3,000 Apache ActiveMQ servers weak to RCE assaults uncovered on-line

Over three thousand internet-exposed Apache ActiveMQ servers are weak to a just lately disclosed crucial distant code execution (RCE) vulnerability.

Apache ActiveMQ is a scalable open-source message dealer that fosters communication between purchasers and servers, supporting Java and varied cross-language purchasers and lots of protocols, together with AMQP, MQTT, OpenWire, and STOMP.

Due to the venture’s help for a various set of safe authentication and authorization mechanisms, it’s extensively utilized in enterprise environments the place techniques talk with out direct connectivity.

Hundreds of servers unpatched

Researchers from risk monitoring service ShadowServer discovered 7,249 servers accessible with ActiveMQ companies.

Of these, 3,329 have been discovered to run an ActiveMQ model weak to CVE-2023-4660, with all of those servers weak to distant code execution.

Many of the weak situations (1,400) are situated in China. America comes second with 530, Germany is third with 153, whereas India, the Netherlands, Russia, France, and South Korea have 100 uncovered servers every.
