Command injection in org.apache.hadoop.fs.FileUtil.unTarUsingTar

Apache Hadoop's FileUtil.unTar(File, File) API does not escape the input file name before being passed to the shell. An attacker can inject arbitrary commands. This is only used in Hadoop 3.3 InMemoryAliasMap.completeBootstrapTransfer, which is only ever run by a local user. It has been used in Hadoop 2.x for yarn localization, which does enable remote code execution. It is used in Apache Spark, from the SQL command ADD ARCHIVE. As the ADD ARCHIVE command adds new binaries to the classpath, being able to execute shell scripts does not confer new permissions to the caller. SPARK-38305. "Check existence of file before untarring/zipping", which is included in 3.3.0, 3.1.4, 3.2.2, prevents shell commands being executed, regardless of which version of the hadoop libraries are in use. Users should upgrade to Apache Hadoop 2.10.2, 3.2.4, 3.3.3 or upper (including HADOOP-18136).

Apache Hadoop 操作系统命令注入漏洞

Apache Hadoop是美国阿帕奇（Apache）基金会的一套开源的分布式系统基础架构。该产品能够对大量数据进行分布式处理，并具有高可靠性、高扩展性、高容错性等特点。 Apache Hadoop存在操作系统命令注入漏洞，该漏洞源于其 FileUtil.unTar(File, File)应用程序接口未转义用户提交到shell的文件名导致攻击者可以注入任意命令。以下版本受到影响：2.0.0至2.10.1、3.0.0-alpha至3.2.3、3.3.0至3.3.2。
