# Apache ActiveMQ, Apache ActiveMQ Web Console vulnerable to Cross-site Scripting

The ActiveMQ web console's browse page renders a JMS message ID without sanitization. An authenticated producer can send a message whose ID contains script, which runs in an administrator's browser when they browse the queue.

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

## How to check

- Check the ActiveMQ version the broker runs; affected builds are `5.19.8` and earlier and `6.0.0` up to but not including `6.2.7`.
- Check whether the web console (activemq-web-console) is deployed on the broker.

## Fix

- Apache ActiveMQ: upgrade to `5.19.8` on the 5.x line or `6.2.7` on the 6.x line.
- Apache ActiveMQ Web Console: upgrade to `5.19.8` on the 5.x line or `6.2.7` on the 6.x line.

## From the sources

Improper Neutralization of Input During Web Page Generation ('Cross-site Scripting') vulnerability in Apache ActiveMQ, Apache ActiveMQ Web Console.

The browse page in the web console renders a message Id directly without sanitization. This allows an authenticated producer to send a message with a JMS message ID that has been crafted to contain HTML/JavaScript such that when an administrator browses the queue in the Web Console, the payload executes in their browser.
This issue affects Apache ActiveMQ: before 5.19.8, from 6.0.0 before 6.2.7; Apache ActiveMQ Web Console: 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.
