Issue #1765 has been updated by IanTurner.
Luke, We don't have any puppet.conf file, and there is no node_name anywhere in /etc/puppet or /var/puppet, so I guess it's safe to assume we are running with defaults. However, we do see that changing the system hostname via the hostname command results in the puppetmaster downlading a different catalog, provided that on the client the old keys/certificates/etc filenames are copied to correspond to the new name. We have verified that the certificates properly contain the client CN, but puppetmaster is evidently ignoring it. Let me know if you can't reproduce this. --Ian ---------------------------------------- Bug #1765: Certificate hostnames are not verified http://projects.reductivelabs.com/issues/show/1765 Author: IanTurner Status: Needs design decision Priority: Normal Assigned to: Category: SSL Target version: Complexity: Hard Affected version: 0.24.6 Keywords: certificate security spoof validation authentication dns The puppetmaster only verifies the validity of the client certificate, but does not verify the associated hostname. Thus a client with a certificate signed as "publicserver" can instead claim to be "secretserver" and gain access to the latter's configuration. This certificate hostname spoofing can be a serious issue, since client configuration may include password hashes and other confidential data. The best approach to client validation is to verify that all three of the following are identical at the FQDN level: 1. The FQDN on the signed client certificate. 2. The FQDN presented by the client facter invocation. 3. The result of a reverse lookup on the connecting client IP address. Additionally, an address (A/AAAA record, not CNAME record) lookup on this FQDN should in turn yield the connecting client IP address in the query result. ---------------------------------------- You have received this notification because you have either subscribed to it, or are involved in it.
