// Web fingerprinting and WAF detection using wafw00f, whatweb, nuclei, and httpx. Use this skill when user needs to identify web technologies, detect WAF/CDN, analyze server headers, or fingerprint web applications and frameworks.
按照标准格式生成渗透测试报告，包含项目信息表、漏洞发现清单、漏洞详情（含属性表、描述、复现步骤、证据截图、修复建议）、附录（风险等级定义、CVSS说明、词汇表）。当用户要求生成渗透测试报告、安全测试报告、漏洞报告时使用此技能。严格遵循项目模板目录中的标准格式。
任意文件下载与本地文件包含 (LFI) 漏洞检测和利用工具。使用 curl、ffuf、wget 等工具测试文件下载漏洞，支持路径遍历、伪协议利用、敏感文件读取。当用户需要测试文件下载功能、检测 LFI 漏洞、读取服务器敏感文件时使用此技能。
本地文件包含 (LFI) 漏洞检测和利用工具。使用 curl、ffuf 等工具测试 LFI 漏洞，支持路径遍历、PHP 伪协议利用、日志投毒 RCE、敏感文件读取。当用户需要检测 LFI 漏洞、利用文件包含漏洞读取服务器文件时使用此技能。
Arbitrary file download vulnerability detection and exploitation using path traversal techniques, bypass methods, and sensitive file discovery. Use this skill when user needs to test for file download vulnerabilities, path traversal, or read sensitive files on target systems.
SQL injection detection and exploitation using sqlmap, manual techniques, and custom payloads. Use this skill when user needs to test for SQL injection vulnerabilities, extract database information, or exploit SQLi in parameters, headers, or cookies.
Cross-site scripting (XSS) vulnerability detection and exploitation. Supports reflected XSS, stored XSS, DOM-based XSS, and blind XSS testing. Use this skill when user mentions XSS, cross-site scripting, script injection, or needs to test JavaScript injection in parameters, forms, headers, or DOM sources.

IMPORTANT: Web fingerprinting sends requests to target servers. Always ensure you have:
Required tools that must be installed on your system:
go install -v github.com/projectdiscovery/httpx/cmd/httpx@latestgo install -v github.com/projectdiscovery/nuclei/v2/cmd/nuclei@latestOptional tools:
pip install wafw00fgo install github.com/praetorian-inc/fingerprintx/cmd/fingerprintx@latestMost commonly used commands for web fingerprinting:
whatweb https://target.com
wafw00f https://target.com
curl -I https://target.com
nuclei -u https://target.com -tags tech
When you need to quickly identify the technology stack:
whatweb https://target.com --aggression 1
Parameters:
--aggression 1 - Quick scan (1-4, default 1)-a 3 - More aggressive (more requests)-v - Verbose outputExample:
whatweb https://target.com -a 3
When you need to detect WAF/CDN protection:
wafw00f https://target.com
Output shows:
Check multiple targets:
wafw00f -i targets.txt
When you need to analyze HTTP headers:
curl -I https://target.com
Detailed headers:
curl -v https://target.com 2>&1 | grep -i "< "
Common headers to check:
Server: nginx/1.18.0
X-Powered-By: PHP/7.4
X-AspNet-Version: 4.0.30319
X-Frame-Options: SAMEORIGIN
X-Content-Type-Options: nosniff
Strict-Transport-Security: max-age=31536000
When you need comprehensive technology fingerprinting:
nuclei -u https://target.com -tags tech -severity info
Specific technologies:
nuclei -u https://target.com -tags "wordpress,joomla,drupal"
nuclei -u https://target.com -tags "spring-boot,struts2"
nuclei -u https://target.com -tags "react,vue,angular"
When you need fast HTTP probing with tech detection:
httpx -u https://target.com -tech-detect -status-code -title
Parameters:
-tech-detect - Enable technology detection-status-code - Show HTTP status-title - Extract page title-server - Show server header-websocket - Detect WebSocket-cdn - Detect CDNExample:
httpx -u https://target.com -tech-detect -server -cdn -ssl
When you need to identify the CMS:
whatweb https://target.com --aggression 3 | grep -i cms
Nuclei CMS detection:
nuclei -u https://target.com -tags cms
Common CMS indicators:
/wp-login.php, /wp-admin/, wp-json/user/login, Drupal.settings/administrator/components, Joomla!/typo3confWhen you need to identify frontend frameworks:
curl -s https://target.com | grep -i "react\|vue\|angular\|jquery"
Check specific framework files:
# React
curl -s https://target.com | grep -i "react"
# Vue.js
curl -s https://target.com | grep -i "vue\.js\|vue-"
# Angular
curl -s https://target.com | grep -i "angular\|ng-app"
# jQuery
curl -s https://target.com | grep -i "jquery"
When you need to identify server software and version:
nmap -sV -p 443,80 target.com
HTTP server banner:
curl -I https://target.com | grep -i server
Use httpx for server detection:
httpx -u https://target.com -server -response-time
When you need to identify CDN providers:
httpx -u https://target.com -cdn
Check HTTP headers for CDN:
curl -I https://target.com | grep -i "cf-ray\|x-amz\|x-akamai\|x-fastly"
Common CDN headers:
cf-ray, cf-cache-statusx-amz-cf-idx-akamai-transformedx-served-by, fastly-sslvia, x-amz-cf-popWhen you need to analyze SSL configuration:
nmap --script ssl-cert,ssl-enum-ciphers -p 443 target.com
SSL info with curl:
curl -vI https://target.com 2>&1 | grep -i ssl
Using testssl.sh:
testssl.sh https://target.com
