Weaknesses of type CWE-248

291 results

Exceção não capturada

Quando o código não trata adequadamente exceções lançadas durante a execução, permitindo que elas se propaguem sem controle. Isso pode expor informações sensíveis em mensagens de erro, causar parada inesperada do serviço ou deixar o sistema em estado inconsistente.

Example

Uma aplicação web que não captura exceções de banco de dados mostra ao usuário o stack trace completo com credenciais, caminho de arquivos ou consultas SQL. Ou um serviço de API que trava quando recebe um JSON malformado, sem retornar um erro controlado ao cliente.

How to mitigate

Implemente blocos try-catch em pontos críticos (I/O, banco de dados, operações sensíveis) e retorne erros genéricos ao usuário. Registre exceções em logs internos com contexto completo, sem expor detalhes técnicos na resposta pública. Use tratadores globais de exceções para garantir comportamento consistente e seguro.
