An adversary exploits a sample, demonstration, test, or debug interface that is unintentionally enabled on a production system, with the goal of gleaning information or leveraging functionality that would otherwise be unavailable. Non-production interfaces are insecure by default and should not be resident on production systems, since they may reveal sensitive information or functionality that should not be known to end-users. However, such interfaces may be unintentionally left enabled on a production system due to configuration errors, supply chain mismanagement, or other pre-deployment activities. For example, some software applications include application programming interfaces (APIs) that are intended to allow an administrator to test and refine their domain. These APIs are typically disabled once a system enters a production environment, but may be left in an insecure state due to a configuration error or mismanagement. Similarly, many hardware systems leverage bits typically reserved for future functionality for testing and debugging purposes. If these reserved bits remain enabled in a production environment, it could allow an adversary to induce unwanted/unsupported behavior in the hardware. Ultimately, failure to properly disable non-production interfaces, in a production environment, may expose a great deal of diagnostic information or functionality to an adversary, which can be utilized to further refine their attack. Moreover, many non-production interfaces do not have adequate security controls or may not have undergone rigorous testing since they were not intended for use in production environments. As such, they may contain many flaws and vulnerabilities that could allow an adversary to severely disrupt a target.
