CWE-1084: Invokable Control Element with Excessive File or Data Access Operations

What is Invokable Control Element with Excessive File or Data Access Operations?

• Overview: This vulnerability occurs when a function or method in software performs too many operations involving data management or file resources. This can make the code complex and hard to maintain, increasing the likelihood of introducing security issues.

• Exploitation Methods:

• Attackers may exploit this by identifying complex functions and inserting malicious code or exploiting existing vulnerabilities within these operations.
• Common attack patterns include injecting code that leverages excessive operations for unauthorized data access or manipulation.

• Security Impact:

• Direct consequences include increased difficulty in vulnerability detection and fixing, potentially leading to overlooked security flaws.
• Potential cascading effects involve introducing new vulnerabilities when developers attempt to modify or refactor complex code.
• Business impact includes increased maintenance costs and potential data breaches resulting from undetected vulnerabilities.

• Prevention Guidelines:

• Specific code-level fixes include refactoring functions to limit the number of data/file operations, ideally adhering to a recommended maximum of 7 operations.
• Security best practices involve regularly reviewing and simplifying complex functions to enhance maintainability and reduce the chance of security issues.
• Recommended tools and frameworks include static analysis tools to detect complex functions and tools that support code refactoring to improve code structure.
