Verificação inadequada da origem de um canal de comunicação

A aplicação aceita dados ou comandos de um canal de comunicação sem verificar adequadamente se a origem é realmente confiável. Isso permite que um atacante se faça passar por um componente legítimo — servidor, cliente, módulo interno — e injete dados maliciosos ou comandos não autorizados.

Example

Um serviço backend recebe requisições em um socket ou fila de mensagens sem validar se o remetente é autenticado; um atacante se conecta à mesma fila e envia comandos administrativos forjados, conseguindo alterar configurações da aplicação.

How to mitigate

Implemente autenticação obrigatória (certificados, tokens, chaves) antes de aceitar qualquer dado do canal; valide a identidade da origem em cada mensagem e rejeite tudo que não puder ser verificado. Use criptografia e assinatura digital para garantir integridade e origem.
