Falhas do tipo CWE-248

291 resultados

Exceção não capturada

Ocorre quando o código não trata exceções que podem ser lançadas durante a execução, permitindo que erros se propaghem de forma descontrolada. Isso pode expor informações sensíveis em mensagens de erro, causar travamentos inesperados ou deixar a aplicação em estado inconsistente.

Exemplo

Um endpoint de API que tenta conectar a um banco de dados sem try-catch: se a conexão falhar, a exceção não tratada retorna um stack trace completo ao cliente, revelando caminho do servidor, versões de bibliotecas e estrutura interna do código.

Como mitigar

Envolva operações críticas (I/O, rede, parsing) em blocos try-catch apropriados, registre erros adequadamente em logs internos e retorne mensagens de erro genéricas ao usuário. Implemente um handler global de exceções na aplicação para capturar falhas não previstas.
