BypassFuzzer - Fuzz 401/403/404 Pages For Bypasses

By: Zion3R — May 13th 2024 at 12:30


The original 403fuzzer.py :)

Fuzz 401/403ing endpoints for bypasses

This tool performs various checks via headers, path normalization, verbs, etc. to attempt to bypass ACL's or URL validation.

It will output the response codes and length for each request, in a nicely organized, color coded way so things are reaable.

I implemented a "Smart Filter" that lets you mute responses that look the same after a certain number of times.

You can now feed it raw HTTP requests that you save to a file from Burp.

Follow me on twitter! @intrudir


Usage

usage: bypassfuzzer.py -h

Specifying a request to test

Best method: Feed it a raw HTTP request from Burp!

Simply paste the request into a file and run the script!
- It will parse and use cookies & headers from the request. - Easiest way to authenticate for your requests

python3 bypassfuzzer.py -r request.txt

Using other flags

Specify a URL

python3 bypassfuzzer.py -u http://example.com/test1/test2/test3/forbidden.html

Specify cookies to use in requests:
some examples:

--cookies "cookie1=blah"
-c "cookie1=blah; cookie2=blah"

Specify a method/verb and body data to send

bypassfuzzer.py -u https://example.com/forbidden -m POST -d "param1=blah&param2=blah2"
bypassfuzzer.py -u https://example.com/forbidden -m PUT -d "param1=blah&param2=blah2"

Specify custom headers to use with every request Maybe you need to add some kind of auth header like Authorization: bearer <token>

Specify -H "header: value" for each additional header you'd like to add:

bypassfuzzer.py -u https://example.com/forbidden -H "Some-Header: blah" -H "Authorization: Bearer 1234567"

Smart filter feature!

Based on response code and length. If it sees a response 8 times or more it will automatically mute it.

Repeats are changeable in the code until I add an option to specify it in flag

NOTE: Can't be used simultaneously with -hc or -hl (yet)

# toggle smart filter on
bypassfuzzer.py -u https://example.com/forbidden --smart

Specify a proxy to use

Useful if you wanna proxy through Burp

bypassfuzzer.py -u https://example.com/forbidden --proxy http://127.0.0.1:8080

Skip sending header payloads or url payloads

# skip sending headers payloads
bypassfuzzer.py -u https://example.com/forbidden -sh
bypassfuzzer.py -u https://example.com/forbidden --skip-headers

# Skip sending path normailization payloads
bypassfuzzer.py -u https://example.com/forbidden -su
bypassfuzzer.py -u https://example.com/forbidden --skip-urls

Hide response code/length

Provide comma delimited lists without spaces. Examples:

# Hide response codes
bypassfuzzer.py -u https://example.com/forbidden -hc 403,404,400  

# Hide response lengths of 638
bypassfuzzer.py -u https://example.com/forbidden -hl 638

TODO

  • [x] Automatically check other methods/verbs for bypass
  • [x] absolute domain attack
  • [ ] Add HTTP/2 support
  • [ ] Looking for ideas. Ping me on twitter! @intrudir

Forbidden-Buster - A Tool Designed To Automate Various Techniques In Order To Bypass HTTP 401 And 403 Response Codes And Gain Access To Unauthorized Areas In The System

By: Zion3R — November 14th 2023 at 11:30


Forbidden Buster is a tool designed to automate various techniques in order to bypass HTTP 401 and 403 response codes and gain access to unauthorized areas in the system. This code is made for security enthusiasts and professionals only. Use it at your own risk.

  • Probes HTTP 401 and 403 response codes to discover potential bypass techniques.
  • Utilizes various methods and headers to test and bypass access controls.
  • Customizable through command-line arguments.

Install requirements

pip3 install -r requirements.txt

Run the script

python3 forbidden_buster.py -u http://example.com

Forbidden Buster accepts the following arguments:

fuzzing (stressful) --include-user-agent Include User-Agent fuzzing (stressful)" dir="auto">
  -h, --help            show this help message and exit
  -u URL, --url URL     Full path to be used
  -m METHOD, --method METHOD
                        Method to be used. Default is GET
  -H HEADER, --header HEADER
                        Add a custom header
  -d DATA, --data DATA  Add data to requset body. JSON is supported with escaping
  -p PROXY, --proxy PROXY
                        Use Proxy
  --rate-limit RATE_LIMIT
                        Rate limit (calls per second)
  --include-unicode     Include Unicode fuzzing (stressful)
  --include-user-agent  Include User-Agent fuzzing (stressful)

Example Usage:

python3 forbidden_buster.py --url "http://example.com/secret" --method POST --header "Authorization: Bearer XXX" --data '{\"key\":\"value\"}' --proxy "http://proxy.example.com" --rate-limit 5 --include-unicode --include-user-agent

Wordlists (IMPORTANT)

Summary:

  • Wordlist is a text file, each line is a path.
  • About extensions, Afuzz replaces the %EXT% keyword with extensions from -e flag.If no flag -e, the default is used.
  • Generate a dictionary based on domain names. Afuzz replaces %subdomain% with host, %rootdomain% with root domain, %sub% with subdomain, and %domain% with domain. And generated according to %ext%

Examples:

  • Normal extensions
index.%EXT%

Passing asp and aspx extensions will generate the following dictionary:

index
index.asp
index.aspx
  • host
%subdomain%.%ext%
%sub%.bak
%domain%.zip
%rootdomain%.zip

How to use

Some examples for how to use Afuzz - those are the most common arguments. If you need all, just use the -h argument.

Simple usage

afuzz -u https://target
afuzz -e php,html,js,json -u https://target
afuzz -e php,html,js -u https://target -d 3

Threads

The thread number (-t | --threads) reflects the number of separated brute force processes. And so the bigger the thread number is, the faster afuzz runs. By default, the number of threads is 10, but you can increase it if you want to speed up the progress.

In spite of that, the speed still depends a lot on the response time of the server. And as a warning, we advise you to keep the threads number not too big because it can cause DoS.

afuzz -e aspx,jsp,php,htm,js,bak,zip,txt,xml -u https://target -t 50

Blacklist

The blacklist.txt and bad_string.txt files in the /db directory are blacklists, which can filter some pages

The blacklist.txt file is the same as dirsearch.

The bad_stirng.txt file is a text file, one per line. The format is position==content. With == as the separator, position has the following options: header, body, regex, title

Language detection

The language.txt is the detection language rule, the format is consistent with bad_string.txt. Development language detection for website usage.
