Splunk Universal Forwarder < 9.0 Insecure Default Configuration

high Nessus Plugin ID 164077

Synopsis

An application running on a remote web server host may be affected by an insecure default configuration.

Description

In universal forwarder versions before 9.0, management services are available remotely by default. When not required, it introduces a potential exposure, but it is not a vulnerability. If exposed, we recommend each customer assess the potential severity specific to your environment. In Splunk 9.0, the universal forwarder now binds the management port to localhost preventing remote logins by default.

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

Solution

Upgrade Splunk Universal Forwarder to version 9.0, or later.
