CWE-1083: Data Access from Outside Expected Data Manager Component
Learn about CWE-1083 (Data Access from Outside Expected Data Manager Component), its security impact, exploitation methods, and prevention guidelines.
What is Data Access from Outside Expected Data Manager Component?
• Overview: This vulnerability occurs when a software product intended to manage data through a specific data manager component, like a database, contains code that accesses data outside of this component. This can violate the design principles and lead to reliability issues or vulnerabilities if the code is accessible by attackers.
• Exploitation Methods:
- Attackers can exploit this vulnerability if they can reach and manipulate the code that accesses data outside the intended component, potentially bypassing security controls.
- Common attack patterns include injecting malicious inputs to alter data access logic or leveraging known weaknesses in the data management code to gain unauthorized access.
• Security Impact:
- Direct consequences include unauthorized data access and potential data corruption or loss.
- Potential cascading effects might involve data integrity issues across systems relying on consistent data states, leading to broader system failures.
- Business impact could involve data breaches, loss of customer trust, regulatory fines, and operational disruptions.
• Prevention Guidelines:
- Specific code-level fixes include ensuring all data access operations strictly use the designated data manager component and auditing existing code for violations.
- Security best practices encompass maintaining a clear separation of concerns in code design, regularly reviewing and testing data access points, and enforcing strict access controls.
- Recommended tools and frameworks involve using static code analysis tools to detect improper data access patterns and employing robust ORM (Object-Relational Mapping) frameworks to handle database operations securely.
