ffuf 模糊测试工具完整参考
ffuf (Fuzz Faster U Fool) 是最灵活的 Web 模糊测试工具。核心概念:用 FUZZ 关键字标记需要替换的位置。
Phase 1: 目录/文件发现(最常用)
# 基础目录扫描
ffuf -u http://target/FUZZ -w /usr/share/seclists/Discovery/Web-Content/common.txt
# 指定扩展名
ffuf -u http://target/FUZZ -w /usr/share/seclists/Discovery/Web-Content/common.txt \
-e .php,.html,.txt,.bak,.zip
# 递归扫描(发现目录后继续深入)
ffuf -u http://target/FUZZ -w wordlist.txt -recursion -recursion-depth 2
# 大字典深度扫描
ffuf -u http://target/FUZZ -w /usr/share/seclists/Discovery/Web-Content/directory-list-2.3-medium.txt \
-e .php,.asp,.jsp -t 50
字典选择
| 场景 | 推荐字典 |
|---|---|
| 快速扫描 | Discovery/Web-Content/common.txt (4660) |
| 中等扫描 | Discovery/Web-Content/directory-list-2.3-small.txt (87k) |
| 深度扫描 | Discovery/Web-Content/directory-list-2.3-medium.txt (220k) |
| 备份文件 | Discovery/Web-Content/common-and-backup.txt |
| API 路径 | Discovery/Web-Content/api/api-endpoints.txt |
| CTF 常见 | /pentest/AboutSecurity/Dic/Web/CTF/ |
Phase 2: 参数 Fuzz(发现隐藏参数)
# GET 参数发现
ffuf -u 'http://target/page.php?FUZZ=test' \
-w /usr/share/seclists/Discovery/Web-Content/burp-parameter-names.txt \
-fs 4242 # 过滤默认响应大小
# GET 参数值 Fuzz
ffuf -u 'http://target/page.php?id=FUZZ' \
-w /usr/share/seclists/Fuzzing/integers-1-1000.txt
# POST 参数发现
ffuf -u 'http://target/api' -X POST \
-d 'FUZZ=test' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-w /usr/share/seclists/Discovery/Web-Content/burp-parameter-names.txt \
-fs 4242
# JSON 参数 Fuzz
ffuf -u 'http://target/api' -X POST \
-d '{"FUZZ":"test"}' \
-H 'Content-Type: application/json' \
-w /usr/share/seclists/Discovery/Web-Content/burp-parameter-names.txt \
-fs 4242
CTF 专用参数字典:/pentest/AboutSecurity/Dic/Web/CTF/Fuzz_param.txt
Phase 3: 虚拟主机 / 子域名枚举
# 虚拟主机枚举(通过 Host 头)
ffuf -u http://target/ -H 'Host: FUZZ.target.com' \
-w /usr/share/seclists/Discovery/DNS/subdomains-top1million-5000.txt \
-fs 4242 # 过滤默认页面大小
Phase 4: 多位置 Fuzz
ffuf 支持多个 FUZZ 关键字(用不同名称区分):
# 用户名+密码爆破
ffuf -u http://target/login -X POST \
-d 'username=HFUZZ&password=WFUZZ' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-w users.txt:HFUZZ -w passwords.txt:WFUZZ \
-fc 401 # 过滤 401 响应
# 目录+扩展名组合
ffuf -u http://target/W1FUZZ.W2FUZZ \
-w dirs.txt:W1FUZZ -w extensions.txt:W2FUZZ \
-mode clusterbomb # 所有组合(笛卡尔积)
Fuzz 模式
| 模式 | 说明 | 场景 |
|---|---|---|
clusterbomb | 所有组合(默认) | 用户名×密码 |
pitchfork | 一一对应 | 已知配对的凭据 |
sniper | 单字典逐位置 | 单参数多位置 |
Phase 5: 过滤与匹配(关键!)
ffuf 默认显示所有响应,需要过滤噪音:
过滤(排除不想要的)
| 参数 | 作用 | 示例 |
|---|---|---|
-fc | 过滤状态码 | -fc 404,403,500 |
-fs | 过滤响应大小 | -fs 4242 |
-fw | 过滤响应词数 | -fw 12 |
-fl | 过滤响应行数 | -fl 5 |
-fr | 过滤正则匹配 | -fr 'not found' |
-ft | 过滤响应时间 | -ft '>3000'(>3秒) |
匹配(只显示想要的)
| 参数 | 作用 | 示例 |
|---|---|---|
-mc | 匹配状态码 | -mc 200,301,302 |
-ms | 匹配响应大小 | -ms 1234 |
-mw | 匹配响应词数 | -mw 100-500 |
-mr | 匹配正则 | -mr 'flag\{.*\}' |
技巧:先不加过滤跑一次,观察默认响应大小,然后用 -fs 过滤掉。
Phase 6: 常用选项
# 线程数(默认 40,可调高)
-t 100
# 延迟(避免被封,单位秒;0.1 = 100ms)
-p 0.1
# 请求速率限制(每秒请求数)
-rate 50
# 自定义 Cookie
-b 'session=abc123; token=xyz'
# 自定义 Header
-H 'Authorization: Bearer TOKEN'
-H 'X-Forwarded-For: 127.0.0.1'
# 代理
-x http://127.0.0.1:8080
-x socks5://127.0.0.1:1080
# 输出到文件
-o results.json -of json
-o results.csv -of csv
-o results.html -of html
# 自动校准(自动检测过滤基线)
-ac
# 跟随重定向
-r
# 超时(秒)
-timeout 10
# 静默模式(只输出结果)
-s
实战场景速查
| 场景 | 命令 |
|---|---|
| 快速目录扫描 | ffuf -u URL/FUZZ -w common.txt -mc 200,301,302 |
| 扫 PHP 文件 | ffuf -u URL/FUZZ -w common.txt -e .php -mc 200 |
| 找隐藏参数 | ffuf -u 'URL?FUZZ=1' -w burp-parameter-names.txt -fs SIZE |
| LFI 参数 Fuzz | ffuf -u 'URL?FUZZ=../../../etc/passwd' -w Fuzz_param.txt -mr 'root:' |
| 子域名枚举 | ffuf -u URL -H 'Host: FUZZ.target' -w subdomains.txt -fs SIZE |
| 暴力登录 | ffuf -u URL -X POST -d 'user=admin&pass=FUZZ' -w passwords.txt -fc 401 |
| API 端点发现 | ffuf -u URL/api/FUZZ -w api-endpoints.txt -mc 200,401,403 |
| 备份文件搜索 | ffuf -u URL/FUZZ -w common.txt -e .bak,.zip,.tar.gz,.sql -mc 200 |
注意事项
-ac自动校准非常实用——自动检测默认响应并过滤,减少手动设置-fs的麻烦- ffuf 默认 40 线程,对弱目标可能过快导致 429/封 IP,降到
-t 10 -p 0.1 - 字典路径:SecLists 通常在
/usr/share/seclists/,AboutSecurity 字典在/pentest/AboutSecurity/Dic/ - POST Fuzz 必须指定 Content-Type 头,否则服务端可能不解析
- 多位置 Fuzz 默认是 clusterbomb(笛卡尔积),大字典时组合数爆炸,注意字典大小
