DEFCON 17: Breaking the "Unbreakable" Oracle with Metasploit
 
39:08
Speakers: Chris Gates Member of the Metasploit Project Mario Ceballos Developer for the Metasploit Project Over the years there have been tons of Oracle exploits, SQL Injection vulnerabilities, and post exploitation tricks and tools that had no order, methodology, or standardization, mainly just random .sql files. Additionally, none of the publicly available Pentest Frameworks have the ability to leverage built-in package SQL Injection vulnerabilities for privilege escalation, data extraction, or getting operating system access. In this presentation we are going to present an Oracle Pentesting Methodology and give you all the tools to break the "unbreakable" Oracle as Metasploit auxiliary modules. We've created your version and SID enumeration modules, account bruteforcing modules, ported all the public (and not so public) Oracle SQL Injection vulnerabilities into SQLI modules (with IDS evasion examples for 10g/11g), modules for OS interaction, and modules for automating some of our post exploitation tasks.

Oracle Database 12c Security - Oracle Virtual Private Database (VPD)
 
12:29
Learn how to use Oracle Virtual Private Database (VPD) to secure your data. See all lessons at http://skillbuilders.com/12c-TSDP-Tutorial First, Virtual Private Database. What is it? Answer: It's a declarative technique for enforcing security. Typically, it's based on user application context. That was the first limitation of 8i. Backed with 8i context were session-specific. The context variables were sort in the PGA. That means you simply couldn't use this in a web environment. However, global context, with use of 9i, Virtual Private Database became usable for web applications with connection pooling. But whether you're using it to client server or on a three tier environment, it's declarative technique rather than a programmatic technique. I can go behind the back of the application as a DBA and generate predicates to get appended to all SQLs. Select, insert, update, delete the end users. Issue the SQL and I will generate a predicate that filters the access. It's impossible to bypass. All users will have predicates appended to all their code. It doesn't matter whether they're using SQL Plus, Discoverer, Business Objects, Crystal Reports, eBusiness Suites, whatever they're using, I as DBA can filter their access to roles. The end result, different users see different data sets while running the same code and accessing the same tables, hence, the name Virtual Private Database. Different users will think they're seeing a totally different set of tables, but in fact it's one column database, one set of tables hosting a single application shared by all the users. The mechanism - you can apply VPD to tables, to views, to synonyms, and a declarative technique. Once the technique you write a function that generates the predicate, you associate the function with the table. From then on whenever the user issue SQL against that table the Cost-Based Optimizer rewrites the code. The Cost-Based Optimizer rewrites the user SQL to call the function to generate the predicate. The predicate is then appended to the SQL and it's the modified SQL that is parsed and executed. Let's see how this actually works. I'm working here by the way. This is just a perfectly normal 12.1 database. But what I'm going to demonstrate at this point will in fact work on 11g as well. I'm not going to be using any of the 12c enhancements to VPD for this little demonstration. I'll work in the scott schema. What do we have to do? We write a function to generate the predicate string. Create function. And I'll my function vpdf. The function must conform to a fixed specification. It must take two varchar arguments. One of the arguments is intended to be the schema to which the function will be applied. The other argument is the object within the schema to which the function will be applied. And it must return a varchar2, which is the generated predicate. Let's begin. Within this function you can do just about anything. There are some limitations. It's impossible for the function to query or update the table against which the VPD calls here is going to be applied or we violate the rules of purity that we come across so often with PL/SQL. But apart from that, it can do just about anything - including a number of dreadful side effects can be introduced by writing VPD functions. I'm going to do a very simple one on this one. I'll shall simple return immediately a predicate. What predicate? Ename, which is the ename column from this scott.emp table. Ename should equal sys_context. I'll go to the local context, my user end context, and just extract session user. We can see that John has tested this earlier today and therefore the object already was suggesting and he's just dropping it now and cleaning up the recreate. I hope you realize these really are live demonstrations. I'm not just running scripts. I've created a function. What's that function going to do? It's going to return this value here. Test it. Always test it and see what it's actually going to do. I'll select vpdf. I have to give it a couple of arguments. This one will do for now.

Simplified DBA-018-User Privileges
 
13:21
A privilege is a right to execute a particular type of SQL statement or to access another user’s object. The Oracle database enables you to control what the users can and cannot do in the database. Privileges are divided into two categories: System privileges: Each system privilege allows a user to perform a particular database operation or class of database operations. For example, the privilege to create tablespaces is a system privilege. System privileges can be granted by the administrator or by someone who has been given explicit permission to administer the privilege. Object privileges: Object privileges allow a user to perform a particular action on a specific object, such as a table, view, sequence, procedure, function, or package. Without specific permission, users can access only their own objects. Object privileges can be granted by the owner of an object, by the administrator, or by someone who has been explicitly given permission to grant privileges on the object. For example, in our demo ERPUSER will own the tables and other users will require read, write object privileges on ERPUSER tables. Example Connect erpuser/welcome1 Grant insert on myable1 to user1; Grant insert on myable1 to user5 Create tablespace erp_data datafile ‘/u01/app/oradata/db11lin/erpdata01.dbf’ size 100M autoextend on; Create user erpuser identified by welcome1 default tablespace erp_data temporary tablespace temp; Grant connect, resource to erpuser; Create user user1 identified by welcome1 default tablespace erp_data temporary tablespace temp; Create table erpuser.mytable1 ( sno number(5), sname varchar2(20)); We can create a table for any user in this format if we have dba privileges. [owner.tablename] Connect user1/welcome1 Insert into erpuser.mytable1 values(100, ‘by user1’); Commit;

Oracle 12c PL/SQL Security Features - Lesson 4 of 8 - Roles and PLSQL
 
06:21
Learn how Roles really work with Oracle PL/SQL and why a privilege granted via a role can't be used in PL/SQL. Demonstrations, examples. See all lessons and many more free Oracle Database tutorials at https://www.skillbuilders.com/free-oracle-database-tutorials John Watson: We have the business of roles - roles and PL/SQL. The point here is that roles are invisible to PL/SQL. When you compile your code, only direct privileges are available. When you run your code, only direct privileges are available. This is for definer's rights, I should say. When you run the code, only direct privileges are available to grant to the definer. In effect, the definer's rights code, all roles are disabled within the stored procedure. And certainly roles are disabled when compiling the code. Functionally, it's equivalent to having issued the command SET ROLE NONE. Why is this? Why is it you can't use your privileges? It's perfectly straightforward. It's a technology limitation. Quickly to see what's going on. If I go in and say - let me connect or create a clear schema. I'll create myself, grant dba to jw identified by jw. I've created a user and given him ridiculously high privileges. Connect.... What can you do? You can do pretty much anything. If he wants to delete from scott.emp, he can do it. Let's roll back, because along with his dba role, he has the ability to pretty much anything to use the data. Now we'll create a procedure. If I create a procedure, create delemp as begin, and in there I delete from scott.emp, end, compilation errors. What are they? Show error. At line 2 table of view doesn't exist. That's line 2 delete from scott.emp. I remember way back in version 7, this cause so much confusion before we realized what was going on. It's quite simple that when we are within the code, as the definer or the invoker, because this is definer's rights code, when we are within the definer's rights code block or indeed when we are compiling a definer's rights code block, the roles are disabled and that's why we cannot see it. But why is this and why do I say it's a technology limitation? It's because roles can be enabled and disabled. They can be enabled or disabled. That makes it logically impossible to consider a role when executing a stored procedure because I might have the role enabled while I compile it, but how do I know that it's going to be enabled when I run it? If I grant execute on the code to a third party, he doesn't have the role at all and that he must not even be logged on. So it becomes a logical impossibility because of the way roles are used because roles are enabled or disabled. You can dynamically switch them on and off. It's a logical impossibility to use role within definer's rights program module. Invoker's rights code, however, is very different. That infuses some interesting issues. Invoker's rights code can use any roles that happen to be enabled for the user at the time that he invokes it in exactly the same way that an anonymous PL/SQL can use any enabled roles. In the security point of view, the definer can in effect grab any roles within his code that the invoker happens to have. Dave: [Question], John, pardon. How do you enable or disable a role? John: Right now there's several techniques. I won't spend too much time demonstrating. The easiest technique will be alter - I can set role none. And that will have disabled all my roles. Now if you look at this, I've got nothing. If I try to run my code and query - let's see. Yes. If I try to delete from scott.emp I can't see it. So I'll set role dba and now of course I can. That's the easiest way. In fact, there are much more [05:07 inaudible] ways to switch roles on and off. We can do it with operating system authentication and I can do it with proxy authentication. We have a persistent session through application server as well as a user when we pass that session out to many of the users that can switch roles on and off. That's the persistent session switch identities. Perhaps, best of all, I can create what I call secure application roles well it protect the role with a package and that can contest any number of issues - environment variables, maybe the time, maybe your IP address, perhaps the program you're using and switch roles on and off accordingly. So there are many ways for controlling roles and you should do it. Blindly granting roles and letting them be enabled all the time is not good security. The end result for this, however, you can get some pretty unexpected results within your code. I've tried to run through in our first half hour some of the issues that we see with PL/SQL in release 11g and earlier. After a short break, we'll move on to the 12c features.

Oracle 12c Grant Role to PL/SQL Procedures - Lesson 1 of 2
 
03:35
A great new security feature that can - among other things - prevent SQL injection and a multitude of other security vulnerabilities. In 12c you can make your PL/SQL code secure using a declarative technique. Simply grant a role to the PL/SQL code and add AUTHID CURRENT_USER so that Oracle runs the code with the privileges of the invoker - not the developer (invoker rights procedures). Presto! Without code reviews and / or debugging you will have hardened your PL/SQL web application! In this free tutorial from SkillBuilders Director of Oracle Database Services, Oracle Certified Master John Watson will demonstrate the development of a simple PL/SQL web application, demonstrate SQL injection and how to prevent it with this new feature.

Oracle 12c PL/SQL Security Enhancements - Session 2 of 8- Tutorial Agenda
 
04:11
What's in the SkillBuilders Oracle 12c PL/SQL Security New Features tutorial. John Watson: What I want to talk about today is some security issues with 11g PL/SQL and then moving on to Oracle Database 12c. [see how they've been addressed] In general previous releases of the database have had real problems with security particularly with PL/SQL. This does cause a bit of confusion out there when you read third party assessments contrasting Oracle security with say SQL server and so on. Some people will say that Oracle security is rubbish. Other people will say it's fantastic. What causes that paradox? It's because you can secure your database, but you have to do it. Out of the box the database is stuffed full of marvelous facilities - the developer's marvelous facilities for users - but many of them are potentially highly dangerous. So make no mistake. Oracle database can and should be totally secure, but if your DBAs and your programmers don't make it secure it may be wide open to abuse, wide open to hackers. This has always been a problem. With later releases 11 and now 12, the situation is improving. There are more and more things that one can do declaratively, more techniques for tightening up those wonderfully powerful facilities that can be open to abuse. So what I'm going to go through is spend some time with 11g. We have to. We have to understand what some of the problems are that are being addressed. Also, of course, 11g will be available to be useful for several years to come. I'll spend some time in 11g environment looking at some of the major issues in the PL/SQL environment. Then we will move on to 12c and see some of the new facilities and see how they tighten up the security issues that we see with 11g. If possible - I don't know if this will come true or not - I'll maybe have quick look at network access control list I completely re-implemented in 12c and maybe talk a bit about the advanced security option as well as that has changed somewhat too. That's the agenda I intend to follow. Beginning with 11g, we'll go through what are the definer's rights, what are invoker's rights for code, the relationship between roles and PL/SQL. These issues, definer's rights, invoker's rights and roles is potentially very useful but cause a lot of confusion. I remember when I installed PL/SQL, it first came when it was first introduced in version 7 many, many years ago I found this mind bogglingly confusing. Invoker's rights came in a couple of releases later and then died. That added to the confusion because invoker's rights attempted to fix the problem caused by definer's rights. Roles have always been confusing in the PL/SQL 11g environment. We then move on to the 12c techniques. It's a whole new privilege - inherit privileges or inherit any privileges. That tightens up some of the problems with both views and with PL/SQL. They're very nice facility indeed. We can now grow up roles to procedures, so the confusion of roles in PL/SQL, that is not removed, but we can use roles in a much more [03:31 inaudible] fashion with PL/SQL in 12c. Also, closer [03:35 inaudible], that's the concept of the bequeath view. Just as PL/SQL stored procedures they execute definer's rights to invoker's rights with the privileges of the person who owns the PL/SQL or with the privileges of the person who invokes the PL/SQL. It's the same with views. Historically views are always executed with the privileges of the owner. Now, to a certain extent we can have what I might always call an invoker's rights view. Then if we have time, a couple of other things as well.

PL/SQL Tutorial Part - 1

In Oracle database management, PL/SQL is a procedural language extension to Structured Query Language (SQL). The purpose of PL/SQL is to combine database language and procedural programming language.The basic difference between two languages is that SQL executes the single query at a time whereas, Pl/SQL executes the block of code at once. SQL is a Structured Query Language whereas, PL/SQL is a Procedural Language/ Structured Query Language.PL/SQL is an extension of Structured Query Language (SQL) that is used in Oracle. Unlike SQL, PL/SQL allows the programmer to write code in a procedural format. ... It combines the data manipulation power of SQL with the processing power of procedural language to create super powerful SQL queries.The PL/SQL is a procedural language that is an extension to the Oracle SQL or relational databases. ... In order to learn PL/SQL one should have basic knowledge of programming languages specifically be good on managing the SQL platform. Learning PL/SQL at your own pace might sometimes become complicated.The main feature of SQL (non procedural) is also a drawback of SQL: one cannot use control statements (decision-making or iterative control) if only SQL is to be used. PL/SQL is basically a procedural language, which provides functionality of decision making, iteration and many more features like other procedural programming languages. A PL/SQL program unit is one of the following: PL/SQL anonymous block, procedure, function, package specification, package body, trigger, type specification, type body, library. Program units are the PL/SQL source code that is compiled, developed and ultimately executed on the database

Chuck Tuffli: Running Linux applications on FreeBSD -- BSDCan 2018
 
01:00:41
While FreeBSD has been able to run Linux binaries for many years, the large ecosystem of Docker images leads to some interesting use cases for FreeBSD developers and users. This talk will review how the various kernel modules execute Linux binaries, several ways to use this functionality, and the work in progress to improve the Linux syscall compatibility. FreeBSD has been able to run Linux binaries since 1995, not through virtualization or emulation, but by understanding the Linux executable format and providing a Linux specific system call table. Originally, this was for the noble goal of playing the video game, Doom. Over time, many Linux applications and libraries have been packaged and made available through the FreeBSD Ports Collection. But because FreeBSD tools do not understand Linux package dependencies, this process is manual and time consuming. Docker has popularized the use of Linux Containers, similar to FreeBSD's jails, but more importantly, has lead to publishing a wide variety of both Linux system and application images. These images allow FreeBSD users to download a variety of Linux system images and use their native tools to provide applications not available through the Ports Collection. This started as a simple quest to build Linux device drivers and applications on my FreeBSD system, but the journey has lead to an understanding of the inner workings of the Linux Binary Compatibility layer. It started by running applications from ports, progressed to chroot'd Docker image based environments, and has end up in Docker image based jails. The talk will cover the technology behind this capability as well as examples of using this in practice. Additionally, it will cover some of my work-in-progress to enhance the Linux support for network sockets, capabilities (a.k.a. privileges), mremap, and others. http://www.bsdcan.org/2018/schedule/events/976.en.html

This is the first in a series of three recorded webcasts in the Oracle Data Integrator 12c: Getting Started series. The tutorials are located at https://apex.oracle.com/pls/apex/f?p=44785:24:0::::P24_CONTENT_ID,P24_PREV_PAGE:7952,1. Repositories are schemas and tables in a database that hold information about ODI Designs, Topologies, and Security. There is a one-to-many relationship between Master and Work repositories. The repository schemas and tables can be created either manually using ODI Studio or automatically using Repository Creation Utility (RCU). RCU is the preferred method of maintaining the repositories. The database storing the repository can be Oracle Database 12c or several other supported databases. This recording will walk you through the steps that are needed to create and connect to the Oracle Data Integrator (ODI) Master Repository and the ODI Work Repository using Repository Creation Utility (RCU) and ODI Studio.
