What are the most common security vulnerabilities found in web applications?

Common Security Vulnerabilities in Web Applications

When it comes to web application security, there are several common vulnerabilities that developers should be aware of. These vulnerabilities can put the application and its users at risk if not properly addressed.

Focus Keyword: security vulnerabilities in web applications

1. SQL Injection

SQL injection is a code injection technique that can expose sensitive information or modify databases. It occurs when an attacker inserts malicious SQL statements into input fields.

2. Cross-Site Scripting (XSS)

XSS allows attackers to inject malicious scripts into web pages viewed by other users. This can lead to the theft of sensitive information, such as cookies or session tokens.

3. Cross-Site Request Forgery (CSRF)

CSRF attacks trick users into executing unauthorized actions on a web application in which they are authenticated. This can lead to fraudulent transactions or data manipulation.

4. Insecure Direct Object References

This vulnerability occurs when an application exposes internal implementation objects, such as files or database records, to users without proper authorization checks.

5. Security Misconfiguration

Security misconfigurations, such as default passwords or improperly configured permissions, can leave web applications vulnerable to attacks. It is essential to regularly audit and update configurations.

It is crucial for developers to understand these common security vulnerabilities in web applications and implement appropriate measures to mitigate them. Regular security assessments and code reviews can help identify and address these vulnerabilities before they are exploited by attackers.
