DESCRIPTION:

Ronin Exploits is a Ruby library for Ronin that provides exploitation and payload crafting functionality.

Ronin is a Ruby platform for exploit development and security research. Ronin allows for the rapid development and distribution of code, exploits or payloads over many common Source-Code-Management (SCM) systems.

Ruby

Ronin's Ruby environment allows security researchers to leverage Ruby with ease. The Ruby environment contains a multitude of convenience methods for working with data in Ruby, a Ruby Object Database, a customized Ruby Console and an extendable command-line interface.

Extend

Ronin's more specialized features are provided by additional Ronin libraries, which users can choose to install. These libraries can allow one to write and run Exploits and Payloads, scan for PHP vulnerabilities, perform Google Dorks or run 3rd party scanners.

Publish

Ronin allows users to publish and share code, exploits, payloads or other data via Overlays. Overlays are directories of code and data that can be hosted on any SVN, Hg, Git or Rsync server. Ronin makes it easy to create, install or update Overlays.

FEATURES:

• Ability to define Payloads based on:
  • Contributing authors.
  • Behaviors they control.
  • Helpers they use.
• Ability to define Payload Encoders:
  • Architectures they target.
  • OSes they target.
• Ability to define Exploits based on:
  • Whether they are local or remote.
  • Protocol they use.
  • Contributing authors.
  • Behaviors they control.
  • Disclosure status.
  • Level of weaponization.
  • Architectures they target.
  • OSes they target.
  • Products they target.
  • Helpers they use.
• Provides a simple three phase process of building, verifying and deploying Exploits and Payloads.
• Allows adding arbitrary target data to the targets of Exploits.
• Allows combining Payloads with Exploits.
• Allows using a raw-payload with an Exploit.
• Allows the addition of multiple Payload Encoders to an Exploit.
• Allows chaining multiple Payloads together.
• Provides a multitude of exploit and payload generators which can create customized skeleton Ruby Exploits and Payloads.

SYNOPSIS:

Generate a skeleton exploit, with some custom information:

$ ronin-gen exploit exploit.rb --name Example \
                               --controls command_exec \
               --status proven \
               --authors Postmodern \
               --description "This is an example."

• To generate other types of exploits, you can specify +local_exploit+, +remote_exploit+, +remote_tcp_exploit+, +remote_udp_exploit+, +ftp_exploit+, +http_exploit+ or +web_exploit+, instead of simply +exploit+.

Generate a skeleton payload, with some custom information:

$ ronin-gen payload payload.rb --name Example \
                               --controls file_read file_write \
               --authors Postmodern \
               --description "This is an example."

• To generate other types of payloads, you can specify +binary_payload+, +shellcode+ or +nops+, instead of simply +payload+.

List available payloads:

$ ronin-payloads

Print information about a payload:

$ ronin-payloads -n NAME -v

Build and output a payload:

$ ronin-payload NAME

Build and output a raw unescaped payload:

$ ronin-payload NAME --raw

Load a payload from a file, then build and output it:

$ ronin-payload -f FILE

List available exploits:

$ ronin-exploits

Print information about an exploit:

$ ronin-exploits -n NAME -v

Build and deploy an exploit:

$ ronin-exploit -n NAME --host example.com --port 9999

Load an exploit from a file, then build and deploy it:

$ ronin-exploit -f FILE --host example.com --port 9999

Build and deploy an exploit, with a payload:

$ ronin-exploit -n NAME --host example.com --port 9999 -P PAYLOAD_NAME

Build and deploy an exploit, with a raw payload:

$ ronin-exploit -n NAME --host example.com --port 9999 \
                --raw-payload \
        `echo -en "\x66\x31\xc0\xfe\xc0\xb3\xff\xcd\x80"`

EXAMPLES:

Define a shellcode payload:

ronin_shellcode do
  #
  # Cacheable data.
  #
  cache do
    self.name = 'test'
    self.version = '0.5'
    self.description = %{This is an example shellcode payload.}

    author(:name => 'Postmodern', :organization => 'SophSec')

    self.arch :i686
    self.os :name => 'Linux'
  end

  #
  # Configurable parameters.
  #
  parameter :exit_status,
            :default => 0,
            :description => 'Exit status of shellcode'

  #
  # Builds the assembly payload, which will call the SYS_EXIT
  # syscall with the exit_status of the shellcode.
  #
  def build
    @payload = "\x66\x31\xc0\xfe\xc0"

    unless @exit_status == 0
      @payload << "\xb3#{@exit_status.chr}"
    else
      @payload << "\x66\x31\xdb"
    end

    @payload << "\xcd\x80"
    return @payload
  end
end

Define a payload encoder:

ronin_payload_encoder do
  #
  # Cacheable data.
  #
  cache do
    self.name = 'base64_encode'
    self.description = %{Example base64 payload encoder}

    self.arch :i686
    self.os :name => 'Linux'
  end

  #
  # Base64 encodes the specified _data_.
  #
  def encode(data)
    return data.to_s.base64_encode
  end
end

Define a remote TCP exploit:

ronin_remote_tcp_exploit do
  helper :buffer_overflow

  #
  # Cacheable data.
  #
  cache do
    self.name = 'test'
    self.description = %{This is an example exploit.}

    self.status = :potential
    self.disclosure = [:in_wild, :public]

    author(:name => 'Postmodern', :organization => 'SophSec')

    controlling :code_exec

    targeting do |target|
      target.arch :i686
      target.os :name => 'Linux'
      target.product :name => 'ExampleWare', :version => '2.4.7b'
    end
  end

  #
  # Builds the exploit.
  #
  def build
    @buffer = "USER #{build_buffer}\n"
  end

  #
  # Deploys the built exploit.
  #
  def deploy
    tcp_send @buffer
  end
end
