# CVE-2023-22946

> 6.4 MEDIUM

## Beschreibung

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 "false", and is not overridden by submitted applications.
