# Forbidden
Bypass 4xx HTTP response status codes and more. Based on PycURL and Python Requests.
Script uses multithreading and is based on brute forcing, and as such, might have false positive results. Script has colored output.
Results will be sorted by HTTP response status code ascending, HTTP response content length descending, and ID ascending.
To manually filter out false positive results, for each unique HTTP response content length, run the provided cURL command and check if the HTTP response results in bypass; if not, simply ignore all the results with the same HTTP response content length.
| Test Description | Test |

| HTTP and HTTPS requests on both, domain name and IP. | base |
| HTTP methods + w/ `Content-Length: 0` HTTP request header. | methods |
| Cross-site tracing (XST) w/ HTTP TRACE and TRACK methods. | methods |

Check the stress testing script [here](https://github.com/ivan-sincek/forbidden/blob/main/src/stresser/stresser.py). Inspired by this [write-up](https://amineaboud.medium.com/story-of-a-weird-vulnerability-i-found-on-facebook-fc0875eb5125).
Extend the scripts to your liking.
Good sources of HTTP headers:
* [developer.mozilla.org/en-US/docs/Web/HTTP/Headers](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)
* [developers.cloudflare.com/fundamentals/reference/http-request-headers](https://developers.cloudflare.com/fundamentals/reference/http-request-headers)
* [udger.com/resources/http-request-headers](https://udger.com/resources/http-request-headers)
* [webconcepts.info/concepts/http-header](https://webconcepts.info/concepts/http-header)
* [webtechsurvey.com/common-response-headers](https://webtechsurvey.com/common-response-headers)
Tested on Kali Linux v2023.4 (64-bit).
Made for educational purposes. I hope it will help!
---
**Remarks:**
* all HTTP request headers, values, URL path bypasses, etc., were validated based on the official documentation or public infosec write-ups,
* by default, `Forbidden` is "locked" to `PycURL` and `Stresser` is "locked" to `Python Requests`,
* Python Requests is up to 3x faster than PycURL, but PycURL is a bit more customizable,
* PycURL might also throw `OSError` if large number of threads is used due to opening too many session cookie files at once,
* by default, only `2xx` and `3xx` HTTP status codes are included in results and shown in the output,
* `length` attribute in results includes only HTTP response body length,
* testing `double headers` is locked to `Python Requests` because PycURL does not support it,
* testing `encodings` is locked to `PycURL` because Python Requests does not support it,
* connection and read timeout is set to `60` seconds,
* beware of `rate limiting` and other similar anti-bot protections, take some time before running the script again on the same domain,
* some web proxies might normalize URLs (e.g., when testing `encodings`), modify HTTP requests, or drop HTTP requests entirely,
* some websites might require a valid or very specific `User-Agent` HTTP request header,
* cross-site tracing (XST) is `no longer` considered to be a vulnerability.
**High priority plans:**
* add the silent option, to not show the console output,
* add the no color option, to not show colors in the console output,
* use brute forcing to validate allowed HTTP methods if HTTP OPTIONS method is not allowed,
* add tests for HTTP cookies, `User-Agent` HTTP request header, CRLF, and Log4j.
**Low priority plans:**
* add option to test custom HTTP header-value pairs for a list of domains/subdomains.

# URL Paths
Inject at the beginning, end, and both, beginning and end of the URL path.
Test using every possible combination of the payload set (default - cluster bomb) or place the same payload into all of the defined payload positions simultaneously (battering ram).
```fundamental
/
//
%09
%20
%23
%2e
%a0
*
.
..
;
.;
..;
/;/
;/../../
;foo=bar;
```

#
##
##random

**
**random
.

..random
?
??
