Description: Functional vulnerability refers to weaknesses that emerge from the inherent behavior of an application. Unlike technical vulnerabilities, which may be related to coding errors or misconfigurations, functional vulnerabilities are more tied to how users interact with the system and how it responds to those interactions. These vulnerabilities can arise from business logic flaws, poorly designed workflows, or the lack of adequate controls in the application’s functionalities. For example, an application that allows a user to perform unauthorized actions due to faulty authorization logic is a clear example of a functional vulnerability. Identifying these vulnerabilities is crucial, as they can be exploited by attackers to manipulate the application’s behavior, access sensitive data, or perform unwanted actions. Evaluating functional vulnerabilities requires an approach that considers both the technical perspective and the user experience, ensuring that all possible interactions are secure and properly controlled. In an environment where applications are becoming increasingly complex and interconnected, attention to functional vulnerabilities becomes essential to maintain the integrity and security of systems.
