TryHackMe: ORM Injection
- Object-relational Mapping (ORM) acts as a bridge between object-oriented and relational database models, converting data seamlessly.
- Commonly used ORM frameworks include Doctrine for PHP, Hibernate for Java, SQLAlchemy for Python, Entity Framework for C#, and Active Record for Ruby on Rails.
- Configuring Laravel's Eloquent ORM involves steps like installing Laravel, setting up database credentials, creating migrations, and running migrations.
- Security considerations for ORM involve ensuring proper Migrations setup to prevent ORM injection vulnerabilities.
- Identifying ORM injection involves techniques like manual code review, automated scanning, input validation testing, and error-based testing.
- Key security measures for preventing ORM injection include using parameterized queries, avoiding raw queries, and ensuring input validation and sanitization.
- Frameworks like Laravel, Ruby on Rails, Django, Spring, and Node.js have their own ORM libraries and common vulnerable methods.
- Best practices to prevent SQL injection include input validation, parameterized queries, proper ORM usage, and escaping/sanitization.
- Doctrine, SQLAlchemy, Hibernate, and Entity Framework provide examples of preventing SQL injection by using parameterized queries in their respective languages.
- A vulnerable implementation using Laravel's Eloquent ORM illustrates the risk of ORM injection, while a secure implementation shows the importance of using methods like where() for query security.
- A case of Laravel Query Builder SQL Injection Vulnerability (Pre 1.17.1) demonstrates the exploitation of unsanitized query parameters for malicious SQL injection.
