CWE-1056: Invokable Control Element with Variadic Parameters

What is Invokable Control Element with Variadic Parameters?

• Overview: Invokable Control Element with Variadic Parameters (CWE-1056) refers to a function or method that allows a variable number of arguments. This flexibility can make it challenging to determine which function or method is being executed, complicating code analysis and potentially leading to reliability issues.

• Exploitation Methods:

• Attackers can exploit this vulnerability by passing unexpected arguments to manipulate the control flow or behavior of the application.
• Common attack patterns include injecting malicious data or commands through variadic parameters, leading to unintended execution paths.

• Security Impact:

• Direct consequences include unpredictable program behavior, which can lead to crashes or unintended operations.
• Potential cascading effects involve security vulnerabilities such as buffer overflows or injection attacks if the variadic parameters are not handled securely.
• Business impact may include data breaches, service disruptions, or loss of customer trust due to compromised application reliability.

• Prevention Guidelines:

• Specific code-level fixes include avoiding the use of variadic parameters when unnecessary and validating all input data thoroughly.
• Security best practices involve using fixed parameter lists when possible and employing strict type-checking and input validation mechanisms.
• Recommended tools and frameworks include static code analysis tools to detect variadic parameter usage and adopting secure coding standards that discourage or limit their use.
