Teams that run Apache ActiveMQ with its web console enabled are exposed. The attacker must be able to send messages as an authenticated producer, and an administrator must then browse the affected queue in the console. Brokers on the fixed versions, or without the web console, can skip it.
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.
