Allows debugging of vulnerabilities identified by Arachni in Rack-based web applications (Rails, Sinatra, etc.) by running user specified code upon issue reproduction.
The process goes something like this:
- Install
arachni-debug-rackin web application.- Set desired callback.
- IRB
- Pry
- Remote as well.
- Better errors -- pending.
- External Ruby scripts.
- Set desired callback.
- Run Arachni scan.
- Run
arachni_reproducewith the scan report and specify desired issue.- Replays issue.
- Triggers server-side callback.
- DEBUG: The callback runs under the vulnerable state of web application, thus allowing for the issue to be debugged.
Still in alpha phase, may break compatibility (or altogether) without warning.
Add the following to your web application's Gemfile:
gem 'arachni-debug-rack', github: 'Arachni/arachni-debug-rack'Then run bundle install.
Setup the middleware:
require 'arachni/debug/rack'
use Arachni::Debug::Rack::Middleware,
# Only track execution of code in files under this directory and its children.
# You probably want to set this to your application's root directory.
scope: __dir__, # Optional
# Mandatory callback configuration, needs at least a name.
callback: {
# Launch 'irb' in the terminal of the web application.
name: 'irb'
# Launch 'pry' in the terminal of the web application.
# You need to install 'pry' yourself.
# name: 'pry'
# Launch a 'pry' server, accessible using 'pry-remote'.
# You need to install 'pry-remote' yourself.
# name: 'callbacks/pry_remote.rb',
# options: { # Optional
# host: '127.0.0.2', # Optional
# port: 9999 # Optional
# }
# Load an external script to run under the middleware context, with
# access to all relevant trace points and bindings.
# name: '/path/to/external/script.rb',
# You can also pass options to your script, accessible via the
# `options` variable.
# options: { # Optional
# random: 'option' # Optional
# }
}You can try these instructions with the provided example Sinatra application:
# We could just use IRB for these examples, but 'pry' will really drive this home.
gem install pry
bundle exec ruby examples/server.rb -o 0.0.0.0
This project is meant to be used to debug vulnerabilities identified by Arachni,
but the server-side callbacks can be triggered by any request so long as it sets
the X-Arachni-Issue-Digest header.
That X-Arachni-Issue-Digest header is meant to be a numeric checksum used to
uniquely identify issues logged by Arachni.
For example:
$ curl http://127.0.0.2:4567/?myparam=myval -H X-Arachni-Issue-Digest:12345
<a href="/xss?a=b">XSS</a>
And on the server side:
127.0.0.1 - - [16/Apr/2016:23:30:16 +0300] "GET /?myparam=myval HTTP/1.1" 200 31 0.0116

[1] pry(#<Sinatra::Application>)> __method__
=> :"GET /"
[2] pry(#<Sinatra::Application>)> params
=> {"myparam"=>"myval"}
[3] pry(#<Sinatra::Application>)>
As you can see, the Pry console was launched and we were able to do some pretty cool stuff with it.
When used with Arachni it is possible to load scan reports and specify issues to debug.
For this we'll need to use one of the nightly packages, just extract the archive and switch to the package directory.
Scan the web application and get your hands on the resulting AFR report, for example:
./bin/arachni http://127.0.0.2:4567/ --checks xss --browser-cluster-pool-size=0 --report-save-path=report.afr
report.afr is the file we want.
Copy the Digest of the issue you'd like to debug, which you can find towards the
top of each issue printout:
[+] [1] Cross-Site Scripting (XSS) (Trusted)
[~] ~~~~~~~~~~~~~~~~~~~~
[~] Digest: 2593139878
[~] Severity: High
In this case we only have one issue, with a digest of 2593139878.
This information is included in all report formats.
Pass the report and the issue digest to arachni_reproduce, like so:
./bin/arachni_reproduce report.afr 2593139878
You should then see something like:

info the state of the web application at different stages while processing our request.

A ha!
The response body clearly includes the parameter value unescaped, which is why the web application is vulnerable.
This is a helper method, allowing us to filter trace points based on the request index,
in case we've run arachni_reproduce multiple times, for example:

Raw data behind list_trace_points_for_request_id.
This is a helper method, allowing us to filter trace points based on the value
of the X-Arachni-Issue-Digest request header, in case we're run arachni_reproduce
multiple times, for example:
