An issue was discovered in Cobbler before 3.3.1. Files in /etc/cobbler are world readable. Two of those files contain some sensitive information that can be exposed to a local user who has non-privileged access to the server. The users.digest file contains the sha2-512 digest of users in a Cobbler local installation. In the case of an easy-to-guess password, its trivial to obtain the plaintext string. The settings.yaml file contains secrets such as the hashed default password.
During installation, installed file permissions are set to allow anyone to modify those files.
