CAPEC

Common Attack Pattern Enumeration and Classification (CAPEC) is a comprehensive dictionary and classification taxonomy of known attacks that can be used by analysts, developers, testers, and educators to deepen community understanding and enhance protection. The vulnerability has been classificated in 8 categories.

Privilege Escalation

An adversary exploits a weakness enabling them to elevate their privilege and perform an action that they are not supposed to be authorized to perform.

Privilege Abuse

An adversary is able to exploit features of the target that should be reserved for privileged users or administrators but are exposed to use by lower or non-privileged accounts. Access to sensitive information and functionality must be controlled to ensure that only authorized users are able to access these resources

Restful Privilege Elevation

Rest uses standard HTTP (Get, Put, Delete) style permissions methods, but these are not necessarily correlated generally with back end programs. Strict interpretation of HTTP get methods means that these HTTP Get services should not be used to delete information on the server, but there is no access control mechanism to back up this logic

CPE

CPE is a structured naming scheme for information technology systems, software, and packages. Based on a common Uniform Resource Identifier (URI) syntax, CPE includes a formal naming format, a method for validating system names, and a description format for attaching text and tests to the name.
