CWE-686: Function Call With Incorrect Argument Type
Function Call With Incorrect Argument Type
Weakness ID: 686 (Weakness Variant)
Status: Draft
Description
Description Summary
The software calls a function, procedure, or routine, but the
caller specifies an argument that is the wrong data type, which may lead to
resultant weaknesses.
Extended Description
This weakness is most likely to occur in loosely typed languages, or in
strongly typed languages in which the types of variable arguments cannot be
enforced at compilation time, or where there is implicit casting.
Time of Introduction
Implementation
Potential Mitigations
Phase
Description
Use the function, procedure, routine as specified.
Because this function call often produces incorrect behavior it will
usually be detected during testing or normal operation of the software.
During testing exercise all possible control paths will typically expose
this weakness except in rare cases when the incorrect function call
accidentally produces the correct results or if the provided argument
type is very similar to the expected argument type.
