Falhas do tipo CWE-347

766 resultados

Divulgação de informações

A aplicação expõe dados sensíveis (credenciais, tokens, informações pessoais, detalhes técnicos) a atores não autorizados através de canais inseguros, logs, mensagens de erro ou respostas HTTP. O risco está em que essas informações podem ser capturadas, armazenadas ou usadas para ataques subsequentes.

Exemplo

Uma API retorna stacktrace completo (com caminhos internos e bibliotecas) em resposta de erro; ou um formulário envia senha em texto plano via HTTP; ou logs de produção contêm tokens de autenticação visíveis em backup público no GitHub.

Como mitigar

Sanitize mensagens de erro para o usuário (log completo apenas internamente), use HTTPS/TLS obrigatório para dados sensíveis, implemente rotação de secrets e nunca exponha tokens/senhas em logs, respostas ou comentários de código. Revise regularmente o que é exposto em respostas da aplicação e em pontos de debug.
