Secure Coding Practices Questions
Some common security vulnerabilities in web services include:
1. Injection attacks: This occurs when untrusted data is sent to an interpreter as part of a command or query, leading to unauthorized access or manipulation of data.
2. Cross-Site Scripting (XSS): This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to session hijacking or data theft.
3. Cross-Site Request Forgery (CSRF): This vulnerability allows attackers to trick authenticated users into performing unwanted actions on a web application, leading to unauthorized changes or data leakage.
4. XML External Entity (XXE) attacks: This vulnerability allows attackers to exploit weakly configured XML parsers, leading to disclosure of internal files, denial of service, or server-side request forgery.
5. Broken authentication and session management: Weak or improper implementation of authentication and session management mechanisms can lead to unauthorized access, session hijacking, or session fixation attacks.
6. Insecure direct object references: This vulnerability occurs when an application exposes internal implementation objects, such as database keys or file paths, allowing attackers to manipulate or access unauthorized data.
7. Security misconfigurations: Poorly configured web servers, databases, or application frameworks can expose sensitive information or provide unauthorized access to attackers.
8. Insecure deserialization: This vulnerability occurs when untrusted data is deserialized without proper validation, leading to remote code execution, denial of service, or data tampering.
9. Insufficient input validation: Lack of proper input validation can lead to various attacks, such as buffer overflows, SQL injection, or command injection.
10. Unvalidated redirects and forwards: This vulnerability allows attackers to redirect users to malicious websites or perform phishing attacks by manipulating unvalidated redirect or forward URLs.
