Description Nathan Kinder 2017-01-09 16:12:29 UTC
As a part of investigating bug#1351275, it was noticed that some of the default permissions on files that contain passwords (such as stackrc files) in a Director deployment are more open than they should be.  In particular, in the undercloud node:

/root/stackrc has root/root ownership and 600 permissions
/home/stack/stackrc has stack/stack ownership and 600 permissions
/home/stack/overcloudrc has stack/stack ownership and 664 permissions
/home/stack/undercloud-passwords.conf has stack/stack ownership and 664 permissions.

Items 1 and 2 are ok (600 permissions), but 3 and 4 should be locked down to 600.  This is not a vulnerability since /home/stack defaults to 700 permissions, but it should still be hardened to prevent accidental exposure of passwords if the permissions of /home/stack change in the future.

Comment 1 Rob Crittenden 2017-03-16 17:38:42 UTC
Both reviews have merged in their respective upstreams. Fix for both was to chmod 0600 the files.

This was merged into python-tripleoclient and instack-undercloud.
