Web Security Vulnerabilities

A comprehensive demonstration of common web security vulnerabilities and how to protect against them

About This Project

This project demonstrates 12 common web security vulnerabilities with interactive examples. Each demonstration includes:

Educational Purposes Only: These demonstrations are for educational purposes only. Never attempt these exploits on real websites without explicit permission.

SQL Injection High Risk

SQL injection is a code injection technique that exploits vulnerabilities in database queries. Attackers can manipulate queries to bypass authentication, extract data, or even delete information.

Impact: Data theft, authentication bypass, data loss

View Demo

Clickjacking Medium Risk

Clickjacking is a UI redress attack where attackers overlay transparent elements over legitimate buttons, tricking users into clicking malicious elements.

Impact: Unwanted actions, account compromise

View Demo

Cross-Site Scripting (XSS) High Risk

XSS allows attackers to inject client-side scripts into web pages viewed by others. This can lead to session hijacking, credential theft, and more.

Impact: Session hijacking, phishing, content manipulation

View Demo

Cross-Site Request Forgery High Risk

CSRF forces authenticated users to execute unwanted actions on websites where they're logged in, by tricking them into making requests without their knowledge.

Impact: Unauthorized actions, account changes

View Demo

Insecure Direct Object References High Risk

IDOR occurs when an application exposes a reference to an internal implementation object, allowing attackers to manipulate references to access unauthorized data.

Impact: Unauthorized data access, privacy violations

View Demo

Server-Side Request Forgery High Risk

SSRF allows attackers to induce the server to make requests to unintended locations, potentially accessing internal services or sensitive data.

Impact: Access to internal services, data theft

View Demo

XML External Entity Injection High Risk

XXE attacks target applications that parse XML input, potentially leading to disclosure of confidential data, server-side request forgery, or denial of service.

Impact: File disclosure, SSRF, DoS

View Demo

Local Storage Vulnerabilities Medium Risk

Browser storage mechanisms like localStorage can be vulnerable if sensitive data is stored insecurely, making it accessible to any JavaScript on the same origin.

Impact: Data exposure, credential theft

View Demo

Content Security Policy Bypass Medium Risk

CSP helps prevent XSS and other code injection attacks, but weak configurations can be bypassed, allowing attackers to execute malicious scripts.

Impact: Script execution, XSS

View Demo

DOM-based Vulnerabilities Medium Risk

DOM-based vulnerabilities occur when client-side JavaScript processes data from an untrusted source in an unsafe way, leading to exploitable DOM modifications.

Impact: Script execution, data theft

View Demo

HTTP Response Splitting Medium Risk

Response splitting occurs when attackers inject newline characters into response headers, allowing them to add their own headers or inject content into the response.

Impact: Cache poisoning, XSS

View Demo

Password Reset Flaws High Risk

Password reset functionality is critical for security but often contains vulnerabilities like predictable tokens, missing expiration, or insufficient validation.

Impact: Account takeover, privilege escalation
