An issue was discovered in Cloudera Manager before 5.13.4, 5.14.x before 5.14.4, and 5.15.x before 5.15.1. A read-only user can access sensitive cluster information.
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.
Cloudera Navigator 2.2.x before 2.2.4 and 2.3.x before 2.3.3 include support for SSLv3 when configured to use SSL/TLS, which makes it easier for man-in-the-middle attackers to obtain cleartext data via a padding-oracle attack, a variant of CVE-2014-3566 (aka POODLE).
