  • Oracle with Metasploit
    Oracle Penetration Testing Using the Metasploit Framework Chris Gates & Mario Ceballos Metasploit Project Abstract 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 whitepaper we will 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. The modules are currently only supported under Linux and OSX. Oracle Penetration Testing Methodology Locate a system running Oracle. Determine Oracle Version. Determine Oracle SID. Guess/Bruteforce USERNAME/PASS. Privilege Escalation via SQL Injection. Manipulate Data/Post Exploitation. Cover Tracks. Locating an Oracle System You will typically find most Oracle installations by performing port scanning in the target netblock. The Oracle listener default port is 1521 but can listen on an port generally in the 1521-1540 range. You can also discover oracle instances by scanning other common Oracle ports. Review http://www.red- database-security.com/whitepaper/oracle_default_ports.html for common Oracle ports. Generally running a service scan will NOT give you the Oracle TNS Listener version but updated fingerprints for new versions of Nmap may yield versions in some situations.

  • Metasploit Pro User Guide
    4.11 USER GUIDE Getting Started First things first. If you haven't installed Metasploit yet, check out this these instructions if you're a commercial user. Otherwise, if you already have Metasploit installed, congratulations! You've come to the right place to get started. What's Metasploit? Metasploit is a penetration testing platform that enables you to find, exploit, and validate vulnerabilities. The platform includes the Metasploit Framework and its commercial counterparts: Metasploit Pro, Express, Community, and Nexpose Ultimate. Metasploit Framework The Metasploit Framework is the foundation on which the commercial products are built. It is an open source project that provides the infrastructure, content, and tools to perform penetration tests and extensive security auditing. Thanks to the open source community and Rapid7's own hard working content team, new modules are added on a regular basis, which means that the latest exploit is available to you as soon as it's published. There are quite a few resources available online to help you learn how to use the Metasploit Framework; however, we highly recommend that you take a look at the Metasploit Framework Wiki, which is maintained by Rapid7's content team, to ensure that you have the most up to date information available. You can also use the sidebar navigation on the left to view the documentation that is available on this site; just click on the Metasploit Framework topic or search for the topic you want. Either way, if you are unable to find what you need, let us know, and we will add it to the documentation back log.

    ANEX: AUTOMATED NETWORK EXPLOITATION THROUGH PENETRATION TESTING A Thesis presented to the Faculty of California Polytechnic State University, San Luis Obispo In Partial Fulfillment of the Requirements for the Degree Master of Science in Computer Science by Eric Francis Dazet June 2016 c 2016 Eric Francis Dazet ALL RIGHTS RESERVED ii COMMITTEE MEMBERSHIP TITLE: ANEX: Automated Network Exploitation through Penetration Testing AUTHOR: Eric Francis Dazet DATE SUBMITTED: June 2016 COMMITTEE CHAIR: Bruce Edward DeBruhl II, Ph.D. Assistant Professor of Computer Science COMMITTEE MEMBER: Zachary J. Peterson, Ph.D. Associate Professor of Computer Science COMMITTEE MEMBER: Phillip Nico, Ph.D. Professor of Computer Science iii ABSTRACT ANEX: Automated Network Exploitation through Penetration Testing Eric Francis Dazet Cyber attacks are a growing concern in our modern world, making security evalua- tion a critical venture. Penetration testing, the process of attempting to compromise a computer network with controlled tests, is a proven method of evaluating a sys- tem's security measures. However, penetration tests, and preventive security analysis in general, require considerable investments in money, time, and labor, which can cause them to be overlooked. Alternatively, automated penetration testing programs are used to conduct a security evaluation with less user effort, lower cost, and in a shorter period of time than manual penetration tests. The trade-off is that automated penetration testing tools are not as effective as manual tests. They are not as flexible as manual testing, cannot discover every vulnerability, and can lead to a false sense of security. The development of better automated tools can help organizations quickly and frequently know the state of their security measures and can help improve the manual penetration testing process by accelerating repetitive tasks without sacrificing results.
