4. Affected Components Description

==================================

JDENet is a network communication middleware that performs network communications workstation-to-server and server-to-server. It is used to call

remote functions, to authenticate users and transmit information between hosts in a JD Edwards environment.

5. Vulnerability Details

========================

It is possible for a remote and unauthenticated attacker to retrieve passwords of users that are allowed to login to the SAW Kernel (System

Administration Workbench Kernel) in default installations of JD Edwards EnterpriseOne servers.

As SAW users are allowed to, among other things, remotely execute commands on the server, the exploitation of this vulnerability leads to a full

compromise of the server.

Further technical details about this issue are not disclosed at this moment with the purpose of providing enough time to affected customers to patch

their systems and protect against the exploitation of the

described vulnerability.
