A couple of years ago I was inspired by @fmavituna's work on XSS Shell and decided to write a new extended version (XSS-Shell-NG) using a PHP and a MySQL backend rather than the ASP/Access combination of the original. I never released the tool publicly, as my main aim of making XSS Shell easier to use was never really accomplished; it still required a significant amount of set up to get it working. However, one thing that both tools did well once working was to demonstrate the real business impact of cross-site scripting.
To demonstrate the real business impact of cross site scripting I have developed a completely new tool from the ground up - XSS-Harvest. It is multi-threaded pre-forking web server written in Perl, and requires no dependencies other than a couple of common Perl modules; you do not need a web server or database to use this tool. Before going into the detail, I'll list the high level functionality below:
