名稱: Use of Function with Inconsistent Implementations

The code uses a function that has inconsistent implementations across operating systems and versions.

名稱： C (Often)
名稱： PHP (Often)
類別： Not Language-Specific (Undetermined)

常見後果

範圍	影響	可能性
Other	Quality Degradation, Varies by Context 注意：The use of inconsistent implementations can cause changes in behavior when the code is ported or built under a different environment than the programmer expects, which can lead to security problems in some cases.

潛在緩解措施

Phases : Architecture and Design // Requirements
Do not accept inconsistent behavior from the API specifications when the deviant behavior increases the risk level.

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.)
有效性 : High

漏洞對應備注

理由說明 : 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.
備註 : 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.
