Verificação Insuficiente da Autenticidade de Dados

O software recebe dados de uma fonte externa (requisição HTTP, arquivo, API, mensagem) mas não valida adequadamente se eles realmente vêm de quem diz vir, ou se não foram alterados no caminho. Isso permite que um atacante falsifique ou modifique dados e o sistema os processe como legítimos, causando desde injeção de código até manipulação de lógica de negócio.

Example

Uma API de pagamento que recebe um JSON com status='pagamento confirmado' mas não verifica assinatura HMAC ou JWT. Um atacante intercepta a resposta, altera o status para 'aprovado' e envia de volta; o servidor processa como válido. Outro caso: um formulário que aceita um 'user_id' do cliente sem validar se aquele usuário é quem está fazendo a requisição.

How to mitigate

Use assinaturas criptográficas (HMAC-SHA256, RSA, ECDSA) ou tokens assinados (JWT) para dados críticos; valide origem com CORS e referer headers; nunca confie em dados do cliente sem verificação no servidor; implemente rate limiting e detecção de anomalias para detectar tentativas de manipulação em tempo real.
