Validação inadequada de certificado SSL/TLS

A aplicação falha em validar corretamente o certificado SSL/TLS do servidor remoto, aceitando certificados inválidos, expirados ou de hosts diferentes. Isso permite ataques man-in-the-middle onde um atacante intercepta a comunicação sem ser detectado, comprometendo a confidencialidade e integridade dos dados.

Example

Uma app mobile que desativa a verificação de certificado para 'facilitar testes' acaba em produção; um atacante na mesma rede Wi-Fi intercepta requisições HTTPS para roubar tokens de autenticação ou dados sensíveis sem que a app perceba.

How to mitigate

Sempre validar o certificado do servidor (hostname, cadeia de certificados, data de validade), nunca desabilitar verificações em produção, e usar apenas bibliotecas atualizadas que implementam corretamente as regras de validação de TLS.
