An authenticated user can execute ALTER TABLE EXCHANGE PARTITIONS without being authorized by Apache Sentry before 2.0.1. This can allow an attacker unauthorized access to the partitioned data of a Sentry protected table and can allow an attacker to remove data from a Sentry protected table.
CWE-862 - Missing Authorization
The missing authorization vulnerability occurs when a software program allows users to access privileged parts of the program without verifying the user credentials. Impact of such a vulnerability depends on the resources employed by the software, ranging from account takeover to sensitive information exposure, denial of service, and complete system takeover.
