Weaknesses of type CWE-755

274 results

Tratamento inadequado de condições excepcionais

Ocorre quando o código falha em capturar, validar ou responder adequadamente a erros e situações anormais. O programa continua executando com estado inválido, ignorando sinais de falha do sistema ou bibliotecas, permitindo que bugs se propaguem e criem vulnerabilidades de segurança.

Example

Uma aplicação tenta abrir um arquivo sem verificar se a operação falhou; se o arquivo não existe, a variável fica nula, e acessá-la depois causa crash ou comportamento impredizível. Ou um banco de dados retorna erro, mas o código ignora e usa dados vazios como válidos.

How to mitigate

Sempre capture exceções e erros explicitamente — use try/catch, verifique códigos de retorno e valores nulos antes de usar. Registre falhas em logs, falhe de forma segura (recuse a operação) e nunca assuma que uma chamada de função funcionou sem comprovação.
