Function Call With Incorrect Order of Arguments
Draft Variant
Structure: Simple
Description
The product calls a function, procedure, or routine, but the caller specifies the arguments in an incorrect order, leading to resultant weaknesses.
While this weakness might be caught by the compiler in some languages, it can occur more frequently in cases in which the called function accepts variable numbers or types of arguments, such as format strings in C. It also can occur in languages or environments that do not enforce strong typing.
Common Consequences 1
Scope: Other
Impact: Quality Degradation
Potential Mitigations 2
Phase: Implementation
Use the function, procedure, or routine as specified.
Phase: Testing
Because this function call often produces incorrect behavior it will usually be detected during testing or normal operation of the product. 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.
