Apache Spark: Shell command injection via Spark UI

** 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.

Apache Spark 命令注入漏洞

Apache Spark是美国阿帕奇（Apache）基金会的一款支持非循环数据流和内存计算的大规模数据处理引擎。 Apache Spark 3.4.0之前版本存在命令注入漏洞，该漏洞源于如果ACL启用后，HttpSecurityFilter中的代码路径可以允许通过提供任意用户名来执行模拟，这将导致任意shell命令执行。
