# Apache ActiveMQ Improper Authorization vulnerability

Apache ActiveMQ's default Jetty settings did not restrict /admin/* paths in the Web Console to administrators. An authenticated low-privilege web console user can therefore reach administrative pages they should not see.

_Summary, check and fix written by a model from the sources; labelled as such._

## Affected

- maven:org.apache.activemq:apache-activemq affected < 5.19.8 fixed 5.19.8
- maven:org.apache.activemq:apache-activemq affected >= 6.0.0, < 6.2.7 fixed 6.2.7
- vendor:apache activemq affected < 5.19.8 fixed 5.19.8
- vendor:apache activemq affected >= 6.0.0, < 6.2.7 fixed 6.2.7

## How to check

- Check the ActiveMQ version with `activemq --version` or the version in the broker's lib directory, and compare it with the affected ranges.
- Confirm whether the Web Console is enabled on the broker and whether low-privilege user accounts exist in its authentication configuration.

## Fix

- Apache ActiveMQ `5.19.8` for the 5.x line (affected before 5.19.8)
- Apache ActiveMQ `6.2.7` for the 6.x line (affected from 6.0.0 before 6.2.7)

## From the sources

Improper Authorization vulnerability in Apache ActiveMQ.

An authenticated low-privilege Web Console user by default can access /admin/* paths in the Web Console. The default Jetty settings incorrectly did not limit those paths to only admins.
This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7.

Users are recommended to upgrade to version 6.2.7 or 5.19.8, which fixes the issue.
