Divisão por zero

Fraqueza em que o código tenta dividir um número por zero sem validação prévia, causando crash, exceção ou comportamento indefinido. O risco varia: em alguns casos gera apenas erro aritmético; em outros, permite negação de serviço ou exploração mais grave dependendo do contexto de execução.

Example

Uma API recebe um parâmetro do usuário, aplica-o diretamente como divisor sem checar se é zero: `resultado = 100 / parametro_do_usuario`. Se o atacante enviar 0, a aplicação quebra ou trava, indisponibilizando o serviço.

How to mitigate

Validar sempre o divisor antes de usá-lo: checar se é diferente de zero e rejeitar ou tratar o caso com valor padrão. Em linguagens modernas, usar exceptions tipadas e logging para sinalizar tentativas suspeitas.
