asdfuzz 0.0.0

Web application fuzzer that automatically detects and fuzzes data in HTTP requests

asdfuzz

Web application fuzzer that automatically detects and fuzzes the following data in HTTP requests:

• URL directories
• URL parameters
• Cookies
• Form data
• JSON data

Example

The starting point of fuzzing can be a raw HTTP request or OWASP ZAP message export. Every individual field will be fuzzed in a separate section and the results are shown on screen. The performed requests and received responses are stored by default in a folder called asdfuzz_output/ for later reference. To skip a section while the fuzzer is already running, press [control]+[spacebar].

Individual fields in JSON data will be fuzzed recursively. If base64-urlencoded JSON is present in parameters or cookies, this data will be fuzzed recursively as well.

Usage

Usage: python -m asdfuzz [OPTIONS]

Options:
  --filename PATH                 File containing a single HTTP request to
                                  fuzz.

                                  parameter is empty. In the wordlist, use
                                  template <original> to refer dynamically to
