Falhas do tipo CWE-755

243 resultados

Tratamento inadequado de condições excepcionais

É quando o código não trata, trata de forma insuficiente ou de forma errada situações de erro e exceções. Isso pode deixar o software em estado inconsistente, ignorar falhas críticas ou executar código perigoso quando algo dá errado, compromentendo segurança, integridade ou disponibilidade.

Exemplo

Um servidor Web recebe uma requisição mal formada e falha ao parsear JSON; em vez de retornar erro 400, simplesmente pula a validação e processa dados vazios, ou uma conexão de banco de dados cai e a aplicação continua operando com dados em cache desatualizado sem avisar o usuário.

Como mitigar

Sempre trate exceções explicitamente: capture erros conhecidos e faça rollback/limpeza apropriada, log de falhas para auditoria, e retorne respostas claras ao usuário. Use type hints e validação de entrada antes de processar, e considere parar o sistema de forma segura se a exceção for crítica.
