Introduction


HyperText Transfer Protocol (HTTP) is arguably one of the most popular protocols in use today. Web servers have moved from serving static pages to handling complex web applications with user interaction.

This has opened the doors to tainted user input that could change an application's logic to perform unintended actions. Modern web development frameworks allow almost anyone with some knowledge of programming to produce web applications within minutes, but this has also caused an increase of vulnerable applications on the Internet. The number of available HTTP scripts for the Nmap Scripting Engine grew rapidly, and Nmap turned into an invaluable web scanner that helps penetration testers perform a lot of the tedious manual checks in an automated manner. Not only can it be used to find vulnerable web applications or detect faulty configuration settings, but thanks to the new spidering library, Nmap can even crawl web servers, looking for all sorts of interesting information.
