CVE-2021-27738: Improper Access Control to Streaming Coordinator & SSRF

Q: What is CVE-2021-27738?

CVE-2021-27738 is a vulnerability in Apache Kylin that allows an unauthenticated user to issue arbitrary requests on the `/kylin/api/streaming_coordinator/*` REST API endpoints.

First published: Thu Jan 06 2022(Updated: )

All request mappings in `StreamingCoordinatorController.java` handling `/kylin/api/streaming_coordinator/*` REST API endpoints did not include any security checks, which allowed an unauthenticated user to issue arbitrary requests, such as assigning/unassigning of streaming cubes, creation/modification and deletion of replica sets, to the Kylin Coordinator. For endpoints accepting node details in HTTP message body, unauthenticated (but limited) server-side request forgery (SSRF) can be achieved. This issue affects Apache Kylin Apache Kylin 3 versions prior to 3.1.2.
