Improper Handling of Undefined Values
The software does not handle or incorrectly handles when a value is not defined or supported for the associated parameter, field, or argument name.
The following examples help to illustrate the nature of this weakness and describe methods or techniques which can be used to mitigate the risk.
Note that the examples here are by no means exhaustive and any given weakness may have many subtle varieties, each of which may require different detection methods or runtime controls.
In this example, an address parameter is read and trimmed of whitespace.
If the value of the address parameter is null (undefined), the servlet will throw a NullPointerException when the trim() is attempted.
