By: Paulino Calderon

Overview of this book

This is the second edition of ‘Nmap 6: Network Exploration and Security Auditing Cookbook’. A book aimed for anyone who wants to master Nmap and its scripting engine through practical tasks for system administrators and penetration testers. Besides introducing the most powerful features of Nmap and related tools, common security auditing tasks for local and remote networks, web applications, databases, mail servers, Microsoft Windows machines and even ICS SCADA systems are explained step by step with exact commands and argument explanations. The book starts with the basic usage of Nmap and related tools like Ncat, Ncrack, Ndiff and Zenmap. The Nmap Scripting Engine is thoroughly covered through security checks used commonly in real-life scenarios applied for different types of systems. New chapters for Microsoft Windows and ICS SCADA systems were added and every recipe was revised. This edition reflects the latest updates and hottest additions to the Nmap project to date. The book will also introduce you to Lua programming and NSE script development allowing you to extend further the power of Nmap.

Making HTTP requests to identify vulnerable supermicro IPMI/BMC controllers


The Nmap Scripting Engine has a library to handle requests and other common functions of an HTTP client. With the http NSE library, NSE developers can accomplish many tasks, from information gathering to vulnerability exploitation of web applications.

This recipe will show you how to use the http NSE library to send an HTTP request to identify vulnerable supermicro IPMI/BMC controllers.

How to do it...

Some supermicro IPMI/BMC controllers allow unauthenticated access to a configuration file (/PSBlock) that stores plain text administrative credentials. Let's write a simple NSE script to detect these vulnerable controllers.

For now, let's ignore the documentation tags and keep it simple:

  1. Create the file supermicro-psblock.nse and start by filling up the NSE script basic information fields:
   description = [[

   containing plain-text user credentials in vulnerable...
