Synopsis
The remote device is missing a vendor-supplied security patchDescription
According to its self-reported version, the packet processing functionality of Cisco Firepower Threat Defense (FTD) Software is affected by TCP flood denial of service vulnerability due to inefficient memory management. An unauthenticated, remote attacker can exploit this by sending a large number of TCP packets to a specific port on an affected device. A successful exploit could allow the attacker to exhaust system memory, which could cause the device to reload unexpectedly. No manual intervention is needed to recover the device after it has reloaded.Please see the included Cisco BID 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 number.
