Permissões padrão incorretas

Ocorre quando um recurso (arquivo, diretório, banco de dados, serviço) é criado com permissões padrão excessivamente permissivas, expondo dados ou funcionalidades a usuários não autorizados. O desenvolvedor ou administrador não restringe explicitamente o acesso, deixando a configuração padrão do sistema, que geralmente é insegura.

Example

Um aplicativo cria arquivos de cache com informações sensíveis (tokens, chaves de API) com permissões 644 (leitura para todos), permitindo que qualquer usuário local da máquina leia esses dados. Ou um bucket S3 é criado com acesso público habilitado por padrão, expondo documentos confidenciais.

How to mitigate

Defina explicitamente permissões restritivas no código (ex: 0600 para arquivos sensíveis, 0700 para diretórios) e revise configurações padrão de infraestrutura antes do deploy. Automatize verificações de permissões em pipelines CI/CD e aplique o princípio do menor privilégio desde a criação dos recursos.
