CVE-2023-22946

Severity CVSS v4.0:
Pending analysis
Type:
CWE-269 Improper Privilege Management
Publication date:
17/04/2023
Last modified:

Description

In Apache Spark versions prior to 3.4.0, applications using spark-submit can specify a &amp;#39;proxy-user&amp;#39; 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.<br /> <br /> Update to Apache Spark 3.4.0 or later, and ensure that <br /> spark.submit.proxyUser.allowCustomClasspathInClusterMode is set to its <br /> default of "false", and is not overridden by submitted applications.<br /> <br /> <br />
