CVE-2023-32007: Apache Spark: Shell command injection via Spark UI

[Arnout Engelen <engelen () apache org>]

Severity: important

Affected versions:

- Apache Spark 3.1.1 before 3.2.2

Description:

** UNSUPPORTED WHEN ASSIGNED ** The Apache Spark UI offers the possibility to enable ACLs via the configuration option 
spark.acls.enable. With an authentication filter, this checks whether a user has access permissions to view or modify 
the application. If ACLs are enabled, a code path in HttpSecurityFilter can allow someone to perform impersonation by 
providing an arbitrary user name. A malicious user might then be able to reach a permission check function that will 
ultimately build a Unix shell command based on their input, and execute it. This will result in arbitrary shell command 
execution as the user Spark is currently running as. This issue was disclosed earlier as CVE-2022-33891, but 
incorrectly claimed version 3.1.3 (which has since gone EOL) would not be affected.

NOTE: This vulnerability only affects products that are no longer supported by the maintainer.

Users are recommended to upgrade to a supported version of Apache Spark, such as version 3.4.0.
