Description Michael Kaplan 2020-09-29 14:35:02 UTC

Description:
When Kerberos authentication is enabled and SPNEGO through HTTP is not
enabled, any users can access some servlets without authentication.

Mitigation:
Users should upgrade to Apache Hadoop 2.10.0, 3.0.1 or upper. If you
are using the affected version of Apache Hadoop, you need to enable
SPNEGO through HTTP.


Versions affected:
3.0.0-alpha2 to 3.0.0, 2.9.0 to 2.9.2, 2.8.0 to 2.8.5

Comment 4 Przemyslaw Roguski 2020-10-05 11:13:02 UTC

In OpenShift Container Platform the hadoop-container uses Hadoop 3.1.1.redhat-00002 (hadoop 3.1.1 + patches).
Not affected by this flaw.

Comment 5 Przemyslaw Roguski 2020-10-05 11:13:07 UTC

Mitigation:

Users should upgrade to Apache Hadoop 2.10.0, 3.0.1 or upper. If it is not possible and affected version of Apache Hadoop is used,  SPNEGO through HTTP should be enabled.
