AI-Generated

Apache HBase is vulnerable due to a missing authorization check in its thrift and REST delegation service, allowing unauthorized users to access and manipulate scanner instances opened by others. This could lead to data leakage and unauthorized data manipulation, posing a risk to data integrity and confidentiality. Organizations utilizing affected versions (from 3.0.0-alpha-1 to 2.4.*) should prioritize upgrading to the patched versions to mitigate these risks.

Original NVD Description

Missing Authorization vulnerability in Apache HBase thrift and rest delegation service. A scan operation in thrift/rest service has 3 steps, open, fetch(possible multiple times), close. The open step will return an id which will be passed back to server for identifying the scanner instances stored at server side. We missed the owner check in fetch and close steps which means a user can fetch rows from the scanner which is opened by other users, and close scanners which belongs to other users. This issue affects Apache HBase:from 3.0.0-alpha-1 through 3.0.0-beta-1, from 2.6.0 through 2.6.5, from 2.5.0 through 2.5.14, through 2.4.*. Users are recommended to upgrade to version 3.0.0-beta-2, 2.6.6 and 2.5.15, which fixes the issue.
