常见后果

影响范围 影响 可能性
OtherQuality Degradation

注意： Dead code that results from code that can never be executed is an indication of problems with the source code that needs to be fixed and is an indication of poor quality.
OtherReduce Maintainability
OtherVaries by Context, Execute Unauthorized Code or Commands

注意： In some cases, dead code can be reachable or exploitable by attackers after they exploit another weakness or vulnerability that can access the code. For example, some buffer overflow exploits could modify addresses to point to locations that contain dead code.

参考资料 描述

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.

潜在缓解措施

Phases : Implementation
Remove dead code before deploying the application.

漏洞映射说明

依据 : This CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities. However, the term "dead code" might have multiple interpretations.
备注 : Carefully read both the name and description to ensure that this mapping is an appropriate fit. Do not try to 'force' a mapping to a lower-level Base/Variant simply to comply with this preferred level of abstraction.
