| Other | Varies by Context Ghi chú: The consequences will vary depending on how the operation works. This may depend on whether the responsibility for avoiding multiple operations is placed on the developer (which may be more risky), or whether there is built-in protection to prevent multiple invocations or handle them cleanly ("no action" or some kind of error report). |

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.)Ghi chú ánh xạ lỗ hổng

Ghi chú
This weakness is probably closely associated with other issues related to doubling, such as CWE-462 (duplicate key in alist) or CWE-102 (Struts duplicate validation forms). It's usually a case of an API contract violation (CWE-227).Gửi
