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.
Affected configurations
• apache hbase (< 2.5.15)
• apache hbase (>= 2.6.0 < 2.6.6)
• apache hbase 3.0.0
