CWE-573: Improper Following of Specification by Caller
The product does not follow or incorrectly follows the specifications as required by the implementation language, environment, framework, protocol, or platform.
How it's found
Improper Following of Specification by Caller describes a general pattern rather than a single fixed bug. Testers use a mix of static analysis and manual code review to find where a target's code matches this pattern, then confirm exploitability by hand.
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.
