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.

Synopsis

Anonymous authentication is allowed on the remote SMTP server.

Description

This SMTP service allows anonymous authentication. Any remote user may connect and authenticate without providing a password or unique credentials. This may effectively turn the remote server into an open mail relay.
