Validação inadequada de índice de array

Ocorre quando o código não valida corretamente um índice antes de acessar um array, permitindo que valores fora dos limites sejam usados. Isso pode causar leitura ou escrita de memória inválida, levando a crash, vazamento de dados ou execução de código arbitrário.

Ejemplo

Uma aplicação recebe um ID de usuário via parâmetro HTTP e o usa diretamente como índice em um array de sessões sem verificar se está dentro dos limites. Um atacante envia um índice negativo ou maior que o tamanho do array, acessando memória adjacente e roubando dados de outras sessões.

Cómo mitigar

Sempre validar que o índice está entre 0 e (tamanho_do_array - 1) antes de qualquer acesso. Use funções de linguagem que impõem limites automaticamente (como iteradores) ou implemente verificações explícitas com exceções/retorno de erro.
