4. Affected Components Description
================================ ==

"Oracle VM is server virtualization software which fully supports both Oracle and non-Oracle applications. Oracle VM 
offers scalable, low-cost server
virtualization that is three times more efficient than existing server virtualization products from other vendors. 
Oracle has also announced
certification of key Oracle products including Oracle Database, Oracle Fusion Middleware, Oracle Applications, and 
Oracle Real Application Clusters
with Oracle VM."

"Oracle VM Manager communicates with Oracle VM Agent to create and manage guests on an Oracle VM Server. Oracle VM 
Agent is installed and configured
during the installation of Oracle VM Server."

By default, Oracle VM Agent is executed, with a highly privileged user, typically root.


5. Vulnerability Details
=========================

Oracle VM Agent exposes several functions through XML-RPC. The use of some of these functions (executed as a highly 
privileged user, or root),  can
lead to an arbitrary file access which is not a valid function of the agent.

Onapsis is not distributing technical details about this issue to the general public at this moment in order to provide 
enough time to affected
customers to patch their systems and protect against the exploitation of the described vulnerability.


6. Solution
===========
