Description: An application logic flaw is a vulnerability that arises from an incorrect implementation of application logic. This type of flaw occurs when the rules and processes governing the behavior of an application are not properly implemented, potentially allowing an attacker to bypass security controls, access sensitive data, or perform unauthorized actions. Often, these flaws result from incorrect assumptions about how users will interact with the application or a lack of validation of user inputs. Application logic flaws are particularly dangerous because they can be difficult to detect during conventional security testing, as they do not always manifest as obvious technical errors. Instead, they may allow an attacker to exploit the business logic of the application to gain unauthorized access or manipulate data. Identifying and correcting these flaws requires careful attention to the design and implementation of application logic, as well as thorough testing that simulates user behavior in various scenarios. The increasing complexity of modern applications, especially those operating in distributed environments or utilizing multiple services, has made application logic flaws a critical area of concern for developers and security professionals.
