-----------------------------
Summary: [Threat Modeling] Drillbit may be spoofed by an attacker
and this may lead to data being written to the attacker's target instead of
Drillbit
Key: DRILL-5582
URL: https://issues.apache.org/jira/browse/DRILL-5582
Project: Apache Drill
Issue Type: Bug
Affects Versions: 1.10.0
Reporter: Rob Wu
Priority: Minor
Consider the scenario:
Alice has a drillbit (my.drillbit.co) with plain and kerberos authentication
enabled containing important data. Bob, the attacker, attempts to spoof the
connection and redirect it to his own drillbit (fake.drillbit.co) with no
authentication setup.
When Alice is under attack and attempts to connect to her secure drillbit, she
is actually authenticating against Bob's drillbit. At this point, the
connection should have failed due to unmatched configuration. However, the
current implementation will return SUCCESS as long as the (spoofing) drillbit
has no authentication requirement set.
Currently, the drillbit <-to-> drill client connection accepts the lowest
authentication configuration set on the server. This leaves the user vulnerable
to spoofing.
