Classe: Not Language-Specific (Undetermined)Consequências Comuns
| Escopo | Impacto | Probabilidade |
|---|---|---|
| Other | Increase Analytical Complexity Nota: A human auditor might indirectly trust that whitespace (especially indentation) reflects the actual control flow of the code, which could make it more difficult to find vulnerabilities. | |
| Other | Reduce Maintainability Nota: This issue makes it more difficult to understand and maintain the product, which indirectly affects security by making it more difficult or time-consuming to find and/or fix vulnerabilities. |

CVE-2014-1266 | Chain: incorrect "goto" in Apple SSL product bypasses certificate validation, allowing Adversary-in-the-Middle (AITM) attack (Apple "goto fail" bug). CWE-705 (Incorrect Control Flow Scoping) -> CWE-561 (Dead Code) -> CWE-295 (Improper Certificate Validation) -> CWE-393 (Return of Wrong Status Code) -> CWE-300 (Channel Accessible by Non-Endpoint). The code's whitespace indentation did not reflect the actual control flow (CWE-1114) and did not explicitly delimit the block (CWE-483), which could have made it more difficult for human code auditors to detect the vulnerability. |
Métodos de Detecção
Automated Static Analysis
Automated static analysis, commonly referred to as Static Application Security Testing (SAST), can find some instances of this weakness by analyzing source code (or binary/compiled code) without having to execute it. Typically, this is done by building a model of data flow and control flow, then searching for potentially-vulnerable patterns that connect "sources" (origins of input) with "sinks" (destinations where the data interacts with external components, a lower layer such as the OS, etc.)Eficácia : High
Notas de Mapeamento de Vulnerabilidade
Justificativa : This entry is primarily a quality issue with no direct security implications.Comentário : Look for weaknesses that are focused specifically on insecure behaviors that have more direct security implications.
