Common Examples of Web Application Testing:

To gain a better understanding of the Web Application Testing, let's explore some common examples:

1. Cross-Site Scripting (XSS): Attackers inject malicious scripts into web pages, targeting unsuspecting users. These scripts can steal user credentials, redirect users to malicious websites, or perform unauthorized actions on behalf of the user.

2. SQL Injection: Attackers manipulate user input to execute unauthorized SQL queries, enabling them to access, modify, or delete sensitive data stored in databases.

3. Cross-Site Request Forgery (CSRF): Attackers trick users into unknowingly performing actions on a web application, such as changing their password or making unauthorized transactions.

These examples highlight the potential risks associated with Web Application Testing and the need for robust security measures.

Risks and Consequences:

The Web Application Testing poses several risks and consequences for both developers and users. Understanding these risks is crucial in order to prioritize security measures and mitigate potential damage.
