Tratamento inadequado de condições de erro

Quando o código não verifica ou trata corretamente situações anormais (erros, exceções, valores inesperados), ele pode se comportar de forma impredizível ou insegura. O programa segue um caminho que não deveria, ignorando sinais de falha que poderiam evitar consequências maiores.

Example

Um serviço lê um arquivo de configuração sem verificar se a leitura falhou; se o arquivo não existir, as variáveis ficam vazias ou com lixo de memória, e o programa usa valores inválidos em decisões críticas de segurança, abrindo brechas para ataques.

How to mitigate

Sempre capture e trate exceções explicitamente, valide retornos de função (códigos de erro, null, valores fora do escopo), e log eventos anômalos. Implemente fallbacks sensatos e recuse operações quando o estado não for confiável.
