is affected by a cross-site
request forgery vulnerability. The vulnerability is due to insufficient CSRF protections for the FCM interface. An
unauthenticated, remote attacker can exploit this vulnerability by persuading a targeted user to click a malicious
link. A successful exploit can allow the attacker to send arbitrary requests that can take unauthorized actions on
behalf of the targeted user.

Please see the included Cisco BIDs and Cisco Security Advisory for more information.");
