WebmapJS crawler is based on phantomjs. The architecture is simple:
- it runs javascript code inside phantomjs and hook javascript function which loads a URL and extracts links, forms and ajax
- The phantomjs binary is run as a web server to accept the post parameters.
- The javascript code outputs JSON encoded messages to http output with the links, forms and ajax
For the user the requirement is very simple: "Install phantomjs version > 2.0". This
is solved with apt install phantomjs in Debian based distributions.
phantomjs --ssl-protocol=any --ignore-ssl-errors=true phantomjs_spider.js 9000
You can use Burp Suite to send HTTP data to detect the existing links on the current page. It can detect HTML link form and Ajax.
For examples
{
"url":"http://testphp.vulnweb.com/AJAX/index.php",
"data":"",
"method":"GET",
"headers":{
"User-Agent":"Mozilla/5.0 (Windows NT 6.1; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/78.0.3904.108 Safari/537.36"
},
"js_viewport_width":1024,
"js_viewport_height":768,
"load_images":false,
"request_timeout":20,
"followPreRedirections":false
