The Apache Struts 2 vulnerability may impact you. Proof of concept code has been released on gethub and is actively being discussed in underground forums. No plugins are needed for this exploit. All the attacker needs is put together a url that will give access to the Apache Struts installation.
Here is a list of potential Oracle products that could be vulnerable. (this list is not exhaustive and I have not had time to validate every entry on this list)
This vulnerability was discovered August 22, 2018, and I have not been able to find a patch for it. Please do your research, if you are using Apache Struts 2, then keep a close eye for the patch, and once the patch is released, install it.
Known Attacks. There are two proof of concept attacks published on gethub.com. (I’m not posting the links for good reason.) and there are two known active attacks going on in the wild. ISC SANS and Netlab 360 is tracking attacks.
To Do: 1) Block port 7001 internally until patched.
This is an easily exploited flaw, that allows a user with low level privileges ( connect with network access via Oracle Net) can completely hijack the Oracle database. Affected versions 11.2.0.4, 12.1.0.2, 12.2.0.1, 18
BGOUG: 16-18.11.2018 (planned) Blockchain a primer. There is a lot of confusion about the blockchain. Blockchain is not crypto currency, block chain is the one part of the technology that makes crypto currency secure. We’ll chat about the technology and how to implement the technology.
BGOUG: 16-18.11.2018 (planned) The application of blockchain technologies to build faith and trust in thecriminal justice system. I’m excited about this one. We are going to go through a case study of securing e-justice systems using blockchain technology.
Here is a quick tip on Oracle privilege analysis. Frequently I want to find out all of the ways a user can get to an object for any privilege. DBA_TAB_PRIVS and DBA_ROLE_PRIVS are the two views I go to. I want to also see all the privileges that are granted on any object. This is good for starting at the user tracking privileges to the object, it’s also good for starting at an object and walking back to the user. This query does a pivot on the users and roles to get the path to the object and what privileges are associated with that path. ===========================================================================

Let’s start with some key facts. I learned this from my High School Civics teacher who made us learn a bit about journalism along with studying the Constitution.
Who: The Polish Oracle Users Group, hosted by some of the most awesome people you’ll ever want to get to know. The young lady in the blue jeans is Luiza Nowak; what Luiza says goes, she’s “The Boss.”
This team gets a lot done, they bring in the top speakers from all over the world. They work hard so everything goes smooth, everyone learns, and everyone has a good time.
What: The annual Oracle Users Group Conference. We will be talking about everything from Machine Learning, to Secure Coding and Information Security.
Why: That’s a pretty silly question. For me, it’s the opportunity to share what I know with a wide audience. This is one of those conferences where you are not only going to do a serious amount of learning from over 20 of the top speakers in the world. You will also have the opportunity to expand your network. You will definitively have a good time, Kamil will see to that.
How: Get here by plane, train or automobile. I’m told that tickets have already been sold out. But double check with the website, things do change.
When you get here, be sure to bring your thinking cap, your beer mug, and your sense of humor. You’ll need em’. Zobaczcie się za kilka tygodni.
There is a mistake that I’m seeing frequently. Loading a raw data file into an encrypted database then leaving the data file on an unencrypted device.
After loading the data into the database; if you don’t need the data file anymore, you should do a secure delete on the file. If you are going to need the data file again, then move the data file to an encrypted device then do a secure delete on the old data file. Better yet, when you bring the data file down, save it straight to an encrypted device and work from that device.
