CVE-2023-32007Network attack vector

Remote command execution via username impersonation

Published May 2, 2023 · Updated Feb 13, 2025

Command injection in Apache Spark 3.1.1 through 3.2.1 allows remote authenticated users to execute shell commands through the Spark UI. With ACLs enabled, HttpSecurityFilter accepts an arbitrary impersonated username that ShellBasedGroupsMappingProvider places in a bash -c command. The path requires an authentication filter and UI access, and commands run with the privileges of the Spark service account.
