Consequências Comuns
| Escopo | Impacto | Probabilidade |
|---|---|---|
| Confidentiality Integrity | Read Files or Directories, Modify Files or Directories Nota: The reused file descriptor might reference a different file or device than the original file descriptor. As a result, the program could read data from, or write data to, the wrong file. | |
| Availability | DoS: Crash, Exit, or Restart Nota: Accessing a file descriptor that has been closed can cause a crash. |
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 CWE entry is at the Base level of abstraction, which is a preferred level of abstraction for mapping to the root causes of vulnerabilities.Comentário : 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.
