CVE-2023-22946 Information

Description

In Apache Spark versions prior to 3.4.0 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 or later and ensure that spark.submit.proxyUser.allowCustomClasspathInClusterMode is set to its default of alse\ and is not overridden by submitted applications.
