CWE-217: DEPRECATED: Failure to Protect Stored Data from Modification
Learn about CWE-217 (DEPRECATED: Failure to Protect Stored Data from Modification), its security impact, exploitation methods, and prevention guidelines.
What is DEPRECATED: Failure to Protect Stored Data from Modification?
• Overview: CWE-217 is a deprecated entry that originally referred to the failure to protect stored data from unauthorized modification. This weakness involved scenarios where data storage systems did not have adequate security measures to prevent modifications by unauthorized actors.
• Exploitation Methods:
- Attackers could exploit this vulnerability by gaining unauthorized access to a data storage system and modifying the stored data.
- Common attack patterns included unauthorized data tampering, SQL injection to alter database contents, and exploiting weak file permissions on storage systems.
• Security Impact:
- Direct consequences of successful exploitation included data corruption, loss of data integrity, and potential data breaches.
- Potential cascading effects could involve compromised systems due to altered data, leading to faulty operations and decision-making based on incorrect information.
- Business impact might include loss of customer trust, legal consequences, and financial loss due to data integrity issues.
• Prevention Guidelines:
- Specific code-level fixes include implementing robust access controls, validating input to prevent injection attacks, and using cryptographic measures to ensure data integrity.
- Security best practices involve regular audits of data storage systems, applying the principle of least privilege, and using secure coding practices.
- Recommended tools and frameworks include using encryption libraries for data protection, database management systems with built-in security features, and access control systems to manage user permissions effectively.
