The remote device is missing a vendor-supplied security patch


According to its self-reported version, Cisco Firepower Management Center is affected by a denial of service (DoS) vulnerability in its host input API daemon component due to improper certificate validation. An unauthenticated, local attacker can exploit this issue, by sending a crafted data stream to the host input daemon of an affected device, to impose a DoS condition.

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