Secure Coding Practices Questions
Some common security vulnerabilities in database applications include:
1. SQL Injection: This occurs when an attacker is able to manipulate SQL queries by inserting malicious code into user input fields, potentially allowing them to access, modify, or delete sensitive data.
2. Cross-Site Scripting (XSS): This vulnerability allows attackers to inject malicious scripts into web pages viewed by other users, potentially leading to the theft of sensitive information or unauthorized actions.
3. Insecure Direct Object References: This vulnerability occurs when an application exposes direct references to internal database objects, allowing attackers to manipulate or access unauthorized data.
4. Cross-Site Request Forgery (CSRF): This vulnerability allows attackers to trick authenticated users into performing unintended actions on a web application, potentially leading to unauthorized data modifications or access.
5. Inadequate Authentication and Authorization: Weak or improperly implemented authentication and authorization mechanisms can allow unauthorized access to sensitive data or functionalities.
6. Insecure Configuration: Misconfigurations in database settings, such as weak passwords, default credentials, or unnecessary open ports, can expose the database to unauthorized access or attacks.
7. Information Leakage: This vulnerability occurs when an application unintentionally reveals sensitive information, such as error messages or stack traces, which can be exploited by attackers to gain knowledge about the system and potentially launch further attacks.
8. Lack of Input Validation: Failing to properly validate and sanitize user input can lead to various vulnerabilities, including SQL injection, XSS, and command injection.
9. Insecure Session Management: Weak session management practices, such as using predictable session IDs or not properly expiring sessions, can allow attackers to hijack user sessions and gain unauthorized access to the application.
10. Denial of Service (DoS): Database applications can be vulnerable to DoS attacks, where an attacker overwhelms the system with excessive requests or resource consumption, causing the application to become unavailable to legitimate users.
