CWE-248 (未捕获的异常) — Vulnerability Class 156

CWE-248, Uncaught Exception, represents a critical software weakness where a function throws an error that the calling code fails to handle. This oversight typically allows attackers to exploit the vulnerability by triggering specific conditions that force the application to crash, resulting in a denial of service. Alternatively, the unhandled exception may cause the system to dump detailed stack traces or internal state information to the user interface, inadvertently exposing sensitive data such as database credentials or server architecture. To mitigate this risk, developers must implement robust error handling mechanisms, ensuring that all potential exceptions are explicitly caught and managed. By using try-catch blocks and providing generic, non-revealing error messages, programmers can maintain application stability and prevent information leakage, thereby securing the software against both availability attacks and data exposure.
