The Fileserver web application in Apache ActiveMQ 5.x before 5.14.0 allows remote attackers to upload and execute arbitrary files via an HTTP PUT followed by an HTTP MOVE request.
The web-based administration console in Apache ActiveMQ 5.x before 5.13.2 does not send an X-Frame-Options HTTP header, which makes it easier for remote attackers to conduct clickjacking attacks via a crafted web page that contains a (1) FRAME or (2) IFRAME element.
Apache ActiveMQ 5.x before 5.13.0 does not restrict the classes that can be serialized in the broker, which allows remote attackers to execute arbitrary code via a crafted serialized Java Message Service (JMS) ObjectMessage object.
