pulp.spec in the installation process for Pulp 2.8.3 generates the RSA key pairs used to validate messages between the pulp server and pulp consumers in a directory that is world-readable before later modifying the permissions, which might allow local users to read the generated RSA keys via reading the key files while the installation process is running.
client/consumer/cli.py in Pulp before 2.8.3 writes consumer private keys to etc/pki/pulp/consumer/consumer-cert.pem as world-readable, which allows remote authenticated users to obtain the consumer private keys and escalate privileges by reading /etc/pki/pulp/consumer/consumer-cert, and authenticating as a consumer user.
