“The next kernel in the JDE.INI file is the Server Administration Workbench (SAW) kernel. This kernel is responsible for collecting and reporting information about the kernels in EnterpriseOne. The SAW kernel will connect to each of the kernels to determine information including:
- Number of users connected to the kernel (if applicable) - Number of requests processes by the kernel - Average time to complete the request - Outstanding requests - Users connected to the kernel process (if applicable)
This information is displayed in the SAW or Server Manager applications. This is critical to monitoring the health of the EnterpriseOne kernels and providing a view into how the system is executing .” JD Edwards EnterpriseOne. The complete reference. - Copyright © 2009 by The McGraw-Hill Companies
If a specially crafted packet is sent to the JDENet Service (6015 TCP by default), and the JDESAW Kernel is configured (it is by default), then it would be possible to read any file on the system.
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.
