Improper Neutralization of Input During Web Page Generation in Apache Hadoop

CVE-2017-3161GHSA-qm7f-r83w-3p46

What to do

Vendor fix available. Upgrade each affected package to the fixed version on its release line (org.apache.hadoop:hadoop-client 2.7.0), redeploy, then verify what is actually installed.

This page has no inventory attached, so it cannot say whether you are affected. A vendor fix is not proof that your deployment is fixed.

# Patch Next advisory brief: CVE-2017-3161

Advisory: Improper Neutralization of Input During Web Page Generation in Apache Hadoop
IDs: CVE-2017-3161, GHSA-qm7f-r83w-3p46
Record: https://patchnext.com/advisories/cve-2017-3161 (revision 1, source checked 26 Oct 2026, 15:53 UTC)
Inventory: none attached. This brief comes from a public page and does not say whether any deployment is affected.
Severity: Medium (CVSS 6.1)
Exploitation: no confirmed exploitation recorded. Patch Next confirms exploitation only from CISA KEV.
Vendor response: Vendor fix available; fixed versions by package: org.apache.hadoop:hadoop-client 2.7.0. A vendor fix does not mean a deployment is fixed.

## Affected components
- Maven org.apache.hadoop:hadoop-client: affected <= 2.6.5; fixed in 2.7.0

## Suggested inspection (read-only)
- Maven org.apache.hadoop:hadoop-client: check the installed version with your package manager.

## Supported action
Upgrade each affected component to a fixed version on its release line. For a transitive dependency, upgrade the parent package or add an override or constraint, then regenerate the lockfile. Redeploy every environment that ran an affected version.

## Required regression checks
- Run the test suite and a production build.
- Exercise the features that depend on org.apache.hadoop:hadoop-client.
- Repeat the inspection and confirm that only fixed versions remain installed.

## Rollback considerations
- Keep the previous lockfile and deployment artifact. Rolling back reinstates the vulnerable version, so apply any documented mitigation while you fix forward.

## Unresolved questions
- Which deployments run an affected version?
- Exploitation status can change. Check again before lowering the priority.
- Mark the work resolved only after the fixed version is verified in production.

## Sources
- Verified: https://github.com/advisories/GHSA-qm7f-r83w-3p46 (GitHub-reviewed advisory GHSA-qm7f-r83w-3p46 lists affected ranges: Maven org.apache.hadoop:hadoop-client >=0 <=2.6.5)

Commands are suggestions: review each one before running it.
