Validação inadequada de certificado SSL/TLS

A aplicação não valida corretamente o certificado SSL/TLS do servidor remoto, aceitando certificados inválidos, expirados ou emitidos por autoridades não confiáveis. Isso permite que um atacante em posição de intermediário (man-in-the-middle) intercepte a comunicação criptografada e acesse dados sensíveis que deveriam estar protegidos.

Exemplo

Uma aplicação mobile conecta a uma API via HTTPS mas ignora erros de validação de certificado (ou desabilita a verificação para 'facilitar testes'). Um atacante na mesma rede WiFi consegue interceptar requisições, roubar tokens de autenticação ou credenciais do usuário.

Como mitigar

Sempre validar o certificado do servidor (hostname, cadeia de confiança, data de validade). Em desenvolvimento, use certificados válidos mesmo em ambientes de teste; nunca desabilite validação em produção. Considere certificate pinning para APIs críticas, fixando o certificado esperado na aplicação.
