Assessed Risk Level: Medium
Previous versions of the README for the puppetlabs-firewall module contained examples of configurations using the `port` parameter instead of referencing `dport` and `sport`. Following these examples explicitly could result in firewall rules that are unintentionally permissive. It is recommended to always use the specific `dport` and `sport` parameters.
With the puppetlabs-firewall 1.7.1 release, the
port parameter is now deprecated and will be removed in the next major release.
If any manifests using puppetlabs-firewall's
firewall resource are configured to use the
port parameter, users should update those manifests to use the specific
sport parameters instead.
Thanks to Narayan Newton of Tag1 Consulting for responsibly disclosing this issue to us.
