Conseguenze comuni
| Ambito | Impatto | Probabilità |
|---|---|---|
| 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. |
Detection Methods
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.)Effectiveness : High
Note sulla mappatura delle vulnerabilità
Giustificazione : 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.Commento : 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.
