Web Application Security: Understanding Vulnerabilities And Bug Bounty Programs

Web application security is a critical aspect of cybersecurity, focusing on identifying and mitigating vulnerabilities in web applications. With the rise of bug bounty programs, security researchers are increasingly contributing to the safety of web applications by reporting vulnerabilities.

You Should Know:

1. Common Web Vulnerabilities:

SQL Injection: Exploiting database queries to gain unauthorized access.
```
sqlmap -u "http://example.com/page?id=1" --dbs
```
Cross-Site Scripting (XSS): Injecting malicious scripts into web pages.
```
<script>alert('XSS')</script>
```

Cross-Site Request Forgery (CSRF): Forcing users to execute unwanted actions on a web application.
