"The version of Cisco Firepower Management Center installed on the remote host is prior to 6.7.0. It is, therefore,
affected by a vulnerability as referenced in the cisco-sa-fmc-infodisc-RJdktM6f advisory. Specifically, a vulnerability
in the storage of proxy server credentials of Cisco Firepower Management Center (FMC) could allow an authenticated,
local attacker to view credentials for a configured proxy server. The vulnerability is due to clear-text storage and
weak permissions of related configuration files. An attacker could exploit this vulnerability by accessing the CLI of
the affected software and viewing the contents of the affected files. A successful exploit could allow the attacker to
view the credentials that are used to access the proxy server.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
