What is the problem?

The product calls a function, procedure, or routine with arguments that are not correctly specified, leading to always-incorrect behavior and resultant weaknesses.

Extended description

There are multiple ways in which this weakness can be introduced, including: - the wrong variable or reference; - an incorrect number of arguments; - incorrect order of arguments; - wrong type of arguments; or - wrong value.

Affected security scopes: Other, Access Control

This weakness can cause unintended behavior and can lead to additional weaknesses such as allowing an attacker to gain unintended access to system resources.

Build and Compilation

Detail

Once found, these issues are easy to fix. Use code inspection tools and relevant compiler features to identify potential violations. Pay special attention to code that is not likely to be exercised heavily during QA.

Architecture and Design

Architecture and design approach

Detail

Make sure your API's are stable before you use them in production code.

Verification

How is it detected?

Other

Since these bugs typically introduce incorrect behavior that is obvious to users, they are found quickly, unless they occur in rarely-tested code paths. Managing the correct number of arguments can be made more difficult in cases where format strings are used, or when variable numbers of arguments are supported.
