Detailsinfo

A vulnerability was found in Apache Spark up to 3.3.x. It has been declared as critical. This vulnerability affects an unknown code block of the component Configuration Handler. The manipulation with an unknown input leads to a privileges management vulnerability. The CWE definition for the vulnerability is CWE-269. The product does not properly assign, modify, track, or check privileges for an actor, creating an unintended sphere of control for that actor. As an impact it is known to affect confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was presented 04/17/2023. The advisory is shared for download at lists.apache.org. This vulnerability was named CVE-2023-22946 since 01/11/2023. There are neither technical details nor an exploit publicly available. The MITRE ATT&CK project declares the attack technique as T1068.
