 Mulesoft ESB Runtime 3.5.1 allows any arbitrary authenticated user to
create an administrator user due to a lack of permissions check in the
handler/securityService.rpc endpoint. The following HTTP request can be
made by any authenticated user, even those with a single role of Monitor.
 
 
 POST /mmc-3.5.1/handler/securityService.rpc HTTP/1.1

 This request will create an administrator with all roles with a username
of notadmin and a password of notpassword. Many vectors of remote code
execution are available to an administrator. Not only can an administrator
deploy WAR applications, they can also evaluate arbitrary groovy scripts
via the web interface.
