CWE - 478 : Missing Default Case in Switch Statement

CWE Definition http://cwe.mitre.org/data/definitions/478.html
Number of vulnerabilities: 0
Description The code does not have a default case in a switch statement, which might lead to complex logical errors and resultant weaknesses.
Background Details
Other Notes This flaw represents a common problem in software development, in which not all possible values for a variable are considered or handled by a given process. Because of this, further decisions are made based on poor information, and cascading failure results. This cascading failure may result in any number of security issues, and constitutes a significant failure in the system. In the case of switch style statements, the very simple act of creating a default case can mitigate this situation, if done correctly. Often however, the default cause is used simply to represent an assumed option, as opposed to working as a sanity check. This is poor practice and in some cases is as bad as omitting a default case entirely.
