FreeBSD : puppet6 -- Arbitrary Catalog Retrieval (77687355-52aa-11ea-b115-643150d3111d)

medium Nessus Plugin ID 134844

Language:

Synopsis

The remote FreeBSD host is missing a security-related update.

Description

Puppetlabs reports :

Previously, Puppet operated on a model that a node with a valid certificate was entitled to all information in the system and that a compromised certificate allowed access to everything in the infrastructure. When a node's catalog falls back to the `default` node, the catalog can be retrieved for a different node by modifying facts for the Puppet run. This issue can be mitigated by setting `strict_hostname_checking = true` in `puppet.conf` on your Puppet master.

Puppet 6.13.0 changes the default behavior for strict_hostname_checking from false to true. It is recommended that Puppet Open Source and Puppet Enterprise users that are not upgrading still set strict_hostname_checking to true to ensure secure behavior.

Solution

Update the affected package.
