Improper Handling of Parameters
The software does not properly handle when the expected number of parameters, fields, or arguments is not provided in input, or if those parameters are undefined.
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.
This application has registered to handle a URL when sent an intent:
The application assumes the URL will always be included in the intent. When the URL is not present, the call to getStringExtra() will return null, thus causing a null pointer exception when length() is called.
This category identifies Software Fault Patterns (SFPs) within the Incorrect Input Handling cluster.
Weaknesses in this category are typically found in functionality that processes data. Data processing is the manipulation of input to retrieve or save information.
This view (slice) covers all the elements in CWE.
CWE identifiers in this view are weaknesses that do not have associated Software Fault Patterns (SFPs), as covered by the CWE-888 view. As such, they represent gaps in...
This view (slice) lists weaknesses that can be introduced during implementation.
