-- Vulnerability Details:
This vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Oracle Applications Server. Authentication
is not required to exploit this vulnerability.

The specific flaw exists within the Oracle Process Manager and
Notification (opmn) daemon which is an HTTP daemon listening on a TCP
port above 6000. The daemon fails to properly handle format string
tokens in the POST URI when logging to the file
$ORACLE_HOME/opmn/logs/opmn.log. Exploitation of this issue can result
in arbitrary code execution.
