CWE-1075: Unconditional Control Flow Transfer outside of Switch Block

What is Unconditional Control Flow Transfer outside of Switch Block?

• Overview: Unconditional Control Flow Transfer outside of Switch Block is a vulnerability where code performs an unconditional jump or control transfer (like a "goto") outside of a structured control flow, such as a switch block. This can make code harder to read and maintain, increasing the risk of introducing new vulnerabilities.

• Exploitation Methods:

• Attackers can exploit this by introducing logic errors that are difficult to detect due to the non-linear control flow, potentially leading to unexpected behavior.
• Common attack patterns include manipulating program execution to bypass security checks or executing unintended code paths.

• Security Impact:

• Direct consequences include reduced code reliability and increased difficulty in debugging, which can lead to overlooked vulnerabilities.
• Potential cascading effects involve making the codebase more susceptible to future errors and security issues due to complex control flow.
• Business impact includes increased maintenance costs and potential vulnerabilities leading to data breaches or system failures.

• Prevention Guidelines:

• Specific code-level fixes include avoiding the use of "goto" statements and ensuring structured programming practices are followed.
• Security best practices involve using clear and maintainable control structures like loops and conditionals, and ensuring code reviews focus on control flow integrity.
• Recommended tools and frameworks include static code analysis tools that can detect irregular control flow patterns and enforce coding standards that discourage the use of unstructured control transfers.
