Red Hat Satellite engineering is moving the tracking of its product development work on Satellite to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "Satellite project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs will be migrated starting at the end of May. If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "Satellite project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/SAT-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description Miroslav Suchý 2012-08-28 14:17:09 UTC 
Description of problem:

# ls -l /etc/candlepin/certs/
total 8
-rw-r--r--. 1 root katello 1834 Aug 28 04:44 candlepin-ca.crt
-rw-r-----. 1 root katello    1679 Aug 28 04:44 candlepin-ca.key
lrwxrwxrwx. 1 root katello   37 Aug 28 04:44 candlepin-upstream-ca.crt -> /etc/candlepin/certs/candlepin-ca.cr

Apache belongs to group katello, katello group can read candlepin-ca.key.
Therefore user apache can read private key of candlepin.
This can be exploited if attacker exploit apache.
I believe that we do not need apache to have access to this private key.

Version-Release number of selected component (if applicable):
katello-1.1.7-1.git.31.8662665.el6.noarch

 
I expect that 
  chown root:root /etc/candlepin/certs/candlepin-ca.key
would solve this situation.
Comment 1 Mike McCune 2012-08-29 15:18:35 UTC 
We use the cert+key in our apache conf for the default setup:

 grep candlepin /etc/httpd/conf.d/katello.conf 
  SSLCertificateFile /etc/candlepin/certs/candlepin-ca.crt
  SSLCertificateKeyFile /etc/candlepin/certs/candlepin-ca.key
  SSLCaCertificateFile /etc/candlepin/certs/candlepin-ca.crt

perhaps there is a better way to set this up so we don't have todo this
Comment 2 Lukas Zapletal 2012-08-30 13:53:29 UTC 
I wonder there is no other way. We need to use candlepin CA.
Comment 3 Bryan Kearney 2014-08-11 19:24:41 UTC 
I think we can close this:

[root@sat6 certs]# find / -name candlepin-ca.key
<EMPTY>

[root@sat6 certs]# pwd
/etc/pki/katello/certs
[root@sat6 certs]# ls -lah
