Apache Kafka Vulnerable To Persistent Remote Denial Of Service Via Topic Names
Original release date: June 11, 2019
Last revised: ---
Source: TIBCO Software Inc.
Systems Affected
Apache Kafka versions 2.2.0 and below.
TIBCO Messaging - Apache Kafka Distribution - Core - Community Edition
versions 2.1.0 and below
TIBCO Messaging - Apache Kafka Distribution - Core - Enterprise Edition
versions 2.1.0 and below
The following component is affected:
* Topic management
Description
The component listed above contains a vulnerability that theoretically allows
a user with permission to create topics which will trigger an unexpected
server process exit. With the specially crafted topic names, when the server
deletes at user request, discards according to retention policy, or
repartitions, it is theoretically possible that the server will terminate
unexpectedly.
Impact
The impact of this vulnerability includes the theoretical possibility that
a malicious user could unexpectedly terminate a cluster of Kafka server
processes. The possibility exists that attempts to restart the server will
also fail.
