CAPEC-113: Interface Manipulation

Description
An adversary manipulates the use or processing of an interface (e.g. Application Programming Interface (API) or System-on-Chip (SoC)) resulting in an adverse impact upon the security of the system implementing the interface. This can allow the adversary to bypass access control and/or execute functionality not intended by the interface implementation, possibly compromising the system which integrates the interface. Interface manipulation can take on a number of forms including forcing the unexpected use of an interface or the use of an interface in an unintended way.
Extended Description

Examples of secrets can include, but are not limited to, passwords, encryption keys, database lookup keys, and initial values to one-way functions. The key factor in this attack is the attackers' ability to explore the possible secret space rapidly. This, in turn, is a function of the size of the secret space and the computational power the attacker is able to bring to bear on the problem. If the attacker has modest resources and the secret space is large, the challenge facing the attacker is intractable. Assuming a finite secret space, a brute force attack will eventually succeed. The defender must rely on making sure that the time and resources necessary to do so will exceed the value of the information.

Prerequisites

This table shows the other attack patterns and high level categories that are related to this attack pattern.

  • The target system must expose interface functionality in a manner that can be discovered and manipulated by an adversary. This may require reverse engineering the interface or decrypting/de-obfuscating client-server exchanges.

Taxonomy mappings

Mappings to ATT&CK, OWASP and other frameworks.

Resources required

The requirements vary depending upon the nature of the interface. For example, application-layer APIs related to the processing of the HTTP protocol may require one or more of the following: an Adversary-In-The-Middle (CAPEC-94) proxy, a web browser, or a programming/scripting language.
