Validação inadequada de certificados SSL/TLS

A aplicação não valida corretamente o certificado SSL/TLS do servidor remoto, aceitando certificados inválidos, expirados ou de domínios diferentes. Isso permite ataques man-in-the-middle onde um atacante intercepta a comunicação mesmo com criptografia, comprometendo a confidencialidade e integridade dos dados.

Ejemplo

Uma API cliente ignora erros de validação de certificado (ex: desabilita verificação de hostname ou ignora exceções de certificado inválido) e faz requisições HTTPS para servidores externos. Um atacante na rede intercepta o tráfego, apresenta seu próprio certificado, e consegue ler dados sensíveis como tokens de autenticação ou credenciais.

Cómo mitigar

Sempre validar certificados: verificar hostname, data de validade e cadeia de confiança. Usar bibliotecas padrão do seu runtime (HttpClient do .NET, requests do Python, etc.) com validação ativada por padrão. Nunca desabilitar validação SSL/TLS em produção; se precisar em desenvolvimento, use variáveis de ambiente e revise criticamente o código antes de deploy.
