CVE-2023-22946 — Vulnerability in org.apache.spark:spark-core_2.12...

CRITICAL

Apache Spark vulnerable to Improper Privilege Management

Published April 17, 2023Updated October 15, 2024Source: osv

Summary

In Apache Spark versions prior to versions 3.4.0 and 3.3.3, applications using spark-submit can specify a `proxy-user` to run as, limiting privileges. The application can execute code with the privileges of the submitting user, however, by providing malicious configuration-related classes on the classpath. This affects architectures relying on proxy-user, for example those using Apache Livy to manage submitted applications. Update to Apache Spark 3.4.0, 3.3.3, or later, and ensure that spark.submit.proxyUser.allowCustomClasspathInClusterMode is set to its default of "false", and is not overridden by submitted applications.
