Severity: moderate 

Affected versions:

- Apache ActiveMQ (org.apache.activemq:apache-activemq) before 5.19.8
- Apache ActiveMQ (org.apache.activemq:apache-activemq) 6.0.0 before 6.2.7
- Apache ActiveMQ Web Console (org.apache.activemq:apache-web-console) before 
5.19.8
- Apache ActiveMQ Web Console (org.apache.activemq:apache-web-console) 6.0.0 
before 6.2.7

Description:

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.
