Synopsis
The remote device is missing a vendor-supplied security patchDescription
The version of Cisco Firepower Management Center (FMC) installed on the remote host is prior to 6.6.1. It is, therefore, affected by a vulnerability in the dashboard widget that allows an authenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper restrictions on XML entities. An attacker could exploit this vulnerability by crafting an XML-based widget on an affected server. A successful exploit could cause increased memory and CPU utilization, which could result in a DoS condition.Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
