Apache ActiveMQ < 5.19.9 / 6.x < 6.2.8 Multiple Vulnerabilities

medium Nessus Plugin ID 330836

Synopsis

The remote host is running a web application that is affected by multiple vulnerabilities.

Description

The version of Apache ActiveMQ running on the remote host is prior to 5.19.9 or 6.x prior to 6.2.8. It is, therefore, affected by multiple vulnerabilities:

- Improper Input Validation vulnerability in Apache ActiveMQ AMQP, Apache ActiveMQ, Apache ActiveMQ All. A remote unauthenticated peer that can reach an exposed AMQP NIO connector can trigger denial-of-service behavior by sending a frame size value. This cause the NIO threads to die and if done rapidly enough can lead to exhaustion of the NIO thread pool denying service to other connections. (CVE-2026-59878)

- Improper Authorization vulnerability in Apache ActiveMQ Broker, Apache ActiveMQ All, Apache ActiveMQ. An authenticated low-privilege user can bypass a per-destination write ACL by sending to an ActiveMQ temporary composite destination whose physical name is a comma-separated composite of real queues. This allows publishing messages to any of the destinations in the list without proper write ACL permissions because the authorization check is bypassed due to the composite destination being marked as temporary. (CVE-2026-61487)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade to Apache ActiveMQ version 5.19.9, 6.2.8, or later.
