Overview

The authorization framework in Apache Hive 1.0.0, 1.0.1, 1.1.0, 1.1.1, 1.2.0 and 1.2.1, on clusters protected by Ranger and SqlStdHiveAuthorization, allows attackers to bypass intended parent table access restrictions via unspecified partition-level operations.

Apache Hive 1.0.1 / 1.1.0 / 1.2.1 Authorization Bug Disclosure
Posted Jan 29, 2016
Authored by Sushanth Sowmyan, Olaf Flebbe

Some partition-level operations exist that do not explicitly also authorize privileges of the parent table. This can lead to issues when the parent table would have denied the operation, but no denial occurs because the partition-level privilege is not checked by the authorization framework, which defines authorization entities only from the table level upwards. This issue is known to affect Hive clusters protected by both Ranger as well as SqlStdHiveAuthorization. Apache Hive versions 1.0.0 through 1.0.1, 1.1.0 through 1.1.1, and 1.2.0 through 1.2.1 are affected.
