Vulnerability Mapping:
PROHIBITEDThis CWE ID must not be used to map to real-world vulnerabilities Abstraction: BaseBase - a weakness that is still mostly independent of a resource or technology, but with sufficient details to provide specific methods for detection and prevention. Base level weaknesses typically describe issues in terms of 2 or 3 of the following dimensions: behavior, property, technology, language, and resource.

For users who are interested in more notional aspects of a weakness. Example: educators, technical writers, and project/program managers.For users who are concerned with the practical application and details about the nature of a weakness and how to prevent it from happening. Example: tool developers, security researchers, pen-testers, incident response analysts.For users who are mapping an issue to CWE/CAPEC IDs, i.e., finding the most appropriate CWE for a specific issue (e.g., a CVE record). Example: tool developers, security researchers.For users who wish to see all available information for the CWE/CAPEC entry.For users who want to customize what details are displayed.

Description
This entry has been deprecated. There are no documented cases in which a switch's control expression is evaluated more than once.
Extended Description
It is likely that this entry was initially created based on a misinterpretation of the original source material. The original source intended to explain how switches could be unpredictable when using threads, if the control expressions used data or variables that could change between execution of different threads. That weakness is already covered by CWE-367. Despite the ambiguity in the documentation for some languages and compilers, in practice, they all evaluate the switch control expression only once. If future languages state that the code explicitly evaluates the control expression more than once, then this would not be a weakness, but the language performing as designed.
