Making Vulnerable Web-Applications: XXS, RCE, SQL Injection and Stored XSS ( + Buffer Overflow)

In this post I will write some simple vulnerable web applications in python3 and will show how to attack them. This is all for educational purposes and for complete beginners. So please don’t be too hard on me. 😉

Vulnerability Examples

As a first step I will create a basic web-application using twisted python web server (you can learn more about it in “Making simple Nmap SPA web GUI with Apache, AngularJS and Python Twisted“).

VB-Trend 2018 Splunk Conference

Today I attended VB-Trend 2018 Splunk conference organized by system integrator VolgaBlob.

VB-Trend 2018

Video fragments from the event:

Comparing to “Splunk Discovery Day“, the conference was much smaller (less than 100 people), focused on technical aspects, Information Security and informal communication. And I need to say that there really was a lot of talks with colleagues from different companies, not only about Splunk, but also about Vulnerability Management, Application Security and Container Security.

Making CVE-1999-0016 (landc) vulnerability detection script for Windows NT

The fair question is why in 2018 someone might want to deal with Windows NT and vulnerabilities in it. Now Windows NT is a great analogue of DVWA (Damn Vulnerable Web Application), but for operating systems. There are a lot of well-described vulnerabilities with ready-made exploits. A great tool for practising.

Making CVE-1999-0016 (landc) vulnerability detection script for Windows NT

Well, despite the fact that this operating system is not supported since 2004, it can be used in some weird legacy systems. 😉

Adding custom NASL plugins to Tenable Nessus

Making custom NASL scripts (plugins) for Nessus is a pretty complicated process. Basically, NASL (Nessus Attack Scripting Language) is an internal instrument of Tenable and it seem that they are not really interested in sharing it with the community. The only publicly available official documentation, NASL Reference Guide and NASL2 reference manual, was written at least 13 years ago. Certainly many things changed since then in the actual product.

Adding custom NASL plugins to Tenable Nessus

However, it’s still possible to add custom NASL scripts into the plugin set of your Nessus server. Let’s see how to do it. Everything was tested in the latest Nessus 8.
