常見後果
| 範圍 | 影響 | 可能性 |
|---|---|---|
| Confidentiality Integrity | Read Files or Directories, Modify Files or Directories 注意：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 注意：Accessing a file descriptor that has been closed can cause a crash. |

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.
