Common Security Vulnerabilities in Web Application Development

When developing a web application, it is crucial for developers to be aware of and address various security vulnerabilities to ensure the protection of sensitive data and prevent cyber attacks. Some common security vulnerabilities that developers should be aware of include:

• Cross-Site Scripting (XSS): This vulnerability allows malicious users to inject scripts into web pages viewed by other users.
• SQL Injection: Hackers can exploit this vulnerability to access or manipulate a website's database, potentially leading to data breaches.
• Cross-Site Request Forgery (CSRF): Attackers can trick users into executing unintended actions on a website, such as changing account settings or making transactions.
• Insecure Direct Object References (IDOR): This vulnerability occurs when an application exposes internal implementation objects to users, allowing unauthorized access to sensitive data.
• Security Misconfigurations: Improperly configured settings, such as default passwords or unnecessary services, can provide avenues for attackers to exploit a web application.

By proactively addressing these security vulnerabilities and implementing secure coding practices, developers can enhance the resilience of their web applications against potential threats.
