CVE-2023-25696Network attack vector

Code execution via injected Beeline JDBC parameters

Published Feb 24, 2023 · Updated Oct 23, 2024

Improper input validation in Apache Airflow Hive Provider before 5.1.3 allows remote attackers to execute code through a crafted connection. The HiveCliHook _prepare_cli_cmd method inserts connection host, port, and schema fields into a Beeline JDBC URL without validating delimiter characters, allowing injected JDBC parameters. Exploitation requires a crafted Hive connection to reach the hook with Beeline enabled, and resulting code executes in the Airflow task context.
