Fuzdir
Web path fuzzer
Installing
Run the following command to install with pip:
$ pip3 install fuzdir Run the following commands to manually install:
$ git clone https://github.com/n3v4/fuzdir.git fuzdir
$ cd fuzdir
$ python3 setup.py installUsage
You can start the process of fuzzing files and directories with the following command:

--ignore-retry-fail ignore failed attempts to connect to server and continue fuzzing
--throttling [SECONDS]
delay time in seconds (float) between requests sending, if the throttling value is not specified, it will automatically adjust during fuzzing
--proxy URL HTTP or SOCKS5 proxy
usage format:
[http|socks5]://user:pass@host:port
request settings:
--user-agent USER AGENT
custom user agent, by default setting random user agent
-c COOKIE, --cookie COOKIE
-H HEADER, --header HEADER
pass custom header(s)
--allow-redirect allow follow up to redirection
logging settings:
-v, --verbose verbose logging
reports settings:
--report CONFIG reports on responses
available types:
plain a plain text reporting
json a reporting in JSON
usage format:
<type>[:components]=<path>
available components:
json:
body a response body
length a response content length
headers a response headers
code a response status code
examples:
plain=/tmp/report.txt a plain text reporting about the found status code, content length and path
json=/tmp/report.json a reporting in JSON about the found status code, content length and path
json:code,body=/tmp/report.json a reporting in JSON about the found status code, body and path
filter:
-x CONDITIONS conditions for responses matching
available conditions:
code filter by status code
length filter by content length
grep filter by regex in response headers or / and body
usage format:
[ignore:]<condition>[:<area>]=<args>[;]
examples:
code=200,500 match responses with 200 or 500 status code
ignore:code=404 match responses exclude with 404 status code
length=0-1337,7331 match responses with content length between 0 and 1337 or equals 7331
grep='regex' match responses with 'regex' in headers or body
grep:body='regex' match responses with 'regex' in body
code=200;length=0-1337 match responses with 200 status code and content length between 0 and 1337
examples:
fuzdir -u https://example.com -W wordlist.txt
fuzdir -u https://example.com -w index,robots -e html,txt
fuzdir -u https://example.com -W wordlist.txt -e html,js,php -x code=200
fuzdir -u https://example.com -W wordlist.txt -x code=200;ignore:grep:headers='Auth'Extensions
Extensions can be specified as .ext or ext, or as a formatted string %.ext. For example, if wordlist contains only
index, and the extensions php, .html, %.txt, the following path will be sent to the server:
/index
/index.php
/index.html
/index.txt
Throttling
Throttling allows you to adjust the frequency of sending packets to the server. To do this, you can explicitly pass the
number of seconds that must elapse before sending the next packet to the server. For example, if the argument
--throttling 2.5 is passed to fuzdir, then 1 packet will be sent to the server every 2.5 seconds.
When throttling value isn't specified, fuzdir adjusts the throttling value during fuzzing, tracking the response time from the server.
By default, throttling completely disabled, similar --throttling 0.
Custom header(s)
You can pass one or more custom headers with -H or --header. For example, if you pass -H Platform:web and
-H "Token: reWfBt1fnbgjEhA6wfs+Uw==" the following HTTP-request will be sent to the server:
GET /path HTTP/1.1
Host: www.example.com
...
Platform: web
Token: reWfBt1fnbgjEhA6wfs+Uw==
...
Retry settings
You can specify a list of HTTP status codes with --retry-status-list, for which fuzdir should resend the request to
the server, the default value is 502, 503, 504.
The number of attempts can be adjusted using --retry from 0 to 5 inclusive, by default 3 attempts.
By default, if all attempts were fail, fuzzing will be interrupted and the program will exit. To avoid this, you can use
--ignore-retry-fail.
Report
You can write a fuzzing results to file with --report key.
Usage format <type>[:components]=<path>
typereport type,componentslist of components that should be included in the report,pathpath to file.
Currently it supports the following components:
bodya response body,lengtha response content length,headersa response headers,codea response status code.
Currently it supports the following report types:
| Type | Default Components | Supported Components | Examples |
|---|---|---|---|
| plain | code, length | no | --report plain=/tmp/report.txt a plain text reporting about the found status code, content length and path |
| json | code, length | body, length, headers, code | --report json=/tmp/report.txt a reporting in JSON about the found status code, content length and path--report json:code,body=/tmp/report.json a reporting in JSON about the found status code, body and path |
Conditions
Conditions is a system for filtering HTTP responses during fuzzing.
Usage format [ignore]:<condition>:[<area>]=<args>[;]
ignorecondition inverting,conditioncondition name,areasearch area (only grep supported),argscondition arguments.
Currently it supports the following conditions:
| Condition | Area | Args | Examples |
|---|---|---|---|
| code | no | list of status codes (or ranges) separated by comma | -x code=200,500-503 match responses with 200, 500, 501, 502, or 503 status code |
| length | no | list of lengths (or ranges) separated by comma | -x length=0-1337,7331 match responses with content length between 0 and 1337 or equals 7331 |
| grep | headers, body | regex | -x grep=token match responses which contains 'token' in headers or body -x grep:body=token match responses which contains 'token' in body |
You can use multiple conditions, separating them with a semicolon, for example: -x code=200;length=0-1337
