This is Kurt from Product Security, just to let you know we're keeping an eye on this and I'll be talking to the Satellite 6 people about it. Thanks for reporting this!
Comment 2 Kurt Seifried 2016-02-09 13:04:03 EST
So restricting HTTP methods/verbs:

<Location "/">
   AllowMethods GET POST...

This does not affect Trace, so we’ll also need:

TraceEnable Off
Comment 6 Bryan Kearney 2016-07-08 16:48:53 EDT
Per 6.3 planning, moving out non acked bugs to the backlog
Comment 9 Stephen Benjamin 2016-10-13 11:42:49 EDT
We have a few requests like this, and there may be other needs for custom apache settings.  I think the best approach would be allowing the customer to provide their own Hiera configruation for apache, like this one:


That way we can let them configure it in whatever way meets their security needs.

Comment 14 Stephen Benjamin 2016-10-20 13:44:16 EDT
Opened a PR upstream with a proposal on how to solve this.

Satellite 6.3 installer allows the use of hiera, so you can now "reach" into puppet classes that are not exposed at the top of satellite-installer and configure those deeper settings.  The PR adds support for some custom hiera config.

However, a warning: we have to be careful here - there are many settings that users should NOT change, so it should be documented on a case-by-case basis.

The ones mentioned here and in the linked BZ's should be safe to change and in general the various security guides recommend settings we don't care about too much (turning trace off, server signature, etc).

If the PR is accepted, users would:

Create a YAML file on the Satellite server:


With contents like this:

    apache::server_tokens: Prod
    apache::server_signature: Off
    apache::trace_enable: Off

This will configure the relevant apache settings.  Additional settings can be viewed in the code itself, or the apache module docs: https://forge.puppet.com/puppetlabs/apache

The names are usually fairly obvious.

After creating this file, re-run the installer and see Apache is configured accordingly:

[root@test-box foreman.hiera]# grep -r ServerSignature /etc/httpd
/etc/httpd/conf.d/15-default.conf:  ServerSignature Off
/etc/httpd/conf.d/03-crane.conf:  ServerSignature Off
/etc/httpd/conf.d/05-foreman.conf:  ServerSignature Off
/etc/httpd/conf.d/05-foreman-ssl.conf:  ServerSignature Off
/etc/httpd/conf/httpd.conf:ServerSignature Off

[root@test-box foreman.hiera]# grep -r ServerToken /etc/httpd
/etc/httpd/conf/httpd.conf:ServerTokens Prod

[root@test-box foreman.hiera]# grep -r Trace /etc/httpd
/etc/httpd/conf/httpd.conf:TraceEnable Off

Moving this bug to POST for triage into Satellite 6 since the upstream issue http://projects.theforeman.org/issues/16207 has been resolved.
Comment 16 Stephen Benjamin 2016-10-31 13:53:03 EDT
Upstream patch was accepted.  Steps are same as comment #14, except the path is more user-friendly:

Comment 17 Stephen Benjamin 2016-10-31 13:53:36 EDT

Just making the title clearer, since this works for anything (e.g. puppet) not just apache

QE: How To Verify This Bug

1. Edit the file /etc/foreman-installer/custom-hiera.conf to have this content:

apache::trace_enable: Off

2. Run satellite-installer

3. Confirm httpd config files have trace off

[root@test-box foreman.hiera]# grep -r Trace /etc/httpd
/etc/httpd/conf/httpd.conf:TraceEnable Off

@satellite-6.2.8-1.0.el7sat.noarch (snap3)

using reproducer in comment#26:

# cat /etc/foreman-installer/custom-hiera.conf
apache::trace_enable: Off

# satellite-installer -S satellite
Installing             Done                                               [100%] [...............................................................................................................................]
  * Satellite is running at https://<FQDN>
      Initial credentials are admin / ZMHdV5x3W3c6Y8KU
  * To install additional capsule on separate machine continue by running:

      capsule-certs-generate --capsule-fqdn "$CAPSULE" --certs-tar "~/$CAPSULE-certs.tar"

  The full log is at /var/log/foreman-installer/satellite.log

# grep -r Trace /etc/httpd
/etc/httpd/conf/httpd.conf:TraceEnable On

>>> custom param still has no effect
Comment 29 Lukas Pramuk 2017-02-23 17:50:24 EST

I noticed that reproducer in comment#26 is not correct: 
 custom-hiera.conf should be custom-hiera.yaml

# cat /etc/foreman-installer/custom-hiera.yaml
apache::trace_enable: Off

# satellite-installer -S satellite

# grep -r Trace /etc/httpd
/etc/httpd/conf/httpd.conf:TraceEnable Off

>>> installer takes custom param into account
