The Kerberos/MapReduce security functionality in Apache Hadoop 0.20.203.0 through 0.20.205.0, 0.23.x before 0.23.2, and 1.0.x before 1.0.2, as used in Cloudera CDH CDH3u0 through CDH3u2, Cloudera hadoop-0.20-sbin before 0.20.2+923.197, and other products, allows remote authenticated users to impersonate arbitrary cluster user accounts via unspecified vectors.

Security readout for executives and security teams

This flaw lets an authenticated Hadoop user impersonate other cluster accounts in affected Kerberos/MapReduce deployments. For an organization still running these legacy Hadoop or Cloudera versions, it could undermine job ownership, data access controls, and audit integrity across the cluster. Exposure is likely limited to legacy Hadoop clusters using the affected Apache or Cloudera versions with Kerberos/MapReduce security enabled. Modern, upgraded Hadoop environments are less likely affected, but inherited analytics platforms and long-lived internal clusters should be checked. Prioritize if any legacy Hadoop or CDH3 clusters remain in production or hold sensitive data. The main business risk is trusted-user abuse leading to unauthorized access or misleading audit trails. Mitigation focus: Inventory Hadoop and Cloudera cluster versions against the affected ranges.; Upgrade Hadoop 0.23.x to 0.23.2 or later where applicable.; Upgrade Hadoop 1.0.x to 1.0.2 or later where applicable..
