背景の詳細
導入モード
Implementation : For some programming languages and constructs, an empty block might be allowed by the syntax. While an empty code block might be intentional, it could accidentally occur when the developer did not finish implementation, accidental code deletion, unexpected macro expansion, etc.

注記:The lack of any behavior within the block might violate a convention or API in such a way that it is an error. It could indicate a situation in which some kind of action should be taken. | |
検出方法
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.)
有効性 : High
脆弱性マッピングノート
理由 : 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.
コメント : 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.
