Open redirect vulnerability in Apache Ambari before 2.1.2 allows remote attackers to redirect users to arbitrary web sites and conduct phishing attacks via a URL in the targetURI parameter.

Apache Ambari 2.x before 2.4.0 includes KDC administrator passwords on the kadmin command line, which allows local users to obtain sensitive information via a process listing.

The agent in Apache Ambari before 2.1.2 uses weak permissions for the (1) /var/lib/ambari-agent/data and (2) /var/lib/ambari-agent/keys directories, which allows local users to obtain sensitive information by reading files in the directories.
