# 웹 도구 - WFuzz

{{#include ../banners/hacktricks-training.md}}

웹 애플리케이션을 어디서나 FUZZ하는 도구입니다.

> [Wfuzz](https://github.com/xmendez/wfuzz)는 웹 애플리케이션 평가 작업을 용이하게 하기 위해 만들어졌으며, 간단한 개념에 기반합니다: FUZZ 키워드에 대한 모든 참조를 주어진 페이로드의 값으로 대체합니다.

## 설치

Kali에 설치됨

Github: [https://github.com/xmendez/wfuzz](https://github.com/xmendez/wfuzz)
```
pip install wfuzz
```
## 필터링 옵션
```bash
--hs/ss "regex" #Hide/Show
#Simple example, match a string: "Invalid username"
#Regex example: "Invalid *"

--hc/sc CODE #Hide/Show by code in response
--hl/sl NUM #Hide/Show by number of lines in response
--hw/sw NUM #Hide/Show by number of words in response
--hh/sh NUM #Hide/Show by number of chars in response
--hc/sc NUM #Hide/Show by response code
```
## 출력 옵션
```bash
wfuzz -e printers #Prints the available output formats
-f /tmp/output,csv #Saves the output in that location in csv format
```
### 인코더 옵션
```bash
wfuzz -e encoders #Prints the available encoders
#Examples: urlencode, md5, base64, hexlify, uri_hex, doble urlencode
```
인코더를 사용하려면 **"-w"** 또는 **"-z"** 옵션에서 이를 지정해야 합니다.

예시:
```bash
-z file,/path/to/file,md5 #Will use a list inside the file, and will transform each value into its md5 hash before sending it
-w /path/to/file,base64 #Will use a list, and transform to base64
-z list,each-element-here,hexlify #Inline list and to hex before sending values
```
## CheatSheet

### 로그인 폼 브루트포스

#### **POST, 단일 목록, 필터 문자열 (숨기기)**
```bash
wfuzz -c -w users.txt --hs "Login name" -d "name=FUZZ&password=FUZZ&autologin=1&enter=Sign+in" http://zipper.htb/zabbix/index.php
#Here we have filtered by line
```
#### **POST, 2 목록, 필터 코드 (표시)**
```bash
wfuzz.py -c -z file,users.txt -z file,pass.txt --sc 200 -d "name=FUZZ&password=FUZ2Z&autologin=1&enter=Sign+in" http://zipper.htb/zabbix/index.php
#Here we have filtered by code
```
#### **GET, 2 목록, 필터 문자열 (표시), 프록시, 쿠키**
```bash
wfuzz -c -w users.txt -w pass.txt --ss "Welcome " -p 127.0.0.1:8080:HTTP -b "PHPSESSIONID=1234567890abcdef;customcookie=hey" "http://example.com/index.php?username=FUZZ&password=FUZ2Z&action=sign+in"
```
### Bruteforce Directory/RESTful bruteforce

[Arjun 매개변수 단어 목록](https://raw.githubusercontent.com/s0md3v/Arjun/master/arjun/db/params.txt)
```
wfuzz -c -w /tmp/tmp/params.txt --hc 404 https://domain.com/api/FUZZ
```
### 경로 매개변수 BF
```bash
wfuzz -c -w ~/git/Arjun/db/params.txt --hw 11 'http://example.com/path%3BFUZZ=FUZZ'
```
### 헤더 인증

#### **기본, 2 목록, 필터 문자열 (표시), 프록시**
```bash
wfuzz -c -w users.txt -w pass.txt -p 127.0.0.1:8080:HTTP --ss "Welcome" --basic FUZZ:FUZ2Z "http://example.com/index.php"
```
#### **NTLM, 2 목록, 필터 문자열 (표시), 프록시**
```bash
wfuzz -c -w users.txt -w pass.txt -p 127.0.0.1:8080:HTTP --ss "Welcome" --ntlm 'domain\FUZZ:FUZ2Z' "http://example.com/index.php"
```
### 쿠키/헤더 브루트포스 (vhost 브루트)

#### **쿠키, 필터 코드 (표시), 프록시**
```bash
wfuzz -c -w users.txt -p 127.0.0.1:8080:HTTP --ss "Welcome " -H "Cookie:id=1312321&user=FUZZ"  "http://example.com/index.php"
```
#### **User-Agent, 필터 코드 (숨기기), 프록시**
```bash
wfuzz -c -w user-agents.txt -p 127.0.0.1:8080:HTTP --ss "Welcome " -H "User-Agent: FUZZ"  "http://example.com/index.php"
```
#### **호스트**
```bash
wfuzz -c -w /usr/share/wordlists/SecLists/Discovery/DNS/subdomains-
top1million-20000.txt --hc 400,404,403 -H "Host: FUZZ.example.com" -u
http://example.com -t 100
```
### HTTP Verbs (methods) bruteforce

#### **파일 사용**
```bash
wfuzz -c -w methods.txt -p 127.0.0.1:8080:HTTP --sc 200 -X FUZZ "http://example.com/index.php"
```
#### **인라인 목록 사용**
```bash
$ wfuzz -z list,GET-HEAD-POST-TRACE-OPTIONS -X FUZZ http://testphp.vulnweb.com/
```
### 디렉토리 및 파일 브루트포스
```bash
#Filter by whitelisting codes
wfuzz -c -z file,/usr/share/wordlists/dirbuster/directory-list-2.3-medium.txt --sc 200,202,204,301,302,307,403 http://example.com/uploads/FUZZ
