Cloudera Manager 4.x, 5.0.x before 5.0.6, 5.1.x before 5.1.5, 5.2.x before 5.2.5, and 5.3.x before 5.3.3 uses global read permissions for files in its configuration directory when starting YARN NodeManager, which allows local users to obtain sensitive information by reading the files, as demonstrated by yarn.keytab or ssl-server.xml in /var/run/cloudera-scm-agent/process.
