Does that headline sound fishy? Actually, Diff and Merge (WinMerge, to be exact) were my last resort in this disaster scenario. The final outcome could be told quite shortly, though this scenario serves as a good example how Murphy might hit you anytime… but first things first:

Although it’s a few days old, I’d like to point out an article by my colleague Markus Knies who had to deal with this vulnerability right on day zero:
Oracle released the quarterly critical patch updates on April 16th, 2019. Only one week later a zero-day vulnerability was identified by the KnownSec-404 security team. The vulnerability exists in Oracle Weblogic Server and has been labeled as CVE-2019-2725 and is also reported by the BSI (Bundesamt für Sicherheit in der Informationstechnik, Zero-Day-Schwachstelle in Oracle WebLogic Server, 25.04.2019).
Affected modules for this vulnerability are the wls9_async_response package with its components wls9_async and wls-wsat. With the help of these two modules it is possible to execute malicious content with elevated privileges.
Oracle reacted fast, broke the regular patch process, and launched an independent emergency patch on April 26th,2019:
Oracle reports that there is only an impact at the following versions: Oracle WebLogic Server, versions 10.3.6.0 and 220.127.116.11.
The BSI announces that all versions of Oracle WebLogic-Server are affected (also including the currently actual version 18.104.22.168).
The vulnerability CVSS score for this issue is 9.8. It is highly recommended to install this patch as soon as possible in affected systems.

For quite some time I planned to write a short series about automatically deploying Oracle Servers with Ansible – particularly with the module “ansible-oracle“. My Time Thieves didn’t allow that, so today, on ODC Appreciation Day, let me give this short rave on the great contribution by Mikael Sandström to our community!
