NNTP Service Cleartext Login Permitted

low Nessus Plugin ID 57335
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

The remote NNTP server allows cleartext logins.

Description

The remote host is running an NNTP server that advertises that it allows cleartext logins over unencrypted connections. An attacker may be able to uncover user names and passwords by sniffing traffic to the server if a less secure authentication mechanism (i.e. LOGIN or PLAIN) is used.

Solution

Configure the service to support less secure authentication mechanisms only over an encrypted channel.
