Improper Authorization in org.apache.hbase:hbase

High severity GitHub Reviewed Published Apr 2, 2019 to the GitHub Advisory Database • Updated Jan 11, 2023

Package

maven org.apache.hbase:hbase (Maven)

Affected versions

>= 2.0.0, < 2.0.5
>= 2.1.0, < 2.1.4

Patched versions

2.0.5
2.1.4

Description

In all previously released Apache HBase 2.x versions (2.0.0-2.0.4, 2.1.0-2.1.3), authorization was incorrectly applied to users of the HBase REST server. Requests sent to the HBase REST server were executed with the permissions of the REST server itself, not with the permissions of the end-user. This issue is only relevant when HBase is configured with Kerberos authentication, HBase authorization is enabled, and the REST server is configured with SPNEGO authentication. This issue does not extend beyond the HBase REST server.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
