SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires curl, nikto, nmap, whatweb, and includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill helps identify the underlying technologies, frameworks, and versions used by a web application, which is crucial for understanding potential vulnerabilities.

Core Features & Use Cases

  • Technology Identification: Detects web server type, frameworks (e.g., WordPress, Laravel), and specific application versions.
  • Vulnerability Prioritization: Narrows down the attack surface by revealing known CVEs associated with the identified stack.
  • Use Case: Before performing a penetration test, use this skill to quickly understand if the target is running an outdated version of Apache with a known critical vulnerability.

Quick Start

Use the web-fingerprinting skill to identify the technologies used by example.com.

Frequently Asked Questions about web-fingerprinting

High-intent search queries and answers about installing and using this skill.

FAQPage Schema
How do I identify the web technology stack of a target application?▼

Web fingerprinting identifies a target application's technology stack by analyzing HTTP headers, cookies, and source code to detect server types and frameworks. This process scopes reconnaissance for targeted vulnerability assessment and exploit selection.

What is the best way to map a web server version to known security advisories?▼

Mapping a web server version to known security advisories involves using banner grabbing and HTTP header analysis to identify specific versions. This enumeration reveals known CVEs associated with the identified stack for vulnerability prioritization.

How do I perform web reconnaissance using tools like Nikto and WhatWeb?▼

Performing web reconnaissance with tools like Nikto and WhatWeb involves executing scripts to analyze target URLs for server banners and framework signatures. These dependencies automate technology identification to narrow down the application attack surface.

Can I detect specific application frameworks like WordPress during reconnaissance?▼

Detecting specific application frameworks like WordPress is possible through source code review and cookie inspection. The fingerprinting process extracts framework signatures to pinpoint exact application versions running on the target.

Does web fingerprinting require installing external dependencies to work?▼

Web fingerprinting requires installing external dependencies including curl, nikto, nmap, and whatweb. These tools execute the underlying banner grabbing and HTTP analysis scripts needed to identify the target's technologies.

Why use web fingerprinting before starting a penetration test?▼

Use web fingerprinting before a penetration test to quickly discover if a target runs outdated software with known critical vulnerabilities. Identifying the exact technology stack early narrows the attack surface and guides targeted exploit selection.
