CWE-573: Improper Following of Specification by Caller

Weakness ID: 573
Abstraction: Class
Structure: Simple
Status: Draft
Presentation Filter:
+ Description
The software does not follow or incorrectly follows the specifications as required by the implementation language, environment, framework, protocol, or platform.
+ Extended Description
When leveraging external functionality, such as an API, it is important that the caller does so in accordance with the requirements of the external functionality or else unintended behaviors may result, possibly leaving the system vulnerable to any number of exploits.
+ Relationships

The table(s) below shows the weaknesses and high level categories that are related to this weakness. These relationships are defined as ChildOf, ParentOf, MemberOf and give insight to similar items that may exist at higher and lower levels of abstraction. In addition, relationships such as PeerOf and CanAlsoBe are defined to show similar weaknesses that the user may want to explore.
