This script can automatically retrieve OAuth2 grants (JSON Web Tokens (JWT)) from an Active Directory Federation Services (ADFS) server. These tokens subsequently can be automatically copied to the clipboard, or used in other tools. Very handy for automating retrieval of short-lived tokens.
The script can also 'brute-force' API endpoints, when passed a list of possible URLs. This might come in handy if you want to 'prefeed' the API endpoints that need authentication to your favourite proxy tool, e.g. Burp Suite or OWASP ZAP. By default it does a GET, POST, PUT and DELETE, with static values.
pip install {jwt,requests,pyclipboard}
Grab a token from an endpoint (automatically logs in, receives a login cookie, requests an authorization token, and converts that to an authorization token for the requested application):
./apiborker.py --adfs-login="https://my.login.server/authorize" --adfs-code="https://my.login.server/authorize" --adfs-token="https://my.login.server/authorize" --resource="https://api.endpoint/authorize" --client-id=X-Y-Z --redirect-uri="X-Y-X" --username="USERNAME" --password="PASSWORD"
Re-use the login cookie (which usually has a longer expiry than codes), grab a token, and test some API calls contained in endpoints.txt:
./apiborker.py --cookie=COOKIE --adfs-code="https://my.login.server/authorize" --adfs-token="https://my.login.server/authorize" --resource="https://api.endpoint/authorize" --client-id=X-Y-Z --redirect-uri="X-Y-X" --username="USERNAME" --password="PASSWORD" --inputfile=endpoints.txt"
