Secure Coding Practices Questions
Some common security vulnerabilities in web applications include:
1. Cross-Site Scripting (XSS): This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users, leading to unauthorized access, data theft, or session hijacking.
2. SQL Injection: This vulnerability occurs when an attacker inserts malicious SQL code into a web application's database query, allowing them to manipulate or extract sensitive data.
3. Cross-Site Request Forgery (CSRF): This vulnerability tricks users into performing unintended actions on a web application, often leading to unauthorized changes or data disclosure.
4. Insecure Direct Object References (IDOR): This vulnerability allows attackers to directly access and manipulate sensitive data or resources by modifying parameters or object references in a web application's URL.
5. Server-Side Request Forgery (SSRF): This vulnerability enables attackers to make requests from the server to other internal or external resources, potentially leading to data exposure or unauthorized access.
6. Remote Code Execution (RCE): This vulnerability allows attackers to execute arbitrary code on a web server, leading to complete control over the application and potential data breaches.
7. Security Misconfigurations: These vulnerabilities occur when web applications are not properly configured, leaving them open to attacks such as unauthorized access, information disclosure, or privilege escalation.
8. Session Management Issues: Weak session management can lead to session hijacking, session fixation, or session replay attacks, allowing unauthorized access to user accounts or sensitive data.
9. Unvalidated Input: Failure to properly validate and sanitize user input can lead to various vulnerabilities, including XSS, SQL injection, and command injection.
10. Insecure File Uploads: This vulnerability allows attackers to upload malicious files, which can lead to code execution, data breaches, or server compromise.
It is important for developers to be aware of these vulnerabilities and follow secure coding practices to mitigate the risks associated with them.
