CWE-365: DEPRECATED: Race Condition in Switch

What is DEPRECATED: Race Condition in Switch?

• Overview:

CWE-365, "Race Condition in Switch," refers to a deprecated security vulnerability that was initially believed to occur when a switch statement's control expression was evaluated more than once, potentially leading to unpredictable behavior in multi-threaded contexts. It is now understood that this scenario does not occur in practice as switch control expressions are evaluated only once. The concern that existed is already covered by a different weakness, CWE-367.

• Exploitation Methods:

This specific vulnerability cannot be exploited because it does not occur in practice.
Misunderstandings about this vulnerability could lead developers to incorrectly assume risks that do not exist.

• Security Impact:

There are no direct consequences of this vulnerability as it is not a valid security issue.
No potential cascading effects exist due to this deprecated vulnerability.
The business impact is negligible as this is not an active threat.

• Prevention Guidelines:

Ensure understanding of how switch statements work in the languages you are using; they evaluate control expressions once.
Familiarize yourself with actual race condition vulnerabilities like those covered under CWE-367.
Follow best practices for thread safety and concurrency to avoid genuine race conditions.
Use static analysis tools to detect race conditions and other concurrency issues in your code.
