New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote device is missing a vendor-supplied security patch.


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.
