**Nome do software vulnerável e versões afetadas** Versões do Nautobot anteriores à 1.6.10 Versões do Nautobot anteriores à 2.1.2 **Descrição** O Nautobot é uma fonte de verdade de rede e uma plataforma de automação de rede desenvolvida como um aplicativo web. Devido à sanitização inadequada de entradas, quaisquer campos editáveis pelo usuário que suportem renderização Markdown são potencialmente suscetíveis a ataques de cross-site scripting (XSS) por meio de dados criados de forma maliciosa. Os campos afetados incluem `Circuit.comments`, `Cluster.comments`, `CustomField.description`, `Device.comments`, `DeviceRedundancyGroup.comments`, `DeviceType.comments`, `Job.description`, `JobLogEntry.message`, `Location.comments`, `Note.note`, `PowerFeed.comments`, `Provider. noc contact`, `Provider.admin contact`, `Provider.comments`, `ProviderNetwork.comments`, `Rack.comments`, `Tenant.comments`, `VirtualMachine.comments`, o conteúdo de quaisquer campos personalizados do tipo `markdown`, os atributos `description` da classe de tarefa e a configuração do sistema `SUPPORT MESSAGE`. **Recomendações** Para versões do Nautobot anteriores à 1.6.10, atualize para a versão 1.6.10 ou posterior para resolver o problema. Para versões do Nautobot anteriores à 2.1.2, atualize para a versão 2.1.2 ou posterior para resolver o problema. Como solução alternativa temporária, considere restringir o acesso a campos editáveis pelo usuário que suportem renderização Markdown até que um patch seja aplicado.

**Name of the Vulnerable Software and Affected Versions** Nautobot versions 1.x through 1.6.6 Nautobot versions 2.0.x through 2.0.5 **Description** Nautobot is a Network Source of Truth and Network Automation Platform built as a web application atop the Django Python framework with a PostgreSQL or MySQL database. The URLs "/files/get/?name=..." and "/files/download/?name=..." are used to provide admin access to files that have been uploaded as part of a run request for a Job that has FileVar inputs. Under normal operation, these files are ephemeral and are deleted once the Job in question runs. However, in the default implementation used in Nautobot, as provided by `django-db-file-storage`, these URLs do not by default require any user authentication to access; they should instead be restricted to only users who have permissions to view Nautobot's `FileProxy` model instances. Note that no URL mechanism is provided for listing or traversal of the available file `name` values, so in practice, an unauthenticated user would have to guess names to discover arbitrary files for download, but if a user knows the file name/path value, they can access it without authenticating. **Recommendations** To resolve the issue, update to Nautobot version 1.6.7 or later for the 1.x branch. To resolve the issue, update to Nautobot version 2.0.6 or later for the 2.0.x branch. As a temporary workaround, consider restricting access to the `/files/get/?name=...` and `/files/download/?name=...` API endpoints until a patch is available. Restrict access to the `FileProxy` model instances to minimize the risk of exploitation.
