Issue #1590 has been updated by jerico.
One more comment: The alternative solution is not so good protection as a potential attacker who gained puppet user privileges could still read/copy the private key from disk and thereby produce correct authentication. Otherwise he'd have to access memory in some way which is more difficult (and AFAIK inevitable). ---------------------------------------- Bug #1590: wrong permissions/ownership for ca key http://projects.reductivelabs.com/issues/show/1590 Author: jerico Status: Unreviewed Priority: Urgent Assigned to: Category: SSL Target version: 0.24.4 Complexity: Medium Affected version: 0.24.4 Keywords: The default puppet ca is poorly protected. Much of the use of running puppetmasterd as a dedicated user is lost as sensitive ca files (=password, key, crl) establishing encryption and authentication/authorization are writeable by the puppet user by default. -rw-rw---- 1 puppet puppet ca_key.pem -rw-rw-r-- 1 puppet puppet ca_crl.pem -rw-rw---- 1 puppet puppet ca.pass There are two problems with this setup: These files should have root ownership and they should not be writeable by puppetmasterd at runtime. Somebody achieving control through a 0-day bug in the puppetmasterd process will be able to work around encryption, authentication and authorization. IMO this issue is a potential remote exploit and therefore critical. IMO best fix: Start puppetmasterd with root privileges, read (or create) the files, then downgrade to configured low-privilege user as soon as possible. This is a practice implemented by many high profile daemons (e.g. apache2, openvpn, ...) and can be easily combined with a chroot strategy. Alternatively: Create a root level admin tool that creates the CA and PKI with root:puppet ownership and 640 permissions. ---------------------------------------- You have received this notification because you have either subscribed to it, or are involved in it.
