# Bypass de Filtro de Injeção SQL com Codificação XML
Notas sobre Bypass de Filtro de Injeção SQL com Codificação XML para laboratórios da PortSwigger Web Security Academy, incluindo fluxo de exploração, teste de payloads, validação no Burp Suite e contexto de remediação.
### SQL Injection com Bypass de Filtro via Codificação XML
Este laboratório contém uma vulnerabilidade de SQL injection no recurso de verificação de estoque. Os resultados da requisição são retornados na resposta da aplicação; então podemos usar um `UNION` ataque para recuperar dados de outras tabelas. / O banco de dados contém uma `users` tabela contendo os nomes de usuário e senhas dos usuários cadastrados. Para resolver o laboratório, realize um ataque de SQL injection para recuperar os IDs do usuário administrador e, em seguida, faça login na conta dele.
Exemplos fornecidos:
{% code overflow="wrap" %}
```xml
22 union select 1
```
{% endcode %}
* Extensão Hackvertor — entidades decimais
{% code overflow="wrap" %}
```xml
2<@dec_entities>2 union select 1
<@dec_entities>
2 union select password from users where username='administrator'
```
{% endcode %}

## 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/web/sql-injection/sql-injection-filter-bypass-via-xml-encoding.md?ask=&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.
