CVE-2020-1937Network attack vector

Authenticated SQL injection via unbound cube name

Published Feb 24, 2020 · Updated Aug 4, 2024

SQL injection in Apache Kylin allows remote authenticated users to run malicious database queries through crafted REST API input. CubeService directly interpolates the attacker-controlled cubeName into metrics queries in three cuboid-statistics methods instead of binding it as a parameter. A valid Kylin account is required, and successful injection can disclose or alter database data and interrupt service.
