Security News > 2023 > November > 3,000 Apache ActiveMQ servers vulnerable to RCE attacks exposed online
Over three thousand internet-exposed Apache ActiveMQ servers are vulnerable to a recently disclosed critical remote code execution vulnerability.
Apache ActiveMQ is a scalable open-source message broker that fosters communication between clients and servers, supporting Java and various cross-language clients and many protocols, including AMQP, MQTT, OpenWire, and STOMP. Thanks to the project's support for a diverse set of secure authentication and authorization mechanisms, it is widely used in enterprise environments where systems communicate without direct connectivity.
Researchers from threat monitoring service ShadowServer found 7,249 servers accessible with ActiveMQ services.
Of those, 3,329 were found to run an ActiveMQ version vulnerable to CVE-2023-4660, with all of these servers vulnerable to remote code execution.
