CAPEC 113

An attacker manipulates the processing of Application Programming Interface (API) resulting in the API's function having an adverse impact upon the security of the system or application implementing the API. This can allow the attacker to execute functionality not intended by the API implementation, possibly compromising the system or application which integrates the API. API Abuse can take on a number of forms. For example, the API may trust that the calling function properly validates its data and thus it may be manipulated by supplying metacharacters or alternate encodings as input, resulting in any number of injection flaws, including SQL injection, cross-site scripting, or command execution. Another example could be API methods that should be disabled in a production application but were not, thus exposing dangerous functionality within a production environment.
