Video Tutorial: Introduction to custom exploits for buffer overflows (local privilege escalation)

Summary: Video demonstration of discovering a buffer overflow vulnerability in a SUID-root program, determining attributes of the bof, and writing a custom exploit for local privilege escalation on Ubuntu 12.04 by webpwnized ( @webpwnized [https://twitter.com/webpwnized]). While modern operating systems have long been patched against exploits which use direct addressing to exploit buffer overflows, it can be interesting to look at the creation of a custom exploit in order to better understand t

Video: Pen Testing HTML 5 Web Storage

Recorded at the 2012 AIDE conference, this video covers a presentation given by Jeremy Druin; a professional web application and network pen-tester. The topic is pen-testing html5 web storage which is a client-side storage technology available in html5-aware browsers. Web storage is discussed from two perspectives: altering your own web storage and altering the web storage of a remote user. Additionally JSON injection is reviewed to show how cross site scripts can be injected in unconventional

Tutorial: Using web command injection vulnerability to gain administrative shell on Windows web server

In this video, a Windows web server is hosting Mutillidae web application which contains a command injection vulnerability. Using command injection to exploit the Mutillidae web application, we gain a root shell (Administrative Windows cmd shell). The server is fully patched with anti-virus running and a firewall blocking port 23. Additionally the telnet service is disabled. With the command injection vulnerability, this video demonstrates how misconfiguring web services can have serious conseq

Video: Introduction to basic host and service discovery scanning

During the early portion of the scanning phase of pen testing, locating active hosts and identifying the services on open ports is critical in order to determine exposed systems. The video was recorded at the May ISSA Kentuckiana monthly workshop in Louisville and covers basic host discovery scanning. Port scanning and service discovery are covered as well as reporting results. Some of the tools used are nmap, xprobe2, hping3, tcpdump and amap. The speaker is Jeremy Druin (@webpwnized) and was

Tutorial: How to scan exploit Metasploitable-2 using Metasploit, Nexpose, nessus, Nmap, and John-the-Ripper

This video tutorial covers exploiting Metasploitable-2 to get a root shell and eventually a terminal via a valid "sudo-able" login over SSH. Two machines; a test host (Backtrack 5-R2) and a target host (Metasploitable-2) are set up on a VirtualBox host-only network. With this lab network set up, the demonstration walks through a practice pen-test using the phases of recon, scanning, exploitation, post-exploitation, and maintaining access. (Covering tracks and reporting are not covered. Recon is

Tutorial: Using SQL injection to generate cross site scripts

This video discusses a somewhat advanced SQL injection technique in which the SQL injection is not the primary attack. The SQL injection is used to generate cross site scripting. This is useful when cross site scripts cannot be injected into a webpage from a client because web application firewalls or other scanners are in place. When an SQL injection can be snuck past the WAF, it is possible to have the SQL injection generate the Cross Site Script dynamically.

Tutorial: Basics of launching exploits from Metasploit Community Edition

This video covers the basics of launching exploits from Metasploit Community Edition. The exploits were discovered in a previous step both with Nexpose and Nessus. In the case of Nessus the results were exported as a .Nessus file then imported into Metasploit Community Edition. This video picks up right after the vulnerabilities are discovered and imported.
