Permissões padrão incorretas

Ocorre quando um recurso (arquivo, diretório, registro, objeto) é criado com permissões padrão que são muito permissivas, permitindo acesso não autorizado. O código não define explicitamente permissões restritivas, deixando o sistema usar padrões inseguros que muitas vezes permitem leitura ou escrita por usuários não previstos.

Exemplo

Um aplicativo cria um arquivo de configuração com credenciais em /tmp/config.ini sem definir permissões — o sistema deixa o arquivo legível por qualquer usuário local (644), expondo senhas. Ou um diretório de upload recebe 777 como padrão, permitindo que qualquer pessoa execute scripts maliciosos nele.

Como mitigar

Sempre defina permissões explícitas e restritivas no momento da criação (umask 0077 para sensíveis, validar permissões em código). Para arquivos com secrets, use 0600 (apenas proprietário); para diretórios de aplicação, 0755 no máximo. Valide periodicamente permissões em produção e documente o modelo de acesso esperado.
