Falhas do tipo CWE-294

213 resultados

Exposição de informações sensíveis a atores não autorizados

Fraqueza na qual dados sensíveis (credenciais, chaves, PII, tokens) são acessíveis por usuários ou processos que não deveriam ter acesso. Ocorre por falhas em controle de acesso, armazenamento inadequado ou transmissão desprotegida, permitindo vazamento ou roubo dessas informações.

Exemplo

Uma aplicação grava tokens de autenticação em logs em texto plano acessíveis via endpoint público, ou armazena senhas sem hash em banco de dados com permissões leitura aberta. Um atacante consegue ler essas credenciais e impersonar usuários legítimos.

Como mitigar

Implemente controle de acesso rigoroso baseado em papéis (RBAC/ABAC), criptografe dados sensíveis em repouso e em trânsito (TLS, AES), nunca registre credenciais em logs, e revise regularmente permissões de arquivos e endpoints para garantir que apenas atores autorizados acessem informações críticas.
