Confusão de Tipos

Ocorre quando o programa trata uma variável ou objeto como se fosse de um tipo diferente do seu tipo real, levando a comportamentos impredizíveis. O atacante explora essa interpretação errada para contornar validações, corromper memória ou executar código arbitrário.

Example

Um aplicativo recebe um valor que valida como inteiro, mas a função que o processa o interpreta como um ponteiro de memória. O código tenta acessar e modificar dados no endereço apontado, causando corrupção ou exposição de informações sensíveis.

How to mitigate

Implemente validação rigorosa e conversão explícita de tipos antes de usar qualquer dado externo. Use linguagens com verificação forte de tipos em tempo de compilação e, quando necessário, valide tanto o tipo quanto o intervalo de valores esperados. Testes de fuzzing e análise estática ajudam a detectar confusões de tipo.
