The version of Cisco Firepower Management Center installed on the remote host is affected by a directory traversal vulnerability as referenced in the cisco-sa-fmc-dir-traversal-95UyW5tk advisory. An authenticated, remote attacker can exploit this, by sending a crafted HTTPS request that contains directory traversal characters, to read arbitrary files on the device.
Note that Nessus has not tested for this issue but has instead relied only on the application’s self-reported version number.
