In Apache Hadoop 2.6.x before 2.6.5 and 2.7.x before 2.7.3, a remote user who can authenticate with the HDFS NameNode can possibly run arbitrary commands with the same privileges as the HDFS service.

Security readout for executives and security teams

This issue affects older Apache Hadoop deployments. An authenticated remote user with access to the HDFS NameNode could possibly run operating-system commands as the HDFS service account, creating risk to stored data, cluster integrity, and downstream analytics workloads. Exposure is most likely in legacy Hadoop clusters still running affected 2.6.x or 2.7.x releases, especially where the HDFS NameNode is reachable by many users, shared services, or broad internal networks. Prioritize remediation for internet-exposed, shared, or business-critical Hadoop clusters. The privilege level described could affect confidentiality and integrity, but urgency is tempered by the authentication requirement and lack of cited active exploitation. Mitigation focus: Upgrade Apache Hadoop 2.6.x to 2.6.5 or later.; Upgrade Apache Hadoop 2.7.x to 2.7.3 or later.; Restrict HDFS NameNode access to trusted users, hosts, and service accounts..
