Permissões padrão incorretas

Ocorre quando um software cria arquivos, diretórios ou recursos com permissões padrão muito permissivas, expondo dados sensíveis a usuários não autorizados do sistema. O risco é que qualquer outro processo ou usuário consegue ler, modificar ou deletar informações que deveriam ser privadas.

Ejemplo

Um aplicativo cria um arquivo de configuração com senha de banco de dados com permissões 0644 (legível por qualquer usuário), em vez de 0600 (só o dono). Outro usuário no mesmo servidor consegue ler esse arquivo e obtém as credenciais.

Cómo mitigar

Defina permissões explícitas e restritivas no ato da criação (use umask apropriado, chmod, ou APIs de segurança). Sempre revise e documente quais permissões cada recurso deve ter, testando a realidade no sistema de arquivos ou controle de acesso após o deploy.
