Arjun : HTTP Parameter Discovery Suite

Also Read – PFQ : Functional Network Framework for Multi-Core Architectures

Usage

Note: Arjun doesn't work with python < 3.4

Discover parameters

To find GET parameters, you can simply do:

python3 arjun.py -u https://api.example.com/endpoint –get

Similarly, use –post to find POST parameters.

Multi-threading

Arjun uses 2 threads by default but you can tune its performance according to your network connection.

python3 arjun.py -u https://api.example.com/endpoint –get -t 22

Delay between requests

You can delay the request by using the -d option as follows:

python3 arjun.py -u https://api.example.com/endpoint –get -d 2

Including presistent data

Let’s say you have an API key that you need to send with every request, to tell Arjun to do that you can use the –include option as follows:

python3 arjun.py -u https://api.example.com/endpoint –get –include ‘api_key=xxxxx’
OR
python3 arjun.py -u https://api.example.com/endpoint –get –include ‘{“api_key”:”xxxxx”}’

To include multiple parameters, use & to seperate them or pass them as a valid json object.

JSON Output

You can save the result in a JSON format by using the -o as follows:

python3 arjun.py -u https://api.example.com/endpoint –get -o result.json

Adding HTTP Headers

Using the –headers switch will open an interactive prompt where you can paste your headers. Press Ctrl + S to save and Ctrl + X to procced.
