Web Exploitation Master Learning Path

Web exploitation involves finding and exploiting vulnerabilities in web applications, such as SQL injection, XSS, SSRF, IDOR, and authentication bypass, to gain unauthorized access, manipulate data, or take control of the system.

Common Web Vulnerabilities

1. Cross-Site Scripting (XSS)

XSS allows attackers to inject malicious scripts into web pages viewed by other users. It can be used to steal cookies, session tokens, or other sensitive information.

2. SQL Injection

SQL Injection occurs when an attacker inserts malicious SQL queries into input fields, allowing them to manipulate the database and access unauthorized data.

3. Cross-Site Request Forgery (CSRF)

CSRF tricks users into performing actions they didn't intend to, such as changing account settings or making transactions, by exploiting their authenticated session.

4. File Inclusion Vulnerabilities

These vulnerabilities allow attackers to include files on a server, potentially leading to remote code execution or sensitive data exposure.

5. Insecure Direct Object References (IDOR)

IDOR occurs when an application exposes internal objects (e.g., database keys) without proper authorization checks, allowing attackers to access unauthorized data.

Tools for Web Exploitation

1. Burp Suite

A powerful tool for web application security testing, including scanning for vulnerabilities, intercepting requests, and manipulating data.

2. OWASP ZAP

An open-source web application security scanner designed to find vulnerabilities in web applications.

3. SQLMap

An automated tool for detecting and exploiting SQL injection vulnerabilities.

Techniques for Web Exploitation

1. Fuzzing

Fuzzing involves sending random or malformed data to an application to identify unexpected behavior or vulnerabilities.

2. Reverse Engineering

Analyzing the client-side code (e.g., JavaScript) to understand how the application works and identify potential vulnerabilities.

3. Session Hijacking

Exploiting session management flaws to take over a user's session and gain unauthorized access.

4. Parameter Tampering

Manipulating URL parameters, form fields, or cookies to exploit vulnerabilities in the application.

5. Bypassing Authentication

Exploiting weak authentication mechanisms to gain access to restricted areas of the application.
