CVE-2023-22946 (GCVE-0-2023-22946)

Vulnerability from cvelistv5 – Published: 2023-04-17 07:30 – Updated: 2024-10-21 15:06
VLAI?
Summary
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.
Severity ?
